| T01 - TURBO CODES: PERFORMANCE ANALYSIS, DESIGN, ITERATIVE DECODING AND APPLICATIONS |
Duration: Full-Day – Sunday 20 June – 8:30 - 17:00
Instructor: Sergio Benedetto, Politecnico di Torino
Abstract:
Turbo-like codes are formed by concatenating two or more simple
constituent convolutional in a parallel or serial fashion through
one or more interleavers. They have astonishing performance close
to the Shannon limits, yet enabling simple decoding algorithms whose
complexity is comparable to that of decoding the constituent codes.
After their invention in 1993, they have been inserted and standardized
in several systems, like W-CDMA, DVB-RCS, CCSDS. Also, numerous
applications of the so-called “turbo principle” applied
to fields like equalization, multiuser detection, carrier synchronization,
and others has been successfully proposed. This tutorial provides
an understanding of the principles governing the codes behavior,
analytical tools to evaluate the maximum likelihood performance,
design rules for both the constituent codes and the interleaver,
explanation of the maximum-a-posteriori algorithms which form the
core of the iterative decoding algorithms, extensive analytical
and simulation results, a comparative analysis of the implementation
complexity, and a number of important applications like third-generation
wireless communications, and deep-space communications. A performance/complexity
comparison on a case study with low-density parity-check codes will
also be described.

Abstract:
Orthogonal frequency division multiplexing (OFDM) has been shown to
be an effective technique to combat multipath fading in wireless communications.
This approach has been chosen as the standards in several outdoor
and indoor high-speed wireless data applications. The capacity of
wireless communication systems can be further improved if the emerging
MIMO techniques are used in OFDM systems. This tutorial presents the
basic principles of OFDM and discusses the problems and some of the
potential solutions to the practical issues in implementing such a
system, including techniques for peak-to-average power ratio reduction,
time and frequency synchronization, channel estimation, adaptive antenna
arrays and transmitter diversity. Then we briefly introduce MIMO techniques
and present the application of these techniques to OFDM wireless communication
systems. We conclude with a discussion of current and proposed systems.

| T04 - WIRELESS MULTIMEDIA COMMUNICATIONS |
Duration: Full-Day – Sunday 20 June – 8:30 - 17:00
Instructor: Lajos Hanzo, University of Southampton
Abstract:
This tutorial is based on the presenter's Wiley/IEEE Press monographs:
Wireless Video Communications (2001), Voice Compression and Communications
(2001) Turbo Coding, Turbo Equalization and Space-Time Coding (2002),
Adaptive Wireless Transceivers (2002), Single- and Multi-Carrier DS-CDMA
(2003), OFDM and MC-CDMA (2003). The overview provides an insight
into the effects of turbo-coded, turbo-equalized and space-time coded
near-instantaneously adaptive TDMA, CDMA and OFDM transceivers on
the achievable speech and video performance of wireless multimedia
systems. These transceivers require near-instantaneously adaptive
speech, audio and video codecs that generate - under transceiver control
- exactly the number of source coded bits that the adaptive transceiver
is capable of delivering at the required integrity, given the instantaneous
channel quality. The design examples used will include sophisticated
next-generation transceivers employing the Advanced Multi-Rate (AMR)
speech codec and the H.263 video codec. The tutorial is concluded
by demonstrating the potential performance gains attained by an integrated
turbo transceiver design, benefiting from iterative joint source decoding,
channel decoding and demodulation.

| T05 - THE TURBO PRINCIPLE IN SPACE-TIME CODING, EQUALIZATION AND CODED MODULATION FOR WIRELESS CHANNELS |
Duration: Half-Day – Sunday 20 June – 8:30 - 12:00
Instructor: Joachim Hagenauer, Munich University of Technology
Abstract:
The turbo principle can be used in a more general way than just for
the decoding of parallel concatenated codes as originally designed.
It will be shown in this tutorial that the turbo principle is a general
concept in communications that is applicable to a variety of problems,
e.g., to parallel and serial decoding, space-time coding for MIMO
channels, equalization and coded modulation. Using log-likelihood
algebra for binary codes, simple examples will be given to show the
essentials of the turbo iteration. Several standard algorithms for
soft-in/soft-out decoding/detection like the basic symbol-by-symbol
MAP (APP) algorithm and its derivates (Log-max MAP, SOVA) as well
new algorithms like the list sequential decoder (LISS) will be discussed.
The performance of the iterative process will be investigated with
the extrinsic (EXIT) chart. Special emphasis will be given to the
application of the turbo principle in wireless communications and
for Space Time decoding (STC) in the multiple-input/multiple output
(MIMO) channel. Equalizers and MIMO detectors will be described which
can handle high-complexity systems with QAM signal constellations,
multiple antennas and extensive multipath.

