Embodiment Construction

[0021] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other if there is no conflict.

[0022] The present invention provides an SDN-based cloud computing network virtualization implementation method, which includes the following steps:

[0023] The controller agent FlowVisor processes messages from the controller Controller and the Openflow switch respectively according to a preset strategy; wherein, the Openflow switch adopts the Openflow protocol through the communication between the controller agent and the controller.

[0024] Wherein, the Openflow protocol establishes a forwarding path from one VM to another VM in the cloud data center network, and establishes a two-layer broadcast domain based on the three-layer network between the VM and the VM.

[0025] Among them, the p...

Abstract

The invention provides a cloud computing network virtualization method and system based on an SDN, wherein the cloud computing network virtualization method and system are applied to the technical field of cloud computing. The method includes the following steps of processing information from a controller Controller and information from an Openflow interchanger through a controller proxy FlowVisor according to a preset strategy, wherein the Openflow interchanger is in communication with the controller proxy and the controller through Openflow protocols. According to the scheme, virtual network segments are dynamically configured for cloud service, and therefore a user network is as flexible as other cloud computing infrastructures, the data center automation degree and service flexibility are remarkably improved, VM density is increased, capital consumption and operating cost are reduced, limits of a traditional physical or regional isolation mechanism are eliminated, and the optimal VM density and the optimal economic benefits can be achieved through data center managers.

Description

Technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method and system for implementing cloud computing network virtualization based on SDN. Background technique [0002] The emergence of virtualization technology brings great economic benefits to data center users. Virtualization significantly shortens server deployment time, improves server utilization, improves service levels, and reduces capital expenditure and operating costs; however, virtualization technology brings every The change from 20 servers in a rack to 200 VMs per rack has brought new challenges to data center networks, including higher bandwidth and lower latency, increased server nodes and VM scales, and VM communication Management, Layer 2 interconnection between cross-data center sites to carry virtual machine migration, etc.; because of the insurmountable obstacles of traditional network architecture, users cannot realize the final network virtualization a...
