Embodiment Construction

[0031] A typical SDN network architecture includes SDN switches and SDN controllers. The SDN controller can directly access and control the SDN switch of the forwarding plane through a proprietary protocol, such as the Open Flow protocol, through the Open Flow channel. The OpenFlow channel provides a relatively rigorous TCP (Transmission Control Protocol, Transmission Control Protocol) connection channel. Most commands issued by the SDN controller can require the peer SDN switch to return the execution result.

[0032] The current Open Flow channel does not support a command cancellation mechanism. For example: the SDN controller sends a flow table query command to the SDN switch, and the SDN switch executes the query operation after receiving the command, and returns the query result to the SDN controller. When the SDN controller issues multiple commands, the SDN switch executes each command in turn, and will not execute the next command until the previous command is execute...

Abstract

The invention provides a method and device for controlling an SDN switch. The method comprises the steps that a command termination message issued by an SDN controller is received, wherein a command serial number is carried in the command termination message; whether the execution of a command is completed or not is inquired according to the command serial number; when the execution of the command is not completed, the command is terminated, and a termination success message is returned to the SDN controller, wherein the command serial number is carried in the termination success message. According to the technical scheme, the processing efficiency of the SDN switch to the command is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a control method and device for an SDN switch. Background technique [0002] With the continuous development of Internet services, the time required for Internet services to be deployed on the Internet is getting shorter and shorter. For example, a few years ago, a service deployment often took several months and required a lot of manpower. Now an Internet business may require deployment within a few days with a small amount of manpower. How to quickly deploy an Internet service involves some new technologies, such as SDN (Software Defined Network, software-defined network) technology. Under the model defined by SDN, service deployment can be realized through software, thereby reducing manpower Invest in and shorten the construction period. [0003] SDN is a new type of network innovation architecture. It adopts a brand-new design concept to separate the control ...