| T06 - SURVIVABLE OPTICAL NETWORKS |
Duration: Half-Day – Sunday 20 June – 8:30 - 12:00
Instructor: Hussein T. Mouftah, University of Ottawa
Abstract:
The emergence of Wavelength Division Multiplexing (WDM) technology
has provided a new dimension in exploiting the huge capacity of optical
fibers. WDM allows multiple optical signals to be transmitted simultaneously
and independently in different optical channels over a single optical
fiber and thus provides enormous bandwidth at the optical layer to
different higher network layers. In view of this fact, wavelength-routed
WDM networks have been widely considered to be the potential network
architecture for future wide area networks. Due to the huge transmission
capacity, however, a single failure in a wavelength-routed WDM network
may cause a large amount of data loss, which would greatly degrade
the quality of service (QoS), and even disrupt the services being
offered to the customers. For this reason, network survivability has
been a crucial concern in wavelength-routed WDM networks. A network
must support various protection and restoration capabilities in order
to provide guaranteed services to their customers. While survivability
capabilities are now available at different higher layers (e.g. IP,
ATM, SONET, etc.), to provide survivability at the optical layer is
still attractive because of its fast recovery mechanisms, efficient
resource utilization, and some other reasons.
Optical layer protection and restoration has been extensively studied
for wavelength-routed WDM networks. To survive different types of
network failures (e.g. a fiber cut or a node fault), a variety of
optical layer protection and restoration schemes have been proposed
with the objectives to provision backup paths rapidly and utilize
network resources efficiently. In this tutorial, we will address faults
in optical networks and in particular wavelength division multiplexing
(WDM) networks and optical network control architectures. We will
cover dedicated and shared protection schemes including path and link
shared protection, short leap shared protection and channel protection.
We will address the Routing and Wavelength Assignment (RWA) problem
within survivable wavelength-routed WDM networks and in particular
the survivable routing and spare capacity allocation problem. Finally,
we will provide a brief coverage on tools for the design and performance
evaluation of survivable optical networks.

| T08 - WIRELESS AD-HOC NETWORKS |
Duration: Half-Day – Sunday 20 June – 8:30 - 12:00
Instructor: Carla-Fabiana Chiasserini, Politecnico di Torino
Abstract:
An ad-hoc network is composed of a set of wireless nodes that can
spontaneously form a network without the need for a fixed infrastructure
or a centralized controller. Various ad-hoc network solutions have
been devised, from local area networks (WLANs), to personal area networks
(WPANs). Common features to all ad-hoc systems are the use of a shared
medium for data transfer and of multi-hop communications to reach
a distant destination. These characteristics pose challenging issues,
especially related to traffic routing and access control.
The tutorial will present some of the emerging ad-hoc networking technologies.
In WLANs, some of the major issues in medium access control and its
interaction with higher layers will be described in the context of
the IEEE 802.11 technology. Bluetooth systems will be presented as
an example of WPAN technology and the problem of forming an efficient
network topology will be discussed. In the context of mobile ad-hoc
networks, particular attention will be given to traffic routing and
the most relevant solutions will be outlined. Then, some theoretical
results in ad-hoc networks will be presented, concerning nodes cooperation
schemes and network capacity.

| T09 - QoS IN MULTIMEDIA NETWORKS |
Duration: Half-Day – Sunday 20 June – 13:30 - 17:00
Instructor: Nirwan Ansari, New Jersey Institute of Technology
Abstract:
Multimedia consists of voice, video, and data in the same application.
Sample multimedia applications include videoconferencing, video on
demand, distant learning, distributed games, and movies on demand.
Providing Quality of Service (QoS) for multimedia streaming has been
a difficult and challenging problem. This tutorial provides an overview
of the potential approaches to address this challenge. Video fundamentals
are first introduced. We then present QoS evaluation/ performance
metrics from the network, multimedia quality, and user perception
perspectives. The rest of the tutorial covers the possible solutions
to QoS provisioning for multimedia streaming, including the network
support, the multimedia encoding support, the application level QoS
support, and the service provider support. For the network support,
we introduce different technologies for different types of networks
such as ATM and IP networks. Several promising service models recently
proposed by IETF (Internet Engineering Task Force) for supporting
multimedia traffic over IP will be discussed. For the multimedia encoding
support, we will review several encoding techniques such as layer
encoding, temporal scalable encoding, and spatial scalable encoding
that can be employed to facilitate QoS support for transmission over
different network characteristics. For the application level support,
congestion control and error control methods are reviewed to provide
application level QoS support. For the service provider support, we
investigate how proxy caching can be used to minimize bandwidth requirement
and improve multimedia quality.

