Problems solved by technology

If user data packets need to be encrypted and transmitted between VTEPs via a VXLAN tunnel, in addition to configuring the tunnel source IP address and destination IP address on the VTEPs at both ends of the VXLAN tunnel to be established for tunnel establishment, you also need to configure The encryption mechanism used for encrypted transmission requires a lot of configuration workload, especially when the number of VTEPs in VXLAN is very large, the workload of this static configuration method is even greater, which is not conducive to network deployment

Abstract

The invention provides a transmission method and device. The transmission method is applied to a first virtual extensible local area network tunnel end point VTEP in a virtual extensible local area network VXLAN. The method comprise the steps of determining a first encryption mechanism corresponding to a VXLAN tunnel between the first VTEP and a second VTEP according to a first encryption capability set of the first VTEP and a second encryption capability set of the second VTEP in the VXLAN; encrypting a first user data message to be sent to the second VTEP through adoption of the first encryption mechanism, thereby obtaining a first encryption message, and transmitting the first encryption message to the second VTEP through the established VXLAN tunnel; and receiving a second encryption message transmitted by the second VTEP through the established VXLAN tunnel, and decrypting the second encryption message through adoption of the first encryption mechanism, thereby obtaining a second user data message. Through application of the embodiment of the method and the device, the VXLAN deployment can be optimized.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a transmission method and device. Background technique [0002] Virtual Extensible Local Area Network (Virtual Extensible Local Area Network, VXLAN) technology is based on Internet Protocol (Internet Protocol, IP) network, using "Media Access Control (Media Access Control) in User Datagram Protocol (User Datagram Protocol, UDP)" ( Layer 2 Virtual Private Network (Virtual Private Network, VPN) technology in the form of "MACin UDP") encapsulation. [0003] VXLAN includes multiple VXLAN tunnel endpoints (VXLAN Tunnel End Point, VTEP). VXLAN tunnels can be established between VTEPs to exchange user data packets between them. If user data packets need to be encrypted and transmitted between VTEPs via a VXLAN tunnel, in addition to configuring the tunnel source IP address and destination IP address on the VTEPs at both ends of the VXLAN tunnel to be established ...
