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.

Network communication method based on software-defined networking and server using the method

A network equipment is in communication with customer premises equipment (CPE) through a primary electrical path and a secondary electrical path, and includes a timer, a processor and a switching device. The timer provides heartbeat packets for the CPE via the primary electrical path and the secondary electrical path to obtain a first response time and a second response time corresponding to the primary and secondary electrical paths. The switching device is switched to the primary electrical path or the secondary path under the control of the processor. When the timer reaches a preset retransmission timeout, the processor controls the switching device to be switched to the secondary electrical path from the primary electrical path. When the second response time exceeds the first response time at least twice in succession, the processor enables the switching device to be selectively switched to the primary electrical path.

Network equipment and method for selecting communication path

A data transmission management server for managing a terminal device to access a network resource providing server by a source gateway in a virtual private network (VPN) obtains current resource information of a plurality of gateways in the VPN periodically. The data transmission management server selects one from the gateways as a destination gateway according to the resource information, transmits an internet protocol address of the destination gateway to the source gateway to make the source gateway establish a secure communication tunnel to the selected destination gateway and access the network resource providing server over the secure communication tunnel.
