Abstract

A multiplexing scheme creates multiplexed PPP packets and demultiplexes the multiplexed PPP packets to reduce packet overhead. A point to point protocol packet communication apparatus such as a suitably programmed processing device or other suitable structure includes a point to point protocol packet header compressor (600) (and/or decompressor) having an input that receives point to point packets (601), such as original UDP packets, and an output that outputs compressed PPP packets (602). The apparatus includes a PPP packet multiplexer (and/or demultiplexer) (603) operatively coupled to the output of the PPP packet header compressor (600), and operative to create a frame (604) containing at least: multiplexed PPP packets from the plurality of PPP packets (606, 608 and 610), PPP multiplexed identification data 614 and PPP packet delimitation data (612). To demultiplex the multiplexed PPP packets at a receiving end, a method and apparatus includes evaluating PPP packet delimitation data from the frame containing multiplexed PPP packets, PPP multiplexed identification data and PPP packet delimitation data; and demultiplexing the frame based on the PPP packet delimitation data to obta…
