Embodiment Construction

[0067] Under the new OpenFlow protocol architecture, the forwarding plane cannot make corresponding assumptions about business scenarios, so there is a problem that the load sharing algorithm cannot be determined. In particular, due to the existence of business models such as meter tables, improper design of the load sharing algorithm may cause the business to fail.

[0068] In order to solve the above problems, an embodiment of the present invention provides a distribution method, an OpenFlow switch, a controller and a distribution system. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0069] First, Embodiment 1 of the present invention will be described with reference to the accompanying drawings.

[0070] The embodiment of the...

Abstract

The invention provides a shunting method, an OpenFlow switch, a controller and a shunting system, and relates to the communication field, being able to solve the problem of being short of a load sharing system under a new OpenFlow protocol framework. The shunting method includes the steps that an OpenFlow switch sends the switch configuration attribute to a controller, wherein the switch configuration attribute carries a shunting characteristic parameter which shows that the OpenFlow switch supports shunting; the OpenFlow switch receives shunting configuration issued from the controller; and according to the shunting configuration, the OpenFlow switch shunts the flow arrives in the OpenFlow switch to different forward entities. The shunting method, the OpenFlow switch, the controller and the shunting system are suitable for a new OpenFlow protocol framework network, and can realize load sharing under the new OpenFlow protocol framework.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a distribution method under the OpenFlow protocol, an OpenFlow switch, a controller and a distribution system. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a new network innovation architecture. The OpenFlow protocol adopted by the SDN network separates the network device control plane (including the OpenFlow controller Controller) from the data plane (including the OpenFlow switch CapableSwitch), thereby realizing flexible control of network traffic and providing innovations for core networks and applications. good platform. [0003] The OpenFlow protocol is used to describe the standard of information used for the interaction between the controller and the switch, as well as the interface standard of the controller and the switch. The core part of the protocol is a collection of information structures for the OpenFlow protocol....
