Abstract

The invention relates to an SDN controller implementation method. The SDN controller implementation method includes the steps that service flow information sent by an SP is received, wherein the service flow information includes flow labels of service flow; requests, for establishing VNs, sent by the SP are received, the requests are selected according to a preset access strategy and a preset grade standard, and then the target request is determined, wherein the requests carry node resource information and link resource information; according to the flow labels, resource instantiation is conducted on the service flow, and the VNs meeting the target request are generated; according to the instantiation requirements of the VNs and the VR supply status, a mapping scheme is generated; according to the mapping scheme, resource control instructions are sent to VR in the mapping scheme, and the VR is deployed.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a method for realizing an SDN controller and an SDN controller. Background technique [0002] With the improvement of terminal computing and processing capabilities and the expansion of network transmission capabilities, the information carried by the network has expanded rapidly. The Internet is no longer a network purely for communication, but more towards meeting people's needs for information. , to become a platform for carrying and distributing information. Due to people's diverse demands on information acquisition methods (wired, mobile), information types (data, voice, video), information quality, information security, etc., the Internet continuously introduces a large number of control protocols in order to adapt to and meet various needs. , forming a huge control plane. These control protocols are designed to be attached to a specific forwarding protocol, and from the ...
