John Scudder is a Distinguished Engineer at Juniper Networks. He began his career in network operations, working on the NSFNET at Merit Network, Inc, when he attended his first IETF (21, in Atlanta). Subsequently he has focused on routing protocol design and implementation, particularly though not solely BGP. He has, at various times, worked for a telco (Ameritech), co-founded a startup (IEng, or Internet Engineering Group), and worked for large vendors (Cisco, and now Juniper). Beyond routing protocols, his professional interests include system architecture.

John is a past co-chair of IDR, SPRING, and RTGWG, and a long-serving member of the Routing Directorate. He has co-authored a number of RFCs and patents. Outside of his professional life, his interests include cooking, bread baking, and (sadly neglected of late) yoga and scuba diving. He is based in Ann Arbor, Michigan, USA.
