Panel: Trends in Measurement and Monitoring of Internet Backbones
Meeting: NANOG26
Date / Time: 2002-10-29 10:40am - 12:00pm
Room: Hellman/Williams/O\'Neill
Presenters: Moderators:

David Meyer, Sprint/University of Oregon

David Meyer is currently Chief Technologist and Senior Scientist at Sprint. He is also Director of the Advanced Network Technology Center at the University of Oregon. Prior to working at Sprint, he worked at Cisco, where he was involved in software development, working both on multicast and BGP. He is active in the IETF, where he chairs the MBONED and MSDP (Multicast Source Discovery Protocol) working groups. He is also active in ANSI T1X1, among other industry organizations.
Panelists:

Chris Martin, Verizon

Christian Martin is Sr. Consulting Member of Technical Staff and Principal Network Architect at Verizon Internet Services, where he has worked for the past 5 years. Among his responsibilities is the overall design and technical implementation strategy of Verizon\'s IP network, where measurement is of critical concern. His interests are in network analysis and operations research on Internet networks, network modeling and simulation, and interdomain traffic analysis.

Christophe Diot, Sprintlabs

Christophe Diot received a Ph.D. degree in Computer Science from INP Grenoble in 1991. From 1993 to 1998, he was a research scientist at INRIA Sophia Antipolis, working on new Internet architectures and protocols. Diot moved to Sprint Advanced Technology Laboratory in October 1998 to lead the IP research group. His current interest is in the passive monitoring of the Sprint IP backbone in order to study IP traffic characteristics and to design new analytical models and traffic engineering solutions for pure packet networks. Diot is a member of IEEE and ACM, and serves as an editor for ACM/IEEE Transactions on Networking.

Jennifer Rexford, AT&T Research

Jennifer Rexford is a member of the IP Network Management and Performance department at AT&T Labs-Research in Florham Park, New Jersey. Her work focuses on routing protocols and traffic measurement, with a goal of developing new methods and tools for operating large IP networks. Jennifer received her BSE degree in electrical engineering from Princeton University in 1991, and her MSE and PhD degrees in Computer Science and Electrical Engineering from the University of Michigan in 1993 and 1996, respectively. She is a member of the editorial board of <I>IEEE/ACM Transactions on Networking</I> and is coauthor of the book <I>Web Protocols and Practice: HTTP/1.1, Networking Protocols, Caching, and Traffic Measurement</I> (Addison-Wesley, 2001) with Balachander Krishnamurthy
Mujahid Khan, Sprint.

Tony Tauber, Genuity

For the past eight years, Tony Tauber has worked at BBN, NEARnet, GTE Internetworking, and Genuity, in many roles from Operations to Engineering. Currently he is employed as a Network Architect at Genuity focusing on, among other things, OSS issues (including measurement support in network devices.) Additionally, Tony serves as co-chair of the IETF RPSec (Routing Protocol Security Requirements) Working Group. The product of a liberal arts eduction, he holds a Bachelor\'s degree in Religion and is sharpening his mystical powers to balance Technological capabilities, Engineering designs, Operational concerns and Business imperatives, all while getting the kids to school on time.
Abstract: Backbone operators are facing new requirements for backbone data collection and analysis. New services such as VPN and CoS-based services, as well as various security concerns, all contribute to new demands on monitoring, measurement, and analysis infrastructures. Combined with the desire for increasingly fine-grained analyses of both Operational Expenditures (OPEX) and Capital Expenditures (CAPEX), these new services have served to put a new importance and urgency on an operator\'s ability to measure and monitor network traffic.



This panel will explore the operational uses of measurement and monitoring in production Internet backbones. Questions include \"what kind of data is required (and how might we collect and analyze it) in order to facilitate various functions?\" such as:

  • Traffic engineering

  • Performance and SLA verification

  • DOS detection and mitigation

  • Forecasting and capacity planning




In addition, the panel will consider:

  • Sampling vs. accounting: requirements and methods

  • Convergence: IGP and EGP routing analysis

  • Operators\' wish list: What is missing from routers?

  • Overview of standards activities: Packet Sampling (psamp)

  • Working Group update
