A virtual machine data forwarding method, sdn controller and sdn system

Abstract

The invention discloses a virtual machine data forwarding method, an SDN controller and an SDN system. The method comprises: the SDN controller receives a virtual machine data packet sent by a forwarding device, and the SDN controller judges the target based on the IP address of the target virtual machine Whether the virtual machine is a virtual machine in this network, if so, obtain the virtual machine identification code corresponding to the IP address of the target virtual machine, and obtain the IP information of the physical machine where the target virtual machine corresponding to the virtual machine identification code is located; SDN The controller performs route selection according to the IP information of the physical machine, and sends the routing information to the physical machine to the forwarding device. The forwarding method, SDN controller and SDN of the present invention select routes based on the IP information of the physical machine, reduce the complexity of route search, and realize the integration of computing, network and storage resources more effectively through collaboration with the cloud management platform Manage and orchestrate resources to improve resource utilization and cloud service capabilities.

Description

technical field [0001] The invention relates to the technical field of data transmission, and in particular, to a method for forwarding virtual machine data, an SDN controller and an SDN system. Background technique [0002] Software Defined Network (SDN) is a new innovative network architecture. With the widespread application of virtualization technology, IT resources will become operational infrastructure like water and electricity. Cloud data centers are the carriers of important cloud infrastructure. With new automation and self-service requirements such as perception, vlan isolation, and multi-tenant isolation, its virtual machine communication has become an important research topic, and SDN is characterized by its centralized control, control, and forwarding. One of the main solutions for data center networking. [0003] In order to solve the problems of large layer 2 environment, insufficient VLAN, multi-tenant isolation and other problems faced by data centers, VM...
