Header compression system for compressing the header of the data packets of a flow transmitted from an ingress node to an egress node through a data transmission network comprising template creating means, in both ingress node and egress node, adapted for creating the same compression template from a predetermined number of uncompressed data packets at the beginning of the flow respectively transmitted by the ingress node and received by the egress node, and header compression means, in the ingress node, adapted for compressing the header of each packet following the predetermined number of uncompressed data packets before transmitting it through the data transmission network, the compression being achieved by using the compression template.

The invention claimed is: 1. A system for compressing a header of a plurality of data packets of a flow transmitted through a data transmission network, comprising:an ingress node and an egress node;wherein the ingress node is configured to:perform a flow lookup comprising determining if an existing compression template matches an address associated with the flow in a template and label table;create a new compression template in the template and label table from a predetermined number of uncompressed data packets at a beginning of the flow respectively transmitted by the ingress node and received by the egress node, wherein the new compression template is identical in the ingress node and the egress node, wherein the new compression template is created if the existing compression template is not found by the ingress node in performing the flow lookup; andcompress a header of each packet of the plurality of data packets following the predetermined number of uncompressed data packets before transmitting the plurality of data packets through the data transmission network, wherein the ingress node compresses the header of each packet by using the new compression template.
