Embodiment 1

[0035] Such as figure 1 As shown, the SDN architecture based on network virtualization in this embodiment includes: cloud service platform, network virtualization equipment, computing virtualization equipment, and storage virtualization equipment. The cloud server bottle is used as the central control system, and the client is used for computing, Network and storage requirements are sent to the cloud server, which is uniformly allocated and managed by the cloud service platform.

[0036] The computing virtualization equipment adopts H3C's computing virtualization platform, the cloud service platform adopts H3C cloud platform management system, and the network virtualization equipment adopts H3C's SDN controller. The SDN controller manages network devices. A storage virtualization device includes a virtual storage controller (or a storage virtualization access device) and multiple physical storage implementations, and the virtual storage controller may be implemented in a serv...

Embodiment 2

[0041] Such as figure 2Shown is a schematic diagram of the hardware structure adopted by the architecture in this embodiment. As shown in the figure, it uses two S12500 core switches and three S6800 switches. The two S12500 core switches respectively control the three S6800 switches and the service network, and the three S6800 switches are connected to multiple servers. H3C's switch is a device using overlay technology. During the network establishment process, the automatic deployment of modules through the SDN network can complete the automatic establishment of the EVPN tunnel on the overlay network. The SDN controller is designed for dual-machine deployment to improve node reliability. The virtual machine dynamic migration can be realized through the SDN controller combined with the Overlay network, and the configuration can be automatically delivered according to the online status of the virtual machine, and the tunnel can be established automatically.

Abstract

The invention provides an SDN framework based on network virtualization. The SDN framework based on network virtualization comprises a cloud service platform, network virtualization equipment, computing virtualization equipment and storage virtualization equipment. A double-layer cloud service network framework is provided. When the user requires to perform data accessing, the user logs in the cloud service platform to perform accessing through his client side, and the cloud service platform provides the network access service for the user through the network virtualization equipment, providesthe computing service for the user through the computing virtualization equipment and meets the data access requirement of the user through the storage virtualization equipment according to the access demand of the user.

Description

technical field [0001] The invention relates to the communication field, in particular to an SDN architecture based on network virtualization. Background technique [0002] With the rapid expansion of enterprise business, IT is used as infrastructure, and its rapid deployment and high utilization rate become the main requirements. Cloud computing can provide available, convenient, and on-demand resources, and has become a regular form of current enterprise IT construction, and virtualization, which is widely adopted and deployed in cloud computing, has almost become a basic technical model. The deployment of virtual machines requires unlimited migration to the target physical location in the network. The rapid growth of virtual machines and the migration of virtual machines have become a normal business. The traditional network can no longer meet the business needs of enterprises, and the network part has become a bottleneck restricting the virtualization of the data center...
