Problems solved by technology

However, in the VxLAN forwarding of the prior art, the packet sent by the source virtual machine needs to go through multiple table lookups and the processing of IP in protocol stack and IP out protocol stack before it can be received by the destination virtual machine, the implementation process is complicated, thereby reducing packet forwarding efficiency

Abstract

The embodiments of the present invention propose a method and device for forwarding virtual extensible local area network (VxLAN) messages. The method is applied to a first virtualized OpenFlow switch (OVS), and includes: receiving a flow entry from a software-defined network (SDN) controller, the flow entry carrying VxLAN message address information and the first OVS on the first Uplink (Uplink) port, the flow entry is used to send the original message received from the source virtual machine hanging on the first OVS and the destination virtual machine hanging on the second OVS to the first A first VxLAN port on the OVS, and the first VxLAN port adds a VxLAN header containing the VxLAN message address information to the original message to form a VxLAN message, and is used to send the VxLAN message through the first Uplink port.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of network communication, in particular to a method and device for forwarding virtual extensible local area network (Virtual Extensible Local Area Network, VxLAN) messages. Background technique [0002] Software Defined Network (SDN) technology realizes flexible control of network traffic by separating the control plane and data plane of network devices. Correspondingly, the SDN architecture includes an SDN controller and an SDN switch, wherein: the SDN controller and the SDN switch communicate through an SDN management channel that is preferably an OpenFlow (OpenFlow) protocol, and the SDN controller operates according to user configuration or dynamically The flow table generated by the protocol is delivered to the SDN switch, and the SDN switch processes the message according to the flow table delivered by the SDN controller. [0003] VxLAN is a technology that encapsulates Layer...
