ULg AIM Internet Next Generation : IPv6 and RSVP
April 16, 1997 - Liège
Prof. Jean-Yves Le Boudec

* Introduction

The Internet is now coming to a turn, which will change its nature and impact the whole computer and telecommunication industry. Scalability and adequate support for person to person audio and video services are about to be provided by two new protocols: IPv6 and RSVP. What are those protocols ? What can they promise ? What are their limitations ? The emphasis of the course is on an in-depth understanding of the main ideas behind those two new protocols that will let you to understand the future of networking.

* Table of Contents

A. IPv6: The new Internet Protocol

  1. Motivation

  2. IPv6 Addresses
    • Adress formats, provider based addresses, local addresses
    • Anycast, Unicast and Multicast addresses

  3. Plug and Play
    • Stateless configuration
    • Link local address
    • Solicited node multicast address
    • Stateful configuration
    • Router discovery

  4. IPv6 Basics
    • IPv6 datagram format
    • Flow label
    • Packet forwarding
    • Host sending tables
    • Address Resolution
    • Neighbour Reachability

  5. Other Features
    • Source routing
    • Fragmentation, Path MTU
    • Security and mobility features

  6. Transition
    • IPv4 and IPv6 interworking
    • Isolated IPv6 hosts
    • Dual stack host sending method
    • Automatic tunnels
    • Configured tunnels

B. RSVP: The Resource Reservation Protocol

  1. Integrated Services in the Internet
    • IntServ building blocks
    • Types of Service
    • T-SPEC
    • Main RSVP features

  2. Basic Example
    • Simple point to point scenario
    • Slack Term
    • Path and Resv messages
    • R-SPEC, AdSpec
    • Reservation Setup flows

  3. More Definitions and Examples
    • Path and reservation messages on a multicast tree

  4. Reservation Styles
    • Fixed filter, shared explicit and wildcard filter
    • Reservation merging

  5. Other Protocol Aspects
    • Previous hop registration
    • Tunnelling
    • Link Failure and recovery
    • Soft states
    • Confirmation and Error
    • Killer reservations

  6. Implementation Aspects
    • Router and Host aspects

  7. Perspective
    • RSVP, ST-.II and ATM

C. Conclusion

    The next generation Internet and ATM

Jean-Yves Le Boudec is full professor at EPFL, Lausanne, Switzerland, where he heads the Laboratoire de Réseaux de Communication (LRC). Previously, he worked for Bell-Northern Research, Ottawa, Canada, and at the IBM Zurich Research Laboratory. In the latter position, he was manager of the Customer Premises Network department, where he led the development of control software for an ATM control point product. He was also instrumental in launching LAN Emulation over ATM, through the RACE project "Business CPN" and the ATM Forum. His research currently bears on methods for the native use of ATM in a TCP/IP environment (Arequipa), on many-to-many multicast (ATM Forum) and on the provision of RSVP controlled load services.
