Problems solved by technology

[0003] However, in this data flow forwarding method, the forwarding device calculates the forwarding route of the data flow according to the five-tuple hop by hop and forwards it. Each forwarding device cannot determine the data flow forwarding route based on the global view of the network, so the Determined lack of flexibility and poor utilization of network resources

Embodiment Construction

[0066] In recent years, software-defined network (SDN, Software defined network) technology has developed rapidly, and the application of SDN technology in environments such as data centers, enterprise networks, and campus networks is the key implementation scenario of current SDN research. With the development of SDN technology, network technology is gradually evolving from distributed / discrete management to logically centralized. In a network environment where SDN technology is applied, the logic control center has a global view of the network, and can dynamically perceive network equipment, link status, user priority, service response requirements, network load and delay, etc., and based on this dynamic perception Make the best decisions. The above advantages of SDN can bring new vitality to the routing algorithm.

[0067] At present, in terms of SDN network architecture, it tends to separate the functions of the logic control center or network operating system (NOS, Netwo...

Abstract

Embodiments of the present invention provide a control method and apparatus for the data stream forwarding route. The parameter information of each data stream and the logical topology of a network used by the method are pre-stored. The method also includes: receiving a forwarding request of the first data stream transmitted by a network device; obtaining the parameter information of the first data stream from the pre-stored parameter information of each data stream; determining the forwarding policy of the first data stream according to the parameter information; the forwarding policy including the quintuple and other communication information of the first data stream; determining the forwarding route of the first data stream in the network according to the forwarding policy of the first data stream and the logical topology of the network; transmitting the forwarding route of the first data stream in the network to the network device. The embodiments of the present invention can improve the flexibility of the forwarding route determination and the network resource utilization ratio.

Description

technical field [0001] The invention relates to the field of communication, in particular to a control method and device for forwarding and routing of data streams. Background technique [0002] When forwarding the data flow, the traditional routing scheme of the five-tuple mode is generally used at present. The five-tuple includes: source address, destination address, source port, destination port and protocol number of the data flow. Specifically, the forwarding device in the network uses the quintuple as the routing reference object, and calculates the route of the data flow hop by hop through the network protocol corresponding to the protocol number, so that the final data flow starts from the source port of the source device indicated by the source address and is forwarded The device forwards hop by hop, and finally reaches the destination device indicated by the destination address through the destination port. [0003] However, in this data flow forwarding method, t...
