Patent ID: 8885670

Claim:
A device for compression of streams of packets of data, for a communication equipment comprising a transmission end point in an Internet Protocol (IP) communication network, said packets of a stream each comprising an IP header including a destination end point identifier, a session identifier and stream attributes, and a transport protocol header, and said packets to be transmitted after decomposition into cells, the device comprising: a processing module configured, in case of reception of a packet of a stream, to: determine if the IP header of said packet can be compressed as a function of at least one chosen criterion, then if so, to determine if said compression can lead to a reduction in the number of cells having to result from the decomposition of said packet, and if so, to replace in said packet at least said IP header by a compressed header comprising at least the session identifier and a compression identifier, after having transmitted beforehand to said destination end point of the received stream, in a partially compressed form, at least the IP header that has to be replaced; and in case of replacement of at least the IP header of a received packet by an at least partially compressed header, determine if the payload data associated with the at least partially compressed header can be compressed as a function of at least one chosen criterion, and if so, to integrate into the at least partially compressed header an identifier signaling the data compression.
