Panel: Global Routing System Scaling Issues

Cathy Wittbrodt, iVMG, moderator

Abha Ahuja, Arbor Networks
Tony Li, Procket Networks
Vijay Gill, MFN
Enke Chen, Redback


With the rapid growth of the Internet routing table, providers are experiencing difficulty maintaining network stability, even with aggressive filtering policies in place. This panel will discuss the causes of routing prefix table growth, measures providers should take to curtail it, and alternate measures enterprises and service preoviders can take to ensure redundancy and load-balancing without announcing their prefixes into the global table.

About the Presenters
Cathy Wittbrodt is VP for Architecture at iVMG. Prior to joining iVMG she was with Excite@Home, where she was responsible for network routing and IP addressing. Cathy is a member of the ARIN advisory council as well as the Address Supporting Organization (ASO) address council. She has been active in the Internet for 12 years. She began at Merit Network, Inc. where she worked on the NSFNET Backbone. Also while at Merit Cathy built CICNet, a network that connected the Big 10 universities. Following Merit, Cathy designed and implemented OSI/CLNP for the Energy Sciences Network. Although OSI/CLNP was never widely deployed, the experience has given greater insight into addressing and scaling issues. Cathy also spent three years in the engineering group of the Bay Area Regional Research Network, BARRNet, which was bought by BBN Planet. Cathy is on the Board of Directors of Panzer Motorcycle Works, USA, Inc. She has a B.S. in mathematics from Northern Arizona University.
