Method and switcher for achieving message forwarding of virtual machine

Abstract

The embodiment of the invention provides a method for achieving the message forwarding of a virtual machine, and the method comprises the steps: receiving a first message which is sent by a first virtual machine on a first server and comprises the identification of the first virtual machine and the identification of a virtual network where the first virtual machine belongs; building a first channel according to the identification of the first virtual machine and the identification of the virtual network where the first virtual machine belongs in the first message, enabling a port connected with a gateway sever and a port connected with the first server to be added to the first channel, and learning the identification of the first virtual machine at the port connected with the first server; and transmitting a data message transmitted by the first virtual machine through the port, connected with the gateway server, in the first channel. Meanwhile, the embodiment of the invention also provides a switcher for achieving the message forwarding of the virtual machine. The method and switcher reduce the complexity of operation and maintenance of a data center network, improve the flexibility of the network, and achieve the automatic butt joint of a physical network and a virtual network.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and a switch for realizing message forwarding of a virtual machine. Background technique [0002] The purpose of system virtualization is to virtualize and run one or more virtual machines (Virtual Machine, VM for short) on a physical machine by using a virtualization manager (Virtual Machine Monitor, referred to as VMM). A logical computer system running in an isolated environment with complete hardware capabilities, including guest operating systems and applications within them. [0003] A virtual network refers to a virtual network path composed of virtual network devices such as virtual switches and virtual routers running on the Hypervisor layer in a virtualized server. The physical network corresponding to the virtual network is a physical network path composed of physical network devices such as switch hardware devices and router hardware devices. [0004] A...

Problems solved by technology

The problem with this approach is that any Layer 2 message will be forwarded on all access switches, and the Layer 2 broadcast domain will expand to the entire data center network

[0009] 2) When the virtual machine needs to be migrated, the administrator adds the corresponding network configuration (such as VLAN) to the target network. This manual configuration method is prone to omissions and the workload is complicated. It is generally operated by different departments, which also involves the tacit cooperation of the two departments, so it is difficult to ensure that the business will not be interrupted during the migration
