Relay apparatus and relay method suitable for performing communication to ensure quality of service

摘要

A detecting section monitors predetermined information included in communication contents transmitted from one node of two communication nodes to detect bandwidth information associated with a required bandwidth for transmitting the communication contents from one node of the two communication nodes to the other node. A bandwidth allocating section makes a determination on whether or not the required bandwidth can be guaranteed based on the bandwidth information detected by the detecting section, and allocates the buffer sections capable of guaranteeing the required bandwidth of a buffer group to the communication contents when determination is that the required bandwidth can be guaranteed.
