Problems solved by technology

[0005] However, at present, the encryption and decryption of packets can only be statically configured by the user on the VTEP. When there are many VXLAN tunnels, each VTEP device needs to configure encryption for multiple VXLAN tunnels. For example, if there are 3 VTEP devices, each VTEP If there are 1,000 VXLAN tunnels on the device, each VTEP device must be configured 1,000 times. The configuration is complicated, which is not conducive to the deployment of the entire SDN network and the encryption control of user packets on the tunnel.

Abstract

The application provides a message processing method based on a virtual extensible local area network (VXLAN) tunnel and a message processing device. The message processing method is applied to two switches for building the VXLAN tunnel. The message processing method comprises the steps that: respective port status messages are reported to a controller after building the VXLAN tunnel, wherein the port status messages carry tunnel information and the tunnel information includes encryption capability information, so that the controller can return a port modification message carrying an encryption information to the two switches when the tunnel information reported to the two switches are confirmed to be consistent and at least part of a supported encryption algorithm is the same; and the port modification message is received, the encryption information is analyzed from the port modification message; the message of the VXLAN tunnel is encrypted according to the encryption information or the message output from the VXLAN tunnel is decrypted. According to the embodiments of the application, the message processing method and the message processing device can avoid a static configuration of the user on a VXLAN tunneling end point (VTEP) and can realize a flexible encryption control of the user message on the tunnel to the controller.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a message processing method and device based on a virtual extensible local area network (VXLAN) tunnel. Background technique [0002] With the rapid development of network technology, a new type of network architecture Software Defined Network (Software Defined Network, SDN) came into being. Its core idea is to separate the control plane of network equipment from the forwarding plane, so as to realize the flexibility of network traffic. control. [0003] In an SDN network, Openflow switches are interconnected by virtual tunnels, and the virtual tunnels are maintained by Virtual eXtensible Local Area Network (VXLAN). The controller does not need to calculate the network topology or pay attention to the devices. The forwarding path and state of the tunnel between them. When the hosts need to pass through the VXLAN network, the controller specifies the action item in the...
