Abstract
There is provided a transmission system which realizes more flexible resource allocation. A resource management means upon receipt of a resource allocation request including a minimum bandwidth and a maximum bandwidth, reduces allocated resources stored in an allocated-resource request table to the corresponding minimum bandwidths. As such, the request is accepted with higher probability. When releasing an allocated resource, the resource management means increases the allocated-resources of the allocated-resource requests to bandwidths within a range of the corresponding maximum bandwidths. Accordingly, the resources are utilized more effectively. When releasing the resource, the resource management means notifies, by broadcast, all the communication apparatuses that free resources are increased. Thus, for the communication apparatus whose request has been rejected, the resource is allocatable.
