Content-based switch system, and content-based switching method

摘要

There is a problem that in a routing process based on the content of the communication, either switching to browse the contents for each switch in the path, using the routing label is required, it will not perform efficient processing. To solve this problem, passed to the network controller Contents by terminating the relay station data from the source terminal, allocates the flow information required for relaying, the network controller is a flow transfer instruction to switch setting. Flow information assigned is notified to the relay apparatus, the relay apparatus sets the communication flow to the destination terminal by using the flow information is given, and relays the data to the destination terminal from the source terminal.
