Abstract
A communication resource management scheme capable of guaranteeing the communication quality with respect to the flow while not requiring the processing for each flow to nodes other than edge nodes is disclosed. The edge node stores an information for obtaining an available amount of communication resources that can be newly allocated in the network to one set of flows which share at least a route from that edge node to an egress node of the network. Then, the edge node carries out an admission control by newly receiving a request for allocation of communication resources for one flow belonging to that one set of flows, judging whether or not to accept the request according to a requested amount of communication resources and the available amount of communication resources as obtained from the information stored for that one set of flows, and allocating requested communication resources to that one flow when it is judged that the request is to be accepted, while the edge node and the core node carry out the priority control.
