Tutorial T1 8:30AM - 12:00PM

Home Networking, the Next Frontier

Peter Ford, Microsoft

The Internet is becoming a pervasive infrastructure for education, business and government. For most residences, the Internet appears as a single node terminated by a personal computer. As the cost of networking hardware and software continues to decline it opens new opportunities for extending the Internet into homes using low cost LAN technologies and TCP/IP. In this tutorial we will survey the different media being considered for home networking, and the software architectures needed to make networking in the Home possible. We will also survey emerging network technologies as they apply to home networking such as Service Location and IP telephony as well as industry initiatives such as the PC industry's Universal Plug and Play (UPnP) and JINI. The challenges and opportunities of Home Networking is the next frontier of the Internet.

Required Background:
Basic networking concepts such as familiarity with the
Internet Protocol Suite, Appletalk or IPX

Speaker Biography:
Peter S. Ford is a networking architect in Microsoft's Windows Operating Systems Division and has led the program management team in IPSEC, QoS, and TCP/IP for Windows 2000. Prior to joining Microsoft he worked at internetMCI and the Los Alamos National Laboratory. Mr. Ford worked at the National Science Foundation on the program to transition the NSFNET to ISPs and is often blamed for the creation of NAPs.

Tutorial T2 8:30AM - 12:00PM

Differentiated Services, A Framework for Internet-friendly QoS

Kathleen Nichols, Cisco Systems

This tutorial will cover what differentiated services is, background on how the differentiated services approach evolved, current results on use of differentiated services, and the current status in the IETF.

Required Background:
Basic understanding of TCP/IP protocols.

Biography:
Kathleen Nichols is co-chair of the IETF Differentiated Services Working Group, a co-author of RFC 2474 which defines the proposed standard, and a co-author of a number of other differentiated services Internet-Drafts and pending RFCs. She works at Cisco Systems where she is manager of QoS Architectures.

Tutorial T3 1:30PM - 5:00PM

Voice Over IP, Call Control and Signaling

Lyndon Ong, Bay Architecture Laboratory, Nortel Networks

This tutorial provides a basic understanding of the emerging signaling protocols for voice over IP and how they will support unified networking for carrier and enterprise services. The tutorial covers:

Overview of VoIP elements
gateways and voice encoding alternatives
voice transport over IP
signaling and the interworking of packet and circuit networks
Call control protocols for VoIP
the Megaco device control model
Megaco protocol characteristics
peer-to-peer signaling methods - H.323 and SIP
Signaling transport issues
Signaling reliability over IP
Signaling Gateways
Interworking of PSTN signaling networks and IP

Required Background:
Basic understanding of TCP/IP protocols.

Biography:
Lyndon Ong is a Senior Architect in the Bay Architecture Laboratory, responsible for architecture and design of signaling protocols for Nortel Networks' Enterprise Solutions organization. He also consults with Nortel's Carrier Packet Solutions organization in the area of SS7-Internet interworking. Prior to joining Bay Networks, Dr. Ong was a Senior Staff Engineer at Bellcore, where he led the development and specification of SS7 signaling protocols and was active in national and international standards bodies addressing SS7 signaling and ATM network standards.

Tutorial T4 1:30PM - 5:00PM

High Performance Switches and Routers: Theory and Practice

Nick McKeown, Stanford University

In this tutorial, we will study how high performance, multigigabit and terabit switches and routers are architected. The tutorial will cover both theoretical and practical aspects.

Although different in their detailed operation, all high performance packet-switches share three common features:
(1) "Where" (Routing/Classification/Lookup) --- When a new packet arrives the packet switch must decide where the packet is going next, and hence through which port(s) it will depart from the packet switch. (It may optionally decide whether it should be forwarded, and what quality of service it should receive),
(2) "How" (Interconnection Fabric/Switching) --- The packet switch must then deliver the packet across a backplane or through an interconnection fabric to the selected outgoing port(s).
(3) "When" (Output link scheduling) --- Finally, the packet switch must decide when the packet departs.

In this tutorial, we will review the basic properties of packet-switches, go through each of the three stages outlined above, describing how they are performed in LAN switches, ATM switches and IP Routers. We will explain the main research results, and underlying theory in each area.
We will then make some (wild) predictions about what's coming next..

Required Background:
A good understanding of IP and Ethernet, such as provided by an introductory course or textbook. A basic understanding of ATM would be useful.

Biography:
Nick McKeown is an Assistant Professor of Electrical Engineering and Computer Science at Stanford University. He received his Phd from the University of California at Berkeley in 1995. From 1986-1989 he worked for Hewlett-Packard Labs, in their network and communications research group in Bristol, England. During the Spring of 1995, he worked briefly for Cisco Systems where he helped architect the GSR 12000 router. Nick is a Senior Member of the IEEE, serves as an Editor for the IEEE Transactions on Communications, is the Robert Noyce Faculty Fellow at Stanford, and recipient of a fellowship from the Alfred P. Sloan Foundation. Nick is currently on leave from Stanford at Abrizio Inc.
