Abstract
A device (D1) for compression of streams of packets of data, for a communication equipment (E1) constituting a transmission end point in an Internet Protocol communication network (R), the packets of a stream each comprising, in particular, an IP header including a destination end point (E2) identifier, a session identifier and stream attributes, and said packets being intended to be transmitted after decomposition into cells. This compression device (D1) comprises processing means (MT1) responsible, if they receive a packet of a stream, for determining if the IP header of the packet can be compressed as a function of at least one chosen criterion, and for determining if the compression can lead to a reduction in the number of cells having to result from the decomposition of that packet.