| T10 - WIRELESS SENSOR NETWORKS |
Duration: Half-Day – Sunday 20 June – 13:30 - 17:00
Instructor: Erdal Cayirci, Istanbul Technical University
Abstract:
Advances in digital electronics, embedded systems and wireless communications
lead the way to a new class of ad-hoc networks, namely wireless sensor
networks (WSNs). WSNs have a wide range of potential applications,
including security and surveillance, control, actuation and maintenance
of complex systems, and fine-grain monitoring of indoor and outdoor
environments. They differ from conventional network systems in many
aspects. WSNs usually involve a large number of spatially distributed,
energy-constrained, self-configuring and self-aware nodes. Furthermore,
they tend to be autonomous and require a high degree of cooperation
and adaptation to perform the desired coordinated tasks and networking
functionalities. As such, they bring about new challenges and design
considerations, which go much beyond conventional networks. These
design considerations, which are the reasons to develop new schemes
and technologies rather than using available, will be explained in
this tutorial, where we also present a survey of protocols and algorithms
proposed thus far for sensor networks. Our aim is to provide a better
understanding of the current research issues in this field. Our tutorial
is organized as follows: After introduction, we present potential
sensor network applications. Then, we discuss the factors that influence
the sensor network design, and provide a detailed investigation of
current proposals in this area. In conclusion, we identify the open
research issues in sensor networks and summarize some current research
projects.

| T11 - AN IN-DEPTH INTRODUCTION TO IP MULTICAST |
-CANCELLED-
Duration: Half-Day – Sunday 20 June – 13:30 - 17:00
Instructor: Christian Jacquenet, France Telecom
Abstract:
The Internet is becoming a privileged support for a wide range of
IP service offerings, ranging from accessing the web to value-added
services, such as IP videoconferencing. The subsequent growth of the
IP traffic is also related to the development of bandwidth-consuming
applications, and some of them should benefit from the receiver-initiated
IP multicast transmission scheme for the purpose of reducing the resource
consumption, e.g. within the context of the deployment of services
like live broadcasting or Web TV broadcast. The IP multicast transmission
scheme relies upon the deployment and the maintenance of distribution
trees that convey the traffic towards the receivers who have subscribed
to a given service. Multicast distribution trees are built by means
of the activation of multicast routing protocols, which rely upon
the information carried by unicast routing protocols for the identification
of the best routes that lead to the multicast sources.
In this tutorial, we describe the basic protocol components of IP
multicast: from the subscription procedure based upon the use of the
Internet Group Management Protocol (IGMP), to the dynamic establishment
and maintenance of multicast distribution trees, by means of the Protocol
Independent Multicast routing protocol (PIM), which has become the
de facto standard for IP multicast routing. We also discuss
both the Any Source Multicast (ASM) and the Source Specific Multicast
(SSM) service models, and how such services can be deployed in a multi-service
Internet environment, based upon the intra-domain/inter-domain taxonomy.

| T12 - INTERNET TRAFFIC MONITORING AND ANALYSIS: METHODS AND APPLICATIONS |
Duration: Half-Day – Sunday 20 June – 13:30 - 17:00
Instructor: J. Won-Ki Hong, POSTECH
Abstract:
Today, multi-gigabit networks are becoming common in Internet service
providers (ISP) and enterprise networks. The bandwidth of ISP's backbone
networks is evolving from OC-48 (2.5Gbps) to OC-192 (10Gbps) to support
rapidly increasing Internet traffic. Also, enterprise networks are
evolving from 100-Mbps or 1-Gbps to multi-gigabit networks. Further,
the types of traffic on these networks are changing from simple text
and image based traffic to more sophisticated and higher volume traffic
(such as streaming rich media, voice and peer-to-peer). Monitoring
and analyzing such high-speed, high-volume and complex network traffic
is needed, but it lies beyond the boundaries of most traditional monitoring
systems. Various application areas are requiring information generated
from such traffic monitoring and analysis. For example, such information
can be used for usage-based billing, denial-of-service (DOS) attack
analysis, user network usage analysis, network capacity planning,
customer relationship management, and so on. Many of these applications
are critical to the business, operations and management of ISPs and
enterprises.
This tutorial will present the techniques involved in capturing and
examining packets, generating and storing flows, and analyzing them
for various purposes and applications. Algorithms for analyzing Internet
application traffic such as multimedia streaming, multimedia conferencing,
game and peer-to-peer will be presented. Also, algorithms and methods
for detecting network security attacks such as DoS/DDoS attacks and
Internet worm virus attacks will be presented. Monitoring and analysis
tools such Cisco NetFlow, cflowd, FlowScan, argus, and NG-Mon are
examined. Real-world application areas of such monitoring and analysis
tools will also be explored.

