Packet Design is an Austin, Texas-based network performance management software company credited with pioneering Route Analytics technology. This network monitoring technology analyzes routing protocols and structures in meshed IP networks by participating as a peer in the network to passively “listen” to Layer 3 routing protocol exchanges between routers for the purpose of network discovery, mapping, real-time monitoring and routing diagnostics. The company maintains offices in San Jose, CA, Austin, TX, Dubai, UAE, and Beijing, CN. Packet Design, Inc. was co-founded in 2003, by Judy Estrin and Bill Carrico, notable network computing executives who have started seven companies together during their careers. Estrin served as CTO of Cisco Systems from 1998 to 2000, immediately prior to founding the company.
