Problems solved by technology

For large data centers, such a traffic model is not suitable for expansion, because as the traffic between different VMs increases, the number of flow entries will also increase, thereby exceeding the three-state content addressable memory (TCAM: Ternary Content Addressable) in the OpenFlow switch.

Embodiment Construction

[0056] In order to make the purpose, technical solution and advantages of the present invention more clear, the 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.

[0057] Such as figure 2 As shown, the software-defined network in this embodiment includes the OpenStack network node 1 and the OpenStack computing node 2 in the OpenStack cloud management platform, and the OpenFlow controller 3 and the OpenFlow switch 4. Each node can communicate with each other.

[0058] The OpenFlow control method applied to the above-mentioned network in this embodiment is as follows: image 3 shown, including:

[0059] Step 110, when the OpenStack network node creates a user network, establish and save the mapping relationship between the user networ...

Abstract

The invention relates to an OpenFlow control method and a corresponding insert, a platform and a network thereof. The method comprises the steps that mapping relationships between a user network and virtual local area networks as well as switch ports are built and stored according to the needs of building a network when OpenStack network nodes create the user network, in the mapping relationships, the user network corresponds to one or a plurality of virtual local area networks, and one virtual local area network corresponds to a plurality of switch ports; OpenStack calculation nodes synchronously store the mapping relationships in the OpenStack network nodes in an OpenFlow controller; the OpenFlow controller stores the synchronous mapping relationships of the OpenStack calculation nodes to generate a flow table and send the flow table to OpenFlow switches, and each virtual local area network in the mapping relationships is associated with one flow table item in the flow table. The invention further provides an OpenFlow controller insert, an OpenStack cloud management platform and a software defined network, and the quantity of flow table items is greatly reduced to be beneficial for system expansion through the binding of the virtual local area network and the flow table items.

Description

technical field [0001] The present invention relates to network technology, and more specifically, to an OpenFlow control method, a corresponding OpenFlow controller plug-in, an OpenStack cloud management platform, and a software-defined network based on the OpenStack cloud management platform. Background technique [0002] OpenStack is a cloud platform management project jointly initiated by NASA and Rackspace in 2010. It is also an open source project that aims to provide software for the construction and management of public and private clouds. The latest version is the 7th release - Grizzly. The primary task of the OpenStack project is to simplify the cloud deployment process and bring good scalability to it, so as to create a cloud computing platform that is easy to deploy, rich in functions, and easy to expand. OpenStack and OpenFlow currently have no common Chinese translations. [0003] OpenStack consists of multiple relatively independent service components, inclu...