| T13 - INTERNET PROTOCOL V6 |
Duration: Full-Day – Thursday 24 June – 8:30 - 17:00
Instructor: Laurent Toutain, ENST Bretagne
Abstract:
The success of the first version of the IP protocol (IPv4) led to
an exhaustion of the addressing space. The standardization of the
new protocol, known as IPv6, started in 1992. After more than 10 years
of effort, the standardization of IPv6 is almost over. The new protocol
stack is included in most of the operating systems and routers. The
new version of the protocol retains the features that made IPv4 successful.
In addition a better engineering ensures the evolution of the protocol.
Nevertheless, the introduction of IPv6 in the network is a great challenge
since a vast majority of equipments, applications and protocols need
to be modified and must continue to interoperate.
This tutorial explains the benefits and the drawbacks of the IPv6
protocol. It includes the features covered by current standards and
drafts and the subjects that remain as research topics. A survey of
different IETF working groups and other organizations working on IPv6
will be given. A comprehensive description of the IPv6 and associate
protocols will be given, highlighting the differences and similarities
with IPv4. The presentation will also cover the addressing rules,
the process to request prefixes and the evolution of the DNS to handle
those addresses. We will also present auto-configuration, which is
one of the new attractive features of IPv6. The large size of addresses
drastically reduces the risk of address collisions between hosts on
the same link. The tutorial will also present the problems related
to security and limitation of this model that cannot be compared to
a real plug-and-play mechanism. We will cover recent extensions that
allow the provider to configure CPE. A large part of the tutorial
will be dedicated to transition mechanisms from IPv4 to IPv6 at different
levels. The use and the performance of different tools like tunnels
or the use of 6PE with MPLS will be discussed. Strategies and problems
to introduce IPv6 in site will be explained with the description of
protocols and mechanisms that can be used either to get the connectivity
(6to4, Teredo, ISATAP) or to allow applications to communicate between
the two versions of the protocol (dual stack, DSTM, SOCK, &).
We will describe some network architectures like 3GPP, where IPv6
is mandatory. The tutorial will end with some programming aspects
concerning IPv6 and with the links to other protocols developed by
the IETF, like SCTP.

| T14 - DYNAMIC SPECTRUM MANAGEMENT FOR DSL |
Duration: Half-Day – Thursday 24 June – 8:30 - 12:00
Instructor: John M. Cioffi, Stanford University
Abstract:
Dynamic Spectrum Management (DSM) enables DSL to 100 Mbps symmetric
speeds to customers, which represents a significant increase of existing
DSL capabilities. There are two major steps in DSM: The first of those
is the use of measured line parameters to control adaptively and politely
the spectral behavior of increasing numbers of DSL lines in a shared
cable or binder. The second is the use of coordinated DSLAMs to eliminate
all or most crosstalk between lines. These steps can be taken efficiently
in DSL deployments without regulatory intervention and with decreasing
service, equipment and component cost per subscriber. The tutorial
overviews these steps and illustrates some basic architectures.

