Abstract

The invention discloses an establishment method and system for a virtual extensible local area network tunnel and an authentication server and relates to the technical field of communication. According to the method, the system and the related device, in a dial-up Internet access process of a user side device, VxLAN (Virtual Extensible LAN) tunnel configuration information such as address information of a network side tunnel device and a virtual extensible local area network identity is sent to the user side device, so the user side device can establish the VxLAN tunnel according to the configuration information. The realization method is simple and the efficiency is high. The method provided by the invention is applicable to automatic configuration of the VxLAN tunnel under the conditionthat the user side device is a home or enterprise gateway. Devices in a home network or an enterprise network can share the VxLAN tunnel. Moreover, the gateway has destination address identification capability, so guide configuration of traffic can be realized through utilization of a control instruction. The tunnel can be established without a VxLAN network card and the user side device is changed a little, so the establishment complexity of the VxLAN tunnel is further reduced, and the efficiency is improved.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a method, system and authentication server for establishing a virtual extensible local area network tunnel. Background technique

[0002] VxLAN (Virtual Extensible LAN, Virtual Extensible Local Area Network) technology is an international technical standard formulated by the IETF (The Internet Engineering Task Force, Internet Engineering Task Force) standard organization. Protocol) tunnel encapsulates the user's Layer 2 message and transmits it in the Layer 3 IP network. Using this technology, a user-defined Layer 2 network can be built across the Layer 3 IP network. Private addresses, even non-IP packets. Since VxLAN technology is a stateless tunnel technology, the key issue in establishing a tunnel is how to configure the tunnel IP address and VNI (VxLAN Network Identifier, VxLAN Network Identifier) ​​on the network side at the tunnel entry point.
