METHOD FOR SUPPORTING ADMISSION CONTROL AND/OR PATH SELECTION IN A COMMUNICATION NETWORK

摘要

A method for supporting admission control and/or path selection in a communication network, said network including a plurality of wireless communication links, possibly of different link technologies, established between a plurality of network nodes, characterized in the steps of partitioning said communication links of said network into groups of communication links - link groups -, assigning each link group an associated link group controller that is configured to observe and/or measure the performance and/or quality of said link- group, based on said observations and/or measurements, computing estimates of metrics for the capacity of the respective link group and the costs for using each of the communication links of the respective link group, and transmitting said estimates to at least one resource management entity being configured to take admission control and/or path selection decisions on the basis of said estimates. Furthermore, a communication network with admission control and/or path selection supporting functionality is described.
