Problems solved by technology

[0009] The use of VLAN to implement multi-tenant virtual network has the following disadvantages: Ethernet packets need to carry VLAN tags, resulting in a relatively large packet load; IEEE802.1Q only supports 4K VLANs, which limits the expansion of virtual networks

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] In the embodiment of the present invention, the OpenFlow system architecture is used to deploy the multi-tenant distributed virtual network of the data center through the OpenFlow protocol. The system consists of a control server and an OpenFlow switch deployed on each server. The virtual network information is configured in the control server and the virtual network is managed by the control server.

[0031] see image 3 , image 3 is a schematic diagram of the system architecture of a distributed multi-tenant virtual network according to an embodiment of the present invention, as shown in image 3 As shown, the system includes an OpenFlow controller deployed on server 0, an OpenFlow switch deployed on server 1, and an OpenFlow ...

Abstract

A SDN controller receives a forwarding request message including a header portion of a layer-2packet. The SDN controller determines whether a source host and a destination host of the layer-2packet are in the same virtual network according to a virtual network table.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for realizing a distributed multi-tenant virtual network. Background technique [0002] The virtualization technology of the data center mainly includes three aspects: network virtualization, storage virtualization and server virtualization, the most important one is server virtualization. Through dedicated virtualization software (such as VMware) management, a physical server can virtualize multiple virtual machine VMs, each VM runs independently, does not affect each other, has its own operating system and applications and virtual hardware environment, Including virtual CPU, memory, storage device, IO device, virtual switch, etc. Among them, the virtual switch is increasingly widely used. [0003] At present, the edge virtual bridging technology EVB has been applied in the virtual switch. EVB technology is divided into switch EVB tech...
