Abstract

This memo defines the Internet Stream Protocol, Version 2 (ST-II), an IP-layer protocol that provides end-to-end guaranteed service across an internet. This specification obsoletes IEN 119 "ST - A Proposed Internet Stream Protocol" written by Jim Forgie in 1979, the previous specification of ST. ST-II is not compatible with Version 1 of the protocol, but maintains much of the architecture and philosophy of that version. It is intended to fill in some of the areas left unaddressed, to make it easier to implement, and to support a wider range of applications.