| T16 - ULTRA WIDEBAND RADIO |
Duration: Half-Day – Thursday 24 June – 8:30 - 12:00
Instructors:
Andreas F. Molisch, Mitsubishi/Lund University
Moe Z. Win, Massachusetts Institute of Technology
Abstract:
Ultra-wide bandwidth (UWB) transmission systems have gained recent
interest in the scientific, commercial and military sectors. Wide
bandwidth provides fine delay resolution, making UWB a viable candidate
for communications in dense multipath environments, such as short-range
or indoor wireless communications. By virtue of their robustness against
fading and superior obstacle penetration, UWB systems allow reliable
communication in extremely challenging environments where there are
many obstacles producing dense multipath. Therefore, they are currently
under consideration for high data rate communications and sensor networks,
because they allow low-cost production and reuse of (already occupied)
spectrum. UWB is also highly interesting for military application
because it provides low probability of detection as well as anti-jam
capabilities. Interest in UWB systems has intensified recently due
to the ruling by the US Federal Communications Commission (FCC) concerning
UWB emission masks. This ruling opens the way for coexistence with
traditional and protected radio services and allows the potential
use of UWB transmission without allocated spectrum. Standardization
bodies (like IEEE 802.15) have started to develop standards for UWB
systems and companies are announcing products. In this tutorial, we
will give a technical overview that will allow the attendants to distinguish
between commercial hype and the true technical possibilities.

| T20 - CO-EXISTENCE IN THE 2.4 GHZ BAND: CHALLENGES AND SOLUTIONS |
Duration: Half-Day – Thursday 24 June – 8:30 - 12:00
Instructor: Nada Golmie, National Institute of Standards
and Technology
Abstract:
Due to its almost global availability, the 2.4 GHz Industry, Scientific
and Medical (ISM) unlicensed frequency band has become popular for
low cost radio solutions including Bluetooth, wireless local area
networks (WLANs) based on the IEEE 802.11 standard, wireless personal
area networks (WPANs) and others. No license is required to use this
band, but systems must follow rules defined in the Federal Communications
Commission Title 47 of the Code for Federal Regulations Part 15 relating
to total radiated power and the use of spread spectrum and frequency
hopping. The major downside of using the ISM band is the interference
caused by other users. While the spread spectrum and power rules are
fairly effective in dealing with interference when the radios are
physically separated, the same is not true for close proximity radios
on the same laptop or desktop. Now that WPAN and WLAN technologies
are developing fast and will soon be crowding the ISM band, there
is a growing interest in studying the coexistence issues.
Using two representative technologies, namely Bluetooth (IEEE 802.15.1)
and IEEE 802.11b, this tutorial explores the effects of mutual interference
of WPAN and WLAN devices and investigates solutions to mitigate it.
The presentation is divided into two parts. In the first part, we
outline a methodology for quantifying the impact of interference using
analysis, experimentation, and simulation. While analytical models
can give a first-order approximation to the impact of interference,
they often make assumptions concerning the traffic distributions and
the operation of the medium access control (MAC) protocol, which limits
their validity. On the other hand, experimental and simulation results
can be considered more accurate at the cost of being too specific
to the implementation tested. Results using each of these techniques
will be discussed and compared. The second half of the tutorial describes
solutions to the coexistence problem, based on the work of the IEEE
802.15.2 Task Group and the Bluetooth Special Interest Group (SIG).
The focus is on MAC solutions that can augment or enhance traditional
filtering, anti-jamming, and physical layer techniques. The solutions
considered by these groups range from collaborative schemes to be
implemented in the same device to fully independent solutions that
rely on interference detection and estimation. We will present some
of the most promising techniques including power control, adaptive
frequency hopping and scheduling for Bluetooth, rate scaling for WLAN,
and time sharing between Bluetooth and 802.11 signals using TDMA.
Realistic scenarios will be considered for each scheme and performance
trends and trade-offs will be discussed.

Instructor: Erik B. Dahlman, Ericsson Research
Abstract:
Commercial deployment of third generation (3G) wireless systems is
now well underway in many regions of the world. This tutorial aims
at providing a detailed overview of the main 3G radio-access technologies
(WCDMA, cdma2000/1x, and TDD) as well as some insight into key challenges
related to the efficient deployment of 3G wireless systems. The first
part of the tutorial provides a short history of 3G technology, including
the early days of research and standardization. The second part of
the tutorial gives an overview of the 3G radio-access standards as
developed by the 3GPP and 3GPP2 standard-development organizations.
It also covers recent extensions to the 3G standards, such as High
Speed Downlink Packet Access (HSDPA) for WCDMA (3GPP) and 1x/EV-DV
(3GPP2). We begin with a description of the radio-access network architecture
of the different 3G standards, followed by a description of the radio-access
protocol stacks, including physical layer and layer 2 (MAC and link
control) and radio-resource management/control. As part of this, the
key differences between the different 3G standards are highlighted.
Finally, possible future enhancements and evolution steps of the 3G
technologies are presented. The final part of the tutorial discusses
some of the key technical challenges associated with the commercial
deployment of 3G wireless systems. This includes different deployment
strategies as well as dimensioning rules and necessary trade-offs
in terms of network capacity, coverage, and quality-of-service.

