Abstract

The invention discloses an extensible virtual local area network message transmission method, a device and a system, which can be applied to an open flow network. When an open flow switch receives a first message sent by a first virtual machine in the open flow network, a match of the first message is built according to the information of the first message; according to the match of the first message, a first flow table entry corresponding to the match of the first message is acquired; according to the first flow table entry, package of the extensible virtual local area network VXLAN is ensealed by the first message, and the packaged first message is sent to a second virtual machine; and the first virtual machine and the second virtual machine are located in different open flow switches or different physical machines. The problem that the existing OpenFlow network protocol does not fully support the VXLAN can be solved.

Description

technical field [0001] The embodiments of the present invention relate to the field of network technologies, and in particular to a method, device and system for transmitting scalable virtual local area network messages. Background technique [0002] OpenFlow technology enables more advanced traffic management through network access to the forwarding plane of switches or routers, especially in virtualized environments. The core idea of ​​OpenFlow is to transform the packet forwarding process that was originally completely controlled by the switch or router into an independent process completed by the OpenFlow Switch and the OpenFlow Controller. [0003] Virtual Extensible Local Area Network (VXLAN for short) is a technology that encapsulates Layer 2 packets with Layer 3 protocols. It can expand the Layer 2 network in the Layer 3 range so that virtual machines can communicate with each other Migrate within the scope of the three-tier network without changing the Internet Pro...
