Gigascope: Building a Gigabit Network Sniffer

In this talk I will present a overview of the Gigascope project. Gigascope is a fast and flexible next-generation packet sniffer currently under development at AT&T Labs-Research. Gigascope's high-level goal is to help network managers/operators diagnose problems and monitor usage on networks as they get faster and carry more complex and demanding application traffic. Gigascope currently supports link rates up to OC48 speed (2.45 Gpbs). Gigascope's key unique features include: a highly flexible SQL-like query interface that enables rapid development of new queries, the ability to collect high-level packet data at gigabit speeds in real-time, and the ability to filter, transform, and aggregate data at multiple levels (even within the firmware of a network interface card). In the talk I will describe the Gigascope architecture, how it functions, and how it can be deployed within a network.

Chuck Cranor is a senior technical staff member in the Internet and Networking Systems Research Lab at AT&T Labs-Research in Florham Park, NJ. He received his B.S. in Electrical Engineering from the University of Delaware, and M.S. and D.Sc. in Computer Science from Washington University in St. Louis, Missouri. His technical interests include operating systems, high-speed internetworking, embedded systems, and secure systems. Chuck is also a contributor to the open source BSD operating systems projects, having written the BSD UVM virtual memory system, developed the BSD ATM networking framework, and ported NetBSD to previously unsupported platforms.