Abstract:
It is expected that there will be a strong market for a rich variety
of wireless internet-based multimedia devices in a not-too-distant
future. It is quite difficult to predict the nature of these devices
as well as the corresponding applications from today; but, it is certain
that those devices and applications will have very different QoS,
rate, delay, and power constraints. Arguably, effective RRM is not
only essential in such future networks, but it is the key element
in feasible and affordable deployment and operation of these networks.
This tutorial will discuss the fundamental dynamics of RRM along with
the current advances in the field; many implementation issues will
be addressed as well. The topics covered will include the followings:
call admission control, QoS provisioning, service prioritization,
scheduling, fairness, hybrid ARQ techniques, user multiplexing, power
control and allocation, adaptive modulation and error control coding,
RRM in multicode and multiple-chip-rate W-CDMA systems, and RRM in
macrodiversity systems.

| T23 - ARCHITECTURE AND REQUIREMENTS OF NEXT-GENERATION WIRELESS NETWORKS |
Duration: Half-Day – Thursday 24 June – 13:30 - 17:00
Instructor: Abbas Jamalipour, University of Sydney
Abstract:
Next generation wireless networks will be accomplished through integration
of advanced networks including the second- and third-generation wireless
cellular systems, broadband satellite systems, wireless local area
networks, short-range connectivity networks, as well as other wire-line-oriented
broadband technologies. The next generation networks will therefore
realize the true idea of heterogeneous networks. The wireless LAN
based on IEEE 802.11 standards and the HiperLAN have already started
their inclusion within the 2.5G/3G cellular systems in order to complement
their relatively low speed and cost effective services with much higher
data rates and much lower cost. Many hot spots around the world are
now covered by wireless LAN and this trend is going to be continued
at an exponential rate. The main standardization bodies for 3G, the
3GPP and 3GPP2, have already started their study on 3G/WLAN internetworking
and a few architectures have already been proposed. Ultimately the
two networks will work in a seamless form and gradually other systems
will join the list to complete the heterogeneous network architecture.
In this tutorial, the main technologies toward the implementation
of next generation networks and their corresponding requirements will
be explained. As the major issues toward the seamless internetworking
among those networks, we will discuss the mobility management and
quality of service establishment in heterogeneous networks, as well
as security techniques to be developed and maintained within the multi-operator
network configuration. Access to subscribers’ database would
become a major issue among all network operators involved in such
heterogeneous network and also handling of security will require more
advanced architectures; all those issues to be discussed in this tutorial.
State-of-the art standardization activities including 3GPP, 3GPP2,
ETSI, IETF, and MWIF toward true internetworking of wired and wireless
networks through a structured and layered architecture will be also
included in the tutorial.

| T24 - DIGITAL RIGHTS MANAGEMENT |
Duration: Half-Day – Thursday 24 June – 13:30 - 17:00
Instructor: Tomas Sander, Hewlett-Packard Laboratories
Abstract:
This tutorial will explore technical aspects of the design of DRM
systems, mixing two points of view. First, viewing the task top-down,
we will consider the overall architecture of a DRM system, emphasizing
clear statements of the aims of the particular system. We will particularly
pay attention to the security aspects of DRM systems. Second, bottom-up,
we will consider many of the technical tools that can be used in building
a DRM system, including key management, authentication, broadcast
encryption, traitor-tracing, auditing measures, payment mechanisms,
watermarking, and tamper resistance. We will also discuss the relationship
to Trusted Computing concepts and DRM. Although the tutorial is mainly
technical in nature we will point to some of the controversial policy
issues raised by DRM technology.

