Level: Introductory

This tutorial is an introduction to current IP multicast practice, with an emphasis on inter-domain routing (especially inter-Autonomous System peerings.) The session will cover the M-BGP, MSDP, PIM Sparse Mode, and IGMP protocols, and how these protocols interoperate to provide scalable IP multicast service. Both the Any Source Multicast (ASM) and Source Specific Multicast (SSM) multicast service models will be discussed.

About the Presenter
Bill Nickless works for the Mathematics and Computer Science Division of Argonne National Laboratory. He has been working for the past 1.5 years with the Access Grid project, which fundamentally depends on IP multicast service for success. During that time he has helped bring up multicast service at sites ranging from National Laboratories to Native American Tribal Colleges. He is also active in the IETF MSDP and MBONED working groups, and is the author of an Internet Draft covering the topics presented in this tutorial.
