This publication describes a method to reduce the probability of degrading TCP data application throughput for systems employing TCP/IP Header Compression with PPP in a wireless environment. TCP performance can be severely impacted when Van Jacobson Compression (RFC 1144) is employed in a wireless environment where the probability to lose TCP segments can be substantial at times. The mechanism described to avoid this condition is an enable/disable of TCP/IP header compression between PPP peers based upon a trigger that monitors RF trends that predict an increased probability to lose TCP segments such as poor RF quality.
