IP NETWORK SERVICE QUALITY MANAGEMENT BY DISTRIBUTED ADMISSION CONTROL BASED ON A SIGNALLING PROTOCOL

摘要

Procedure and device for managing the quality of service hop-by-hop in a packet-based communications network comprising several arteries linked together by a router, the network supporting a signalling protocol. The procedure comprises at least at each router a step of reserving the resources on the arteries gradually and a step ensuring once the communication has been established that the packets of one and the same connection follow the path between the sending source and the destination on which the resources have been reserved.
