Tutorial: VoIP Peering

Jon Peterson, Neustar
Presentation Date: June 15, 2009, 4:30 PM - 6:00 PM

Room: Commonwealth A/B, 2nd FL

Abstract:
While various forms of application-layer peering overlays have long existed on the Internet to support applications like email and newsgroups, Voice over IP (VoIP) peering brings with it a new set of elements, policies, and challenges. This tutorial begins with the fundamentals, exploring why peering is even necessary for a largely client-driven application like VoIP. It then surveys the functional elements necessary to peer between telephony-replacing deployments, using the ongoing IETF work on VoIP peering as a touchstone. All of this is considered with a mind to the ongoing evolution of traditional voice services, including mobile telephony, and the rise of other client-driven Internet applications including instant messaging and peer-to-peer file sharing.
