DETERMINISTIC TUNNEL FOR QOS MANAGEMENT IN PACKET-SWITCHED NETWORK

This invention relates to an emitting node (N1) of a packet-switched network having forwarding resources to emit an output dataflow (DT) to a receiving node (N4) through said packet-switched network, said output dataflow being made of a sequence of output datagrams, and said emitting node being char...

Beschreibung
Zusammenfassung:	This invention relates to an emitting node (N1) of a packet-switched network having forwarding resources to emit an output dataflow (DT) to a receiving node (N4) through said packet-switched network, said output dataflow being made of a sequence of output datagrams, and said emitting node being characterized in that it is adapted - for determining for each of said output datagrams, emission dates corresponding to available windows of the forwarding resources of each nodes (N1, N2, N3) of a predetermined path between said emitting and receiving nodes, so as to constitute a coherent flow between said emitting and receiving nodes, and, - for scheduling input datagrams corresponding to input dataflows (F1, F2, F3, F4), each input dataflow being associated with a requirement of quality of service, to said output dataflow (DT) according to said requirements.
