Problems solved by technology

[0007] In the Hub-Spoke networking mode, the network scale is large and the network environment is in the process of dynamic changes. At this time, configuring each VXLAN tunnel in the network through the static configuration method requires manual configuration of each VXLAN tunnel one by one. There are many processes and complicated operations.

Abstract

The embodiment of the invention provides a tunnel establishment method and a communication system, and relates to the technical field of the communication. A VXLAN tunnel is established by using the SDN controller to ideologically learn a neighbor address of a VTEP. The method comprises the following steps: starting a VTEP Server through a SDN controller to monitor the access of a VXLAN Client; configuring the neighbor address of the VETP Client as the local IP address of the VTEP Server; actively learning the VTEP neighbor address information if the SDN controller senses the access of the VXLAN Client; if the active learning cannot be realized, passively learning the VTEP neighbor address information through a packet in message; and then issuing a command for establishing the neighbor address as the VTEP of the local IP address of the VTEP Client to the VXLAN Server by the SDN controller. The technical scheme provided by the embodiment of the invention is suitable for the establishment process of the VXLAN tunnel.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of communication, in particular to a tunnel establishment method and a communication system. [0003] 【Background technique】 [0004] Virtual Extensible LAN technology (VXLAN) is a tunnel encapsulation technology that can establish a Layer 2 network tunnel on the basis of a Layer 3 network, thereby realizing cross-regional Layer 2 interconnection and realizing a large Layer 2. Currently, in some actual application scenarios, using VXLAN to implement large Layer 2 requires the Hub-Spoke networking mode. In this networking mode, there is a central node (Hub site) and multiple access nodes (Spoke sites), and the data exchange between Spoke-VTEP (VTEP-Client, VXLAN tunnel terminal node client) must pass through Hub -VTEP (VTEP-Server, VXLAN tunnel terminal node server), instead of allowing direct data exchange between Spoke-VTEPs. In many cases, the network scale in the Hub-Spoke networking mode is rel...
