Packet-Oriented Communication Using a Stream Protocol or Making TCP/IP on Berkley Unix a Little More Pleasant to Use

摘要

The only DoD protocols supporting the Transport Layer in the OSI Model are UDP and TCP. UDP is packet-oriented while TCP is stream-oriented. It is often useful to mix characteristics of both. The paper describes a software package that stimulates the useful properties of UDP while using TCP. Also included are some functions for easier establishment of connections than by using TCP/IP primitives. In addition, some observations gained during the experience of implementing this on a 4.2BSD UNIX system are described.
