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 ( ) (and/or decompressor) having an input that receives point to point packets ( ), such as original UDP packets, and an output that outputs compressed PPP packets ( ). The apparatus includes a PPP packet multiplexer (and/or demultiplexer) ( ) operatively coupled to the output of the PPP packet header compressor ( ), and operative to create a frame ( ) containing at least: multiplexed PPP packets from the plurality of PPP packets ( and ), PPP multiplexed identification data and PPP packet delimitation data ( ). 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 obtain separate PPP packets.
