Problems solved by technology

[0006] In the prior art, after the GW is selected for forwarding according to the hash algorithm, the traffic sharing will be uneven. For example, the traffic forwarded by some gateway ports exceeds the forwarding limit and causes traffic congestion, while other GW ports are idle. Packet loss is caused, and the overall operating speed of the system is low, which has a great impact on the entire network

Embodiment Construction

[0052] In the prior art, after the GW is selected for forwarding according to the hash algorithm, the forwarding traffic of the port of the gateway exceeds the forwarding limit and the message is blocked, while the other GW ports are idle, the embodiment of the present invention monitors the traffic of the gateway port, and Obtain the port type. When the traffic of the port reaches the maximum forwarding capacity of the port, the controller obtains the traffic information of the port, and migrates the traffic of the port to other idle ports according to the traffic information and the port type. Ports solve the problem of gateway port traffic congestion, dynamically adjust port traffic, and make the entire network more secure and reliable.

[0053] The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Apparently, the described embodiments are part of the embodiments of this application, n...

Abstract

The present invention discloses a flow sharing method and equipment. The method comprises that: a controller monitors the flow conditions of ports of multiple gateways and obtains the types of all the ports; when it is detected that the flow of some port reaches a specified threshold value, the controller obtains the flow information of the flow of the port according to a flow table of the port; the controller determines the flow to be migrated and a target port according to the flow information and the port type, and migrates the flow to be migrated to the target port. The method solves the port flow congestion of the gateways, realizes dynamic adjustment of the port flow, and enables the whole network to be safer and more reliable.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a flow sharing method and equipment. Background technique [0002] SDN (Software Defined Network, software-defined network) is a new type of network architecture. The VCF (Virtual Converged Framework, virtual application fusion architecture) controller is an SDN controller launched by H3C, which supports the standard OpenFlow protocol. The OpenFlow protocol is used as the control The communication interface standard between the controller and the forwarding layer allows the controller to directly access and operate the forwarding plane of network devices. These network devices can be physical switches supporting OpenFlow or virtual switches vSwitch. [0003] At present, the internal layout of large data centers adopts the layout of a large layer 2 network. In order to realize the communication between the large layer 2 network and the existing traditional layer 3 network, it...