| T25 - VIRTUAL PRIVATE NETWORKS: OVERVIEW OF TECHNICAL APPROACHES FOR SERVICE PROVIDERS AND PROGRESS IN STANDARDIZATION |
-CANCELLED-
Duration: Half-Day – Thursday 24 June – 13:30 - 17:00
Instructor: Marco Carugi, Nortel Networks
Abstract:
The introduction of this tutorial will position the context of virtual
private networks, covering definitions, scenarios and requirements,
providing a classification of technical approaches, as well as a description
of the basic functional building blocks. The second section will cover
the Layer 3 solution space, presenting key elements of CE-based and
network-based approaches, including IPSec, RFC2547 and Virtual Router
based VPNs, and positioning their applicability. The role played by
the MPLS technology will be highlighted (scalability, traffic engineering,
etc.).
The third section will introduce the emerging layer 2 VPN services,
highlighting the shift from legacy Virtual Circuit based solutions
to IP/MPLS based ones and the increased interest in their Metropolitan
network application. Technical approaches, including Virtual Private
Wire services (VPWS), Virtual Private LAN Services (VPLS) and IP over
LAN Services (IPLS), will be presented, as well as positioning against
layer 3 services. Role and recent evolutions of Ethernet technology
influencing future service capabilities (Provider Bridging, QoS, OAM)
will be mentioned. Attractive business scenarios make the very new
area of Layer 1/Optical VPN services an interesting opportunity for
providers' future deployments: application scenarios, network and
service architectures, implementation examples with protocols and
functional constructs specified in various bodies (OIF UNI, IETF GMPLS,
ITU-T ASON) will be presented. Finally, a summary of current standardization
activity will indicate progress achieved inside IETF (L3 and L2 Working
Groups), inside IEEE and MEF (Ethernet based solutions), inside ITU-T
(L1 and Generic VPN architectures). Also, some key work items in standardization
over next period will be provided.

Duration: Half-Day – Thursday 24 June – 13:30 - 17:00
Instructor: Michel Riguidel, ENST
Abstract:
The tutorial provides a global overview of modern security issues
in the future communication networks. It presents a prospective viewpoint
of Internet and mobile wireless security, and gives many starting
points to research on. The author describes the limitations of current
communication security in the rising multimedia communication age,
the need for more complex/subtle security mechanisms and policies.
The tutorial provides a short description of new security paradigms
with the emergence of the ambient intelligence concept and new architectures
(P2P, Grids, Virtual entities …). The new environment (“always
connected”, nomadic users, mobile infrastructures, heterogeneity
…) and the pregnant morphology of information systems require
a drastic change of our static vision of legislations and rules for
security policies to be enforced, implemented and verified. The tutorial
will address new aspects of protection and security functions required
for users, in a private infosphere (virtual identity, authentication
with time and space, anonymity, non-observability, digital rights
management, biometry), in a networked infosphere (virtual private
networks, new firewalls, inter-network security), and in an open public
infosphere.
The tutorial will discuss emerging vulnerabilities and outlines a
systemic approach to security aimed at protecting critical infrastructures
and attenuating the risk of inter-infrastructure cascade effects in
the event of serious accident or cyber-attack. Finally, the speaker
gives an overview of possible future developments and research areas
that need to be explored to provide security in the future communication
networks: V2V (Virtual to Virtual) architectures.

| T27 - USING WEB SERVICES FOR VALUE ADDED SERVICES ENGINEERING IN NEXT GENERATION NETWORKS: STATE OF THE ART AND CASE STUDIES |
-CANCELLED-
Duration: Half-Day – Thursday 24 June – 13:30 - 17:00
Instructor: Roch H. Glitho, Ericsson and Concordia University
Abstract:
Web services are emerging as the standard paradigm for application-to-application
interaction. From end-users’ perspective, value added services,
or more simply services, can be defined as anything that goes beyond
two-party voice call. Several approaches (e.g. Parlay/OSA, SIP servlet)
have been proposed in the past for engineering them in next generation
networks. Web services are now emerging as a viable alternative and
standardization has started in forums such as the Open Mobile Alliance
(OMA). Using Web services for engineering value added services in
next generation networks raises many issues: Level of abstraction
for accessing network functionality; environment for developing and
running value added services in a secured, controlled and accountable
manner; performance. This tutorial presents the state-of-the-art and
illustrates it by concrete case studies. We start by giving background
information on next generation networks, Web services and service
engineering in the pre-Web services era. After that we identify the
main issues raised by the use of Web services in next generation networks.
We then review the state-of-the-art as per the emerging Parlay-X,
Parlay Web services, ECMA, and OMA specifications. We end by case
studies that cover the definition of Web services for accessing call
control and presence functionality; the implementation of these Web
services; the engineering of concrete value added services using them;
and the inherent performance issues.
About the instructor:
Roch H. Glitho received a Ph.D. in tele-informatics (Royal Institute
of Technology, Stockholm, Sweden) and an M.Sc. degrees in business
