Methods for increased tolerance against packet reordering for the secure reference principle in robust header compression

摘要

A method for improving the use of a secure reference principle in a header compression scheme over a channel that admits reordering of packets between a compressor and a decompressor includes transmitting a first plurality of non-context updating packets between a compressor and a decompressor over the channel and, in response to a context update, transmitting a second plurality of context-updating packets between the compressor and the decompressor over the channel. The number of packets in the second plurality is greater than or equal to a maximum possible reordering that packets can experience on the channel between the compressor and the decompressor.
