Performing compression includes receiving at a compressor a flow comprising packets, where each packet has a packet identifier. The packet identifiers are associated with a predetermined increment, but any change in the predetermined increment is ignored. The packets are compressed, and the flow is transmitted to a decompressor.

What is claimed is: 1. A method for performing compression, comprising: receiving at a compressor a flow comprising a plurality of packets, each packet having a packet identifier, the packet identifiers associated with a predetermined increment; ignoring a change in the predetermined increment associated with the packet identifiers; compressing the plurality of packets; transmitting the flow to a decompressor; and determining that an inactive time associated with the flow has exceeded a maximum allowed inactivity period, the flow having a context identifier. 2. The method of claim 1, further comprising: receiving the flow at the decompressor, each packet of the flow having a sequence number; detecting a skip in the sequence numbers of the plurality of packets of the flow; and accepting the flow having the skip in the sequence numbers. 3.

The method of claim 1, further comprising: determining at the compressor that a previous inactive time of a previous flow has exceeded a previous maximum allowed inactivity period, the previous flow associated with a context identifier; establishing that the context identifier is available; and assigning the context identifier to the flow in response to establishing that the context identifier is available. 5. The method of claim 1, further comprising: determining at the compressor that a previous inactive time of a previous flow has exceeded a previous maximum allowed inactivity period, the previous flow associated with a context identifier, the previous inactive time exceeding the previous maximum allowed inactivity period prior to exceeding an expiration period; and establishing that the context identifier is available. 6.
