Compressing TCP/IP Headers for Low-Speed Serial Links
Overview
RFC 1144, “Compressing TCP/IP Headers for Low-Speed Serial Links”, is a Proposed Standard document published in February 1990 by V. Jacobson. The canonical text is published by the RFC Editor.
Abstract
This RFC describes a method for compressing the headers of TCP/IP datagrams to improve performance over low speed serial links. The motivation, implementation and performance of the method are described. C code for a sample implementation is given for reference. [STANDARDS-TRACK]
