Tutorial I-A: Transporting Real-Time Multimedia Over Broadband Wireless Networks

Time: 9:30-1:00pm

Tutorial Description: Recent developments in wireless packet networks (3G and beyond) indicate a clear trend towards offering services that support the delivery of real-time multimedia (i.e., voice and video) along with traditional data traffic. Such services must be capable of providing quality of service (QoS) guarantees for voice and video packets while at the same make efficient use of the scarce bandwidth resource. In this tutorial, we provide a comprehensive and in-depth survey of available mechanisms for supporting the real-time delivery of multimedia over wireless networks. This tutorial will also cover the following issues in this area:

§ Nature of the channel fading process,

§ Characteristics of multimedia sources

§ Types of source coding that are used or expected to be used for the delivery of multimedia over wireless (including, MPEG-4),

§ Support provided by the receiver in the form of error concealment and buffering

§ Open research issues

Who should attend: Developers of wireless multimedia applications, wireless engineers and network planners, researchers.

Tutorial Description: This tutorial provides a practical understanding of virtual private networks (VPNs) and a foundation for evaluating them from the perspectives of business benefits as well as technical requirements. Examples provide an insightful view of the advantages of this technology and the pitfalls to avoid in choosing or designing a VPN. The tutorial also emphasizes the technical aspects related to the planning, implementation, operation and administration of VPNs. The tutorial is aimed at network engineers, software designers and administrators involved in the planning, implementation and administration of VPNs. It is also aimed at executives, managers, sale representatives, and upper-level technicians who want to familiarize with VPNs and the technologies that make them.

§ Basics: Defining the VPN and how to use it

§ Internet versus other VPNs (ATM, frame relay)

§ Security: Encryption (secret/public key); user authentication, authorization and key management (certificate authorities)

§ Tunneling: PPTP, L2F, L2TP, IPSec, Application-level VPN protocols

§ MPLS VPNs for QoS support

§ Software versus hardware solutions

§ VPN Planning

§ Administration and Service Level Agreements

Who should attend: Network engineers, network operators and planners, researchers.

Dr. Boutaba is the recipient of the Premier's Research Excellence Award.

Tutorial Description: This tutorial will introduce the various video compression techniques and the techniques that can be used to stream multimedia over various types of data networks.

§ Multimedia Basics: Basic compression technologies, Multimedia formats for audio such as PCM & MPEG and for video (such as H.261, H.263, MPEG-1, MPEG-2, MPEG-4

§ Multimedia Streaming: Live video streaming, Video conferencing over ISDN, and Video streaming over the Internet

§ Congestion management and Video adaptation

§ Application Example: Vic and Vat

§ Stored video streaming: Content distribution networks, Real networks RealVideo

§ Scalability issues for video distribution

§ Adaptability issues for video distribution

§ Multimedia futures: Dealing with the wireless scenario, small devices and security issues

§ The future of video streaming

Who should attend: Multimedia application developers, traffic engineers, researchers.

Speaker Bio: Dr. Wu-chi Feng received his Ph.D degree from the University of Michigan in 1996. His research interests include multimedia systems, wireless network support for multimedia, and middleware services. He is currently an Associate Professor at the Oregon Graduate Institute in Portland, Oregon. He was awarded an NSF CAREER award for his research in video streaming protocols and video-on-demand systems.

Tutorial Description: This tutorial will focus on network services provisioning and configuration in a service provider's layer 3 IP data core and layer 2 TDM/DWDM based transport network. We focus on layer 2 and layer 3 network services, which need to be provisioned before provisioning higher layer services on the network such as various multi-media. We consider IP QoS and MPLS TE (traffic engineering) enabled IP core. Service provisioning in a multi-domain, multi-technology, multi-vendor, multi-layer network is a challenging task. This tutorial will cover the following issues:

§ Integrated MPLS TE and QoS provisioning.

§ Integrated layer 2 and layer 3 provisioning.

§ Offline planning result of which may be used for optimized provisioning throughout the network.

§ Traffic planning methods for computing traffic history based paths, IP QoS paths based on service QoS requirements, and service level or traffic conditioning agreements), protected or backup paths for primary paths, QoS constrained backup paths.

§ Integrating data and transport network into all IP network using Optical UNI (O-UNI)

§ GMPLS based unified control plane (UCP).

§ Detail examples of selected network elements, architectures, and OSS systems will be provided.

Who should attend: Network engineers, network operators and planners, researchers.
