A device (D) for compression of streams of packets of data, for a communication equipment (E) 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 (E) identifier, a session identifier and stream attributes, and said packets being intended to be transmitted after decomposition into cells. This compression device (D) comprises processing means (MT) 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.

Compression device wherein compression is adapted as a function of the transport medium, and associated decompression device, for communication equipments
