Abstract:
An SDN-enabled network communication method is disclosed. A master TURN server sends a client an error response and assigns a relay switch as a backup server for the client using an alternate-server mechanism. Therefore, data streams of the client are directly transferred to the relay switch. With support by a shadow TURN server and an SDN controller, switches forwarding the data streams are managed according to the OpenFlow protocol to implement path optimization for the data streams.

Claim (Index 1):
A computer-implemented method, executed by a master Traversal Using Relays around Network Address Translation (TURN) server, the method comprising:\n receiving an allocation request from a client; determining whether the client belongs to a preset category; selecting one of a plurality of forwarding devices as the relay device via a Software-Defined Networking (SDN) controller if the client belongs to the preset category; assigning a first Internet Protocol (IP) address and an access port to the client according to the allocation request; instructing the SDN controller to define forwarding rules for the relay device; replying a second error response to the client; and enabling the client to deliver the allocation request to the relay device, the relay device to forward the allocation request to the SDN controller according to the forwarding rules, and the SDN controller to forward the allocation request to a shadow TURN server.
