This memo discusses a proposed extension to the Internet architecture and protocols to provide integrated services, i.e., to support realtime as well as the current non-real-time service of IP. This extension is necessary to meet the growing need for real-time service for a variety of new applications, including teleconferencing, remote seminars, telescience, and distributed simulation. This memo represents the direct product of recent work by Dave Clark, Scott Shenker, Lixia Zhang, Deborah Estrin, Sugih Jamin, John Wroclawski, Shai Herzog, and Bob Braden, and indirectly draws upon the work of many others.
