OpenFlow communication method, system, controller and service gateway

Abstract

The invention discloses an open flow communication method, a controller, a virtual switch and a service gateway, which receive an action that needs to be transferred sent by the service gateway; select a suitable virtual switch according to the action that needs to be transferred and the network topology structure; Send the flow table with the virtual switch, and establish the first data channel between the service gateway and the virtual switch to forward the data packet; send the flow table with extended actions to the virtual switch to perform related extended actions on the data packet; The data packet after performing the relevant extended actions is sent to the destination server. Through the above disclosure, the present invention can transfer a part of data processing services from the service gateway to the virtual server for execution when the processing capability of the service gateway is insufficient, so as to realize the load balancing of each network element in the system and improve the utilization rate and throughput of the system , thereby improving the performance of the entire system.

Description

[0001] 【Technical field】 [0002] The invention relates to the communication field, in particular to an open flow communication method, system, controller and service gateway. [0003] 【Background technique】 [0004] With the globalization of the economy and society, more and more enterprises and institutions have established branches across the country or even around the world, and more and more employees on business trips access the business system of the headquarters in non-fixed locations. At the same time, with the continuous expansion of business and increasingly complex applications, the organization's IT (Information Technology, information technology) infrastructure is increasingly moving towards centralized management, and the establishment of data centers and cloud services has become the trend of IT construction. As the entrance of the data center and cloud service center, the enterprise service gateway's throughput directly affects the performance of the entire dat...

AI Technical Summary

Problems solved by technology

[0011] The existing enterprise business gateway serves as the entrance of the entire data center. When the amount of data to be processed exceeds its capacity, it becomes the bottleneck of the entire system, while a large number of computing resources of the back-end server are idle.
