Double-routing networking topology and application method thereof

Abstract

The embodiment of the invention provides a dual-routing networking topology and an application method thereof. The topology comprises a client, a client router, a first GPON line, a second GPON line,a first convergence router and a second convergence router, a LAN port of the client router is connected with the client, a first WAN port of the client router is connected with the first convergencerouter through the first GPON line, a second WAN port of the client router is connected with the second convergence router through the second GPON line, the first convergence router and the second convergence router are connected with the Internet, and the client router, the first convergence router and the second convergence router are respectively configured with BFD sessions, so that fault switching is realized through the BFD sessions. According to the system and the method provided by the embodiment of the invention, whole-course physical double routing is realized, single-point hidden dangers do not exist, meanwhile, the configuration operation of fault switching is effectively simplified, and quick construction of double-routing networking is facilitated.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communication networks, and in particular to a dual-routing networking topology and an application method thereof. Background technique [0002] The Internet dedicated line access service can provide customers with dedicated links of various rates, so that customers can directly connect to the IP backbone network through dedicated links, and realize convenient and fast high-speed Internet access services. [0003] At present, the main access methods of Internet leased lines include Packet Transport Network (PTN), Synchronous Digital Hierarchy (SDH) and Gigabit-Capable Passive Optical Network (GPON). . In the prior art, a dual-route link backup solution for an Internet leased line mainly adopts a PTN / SDH dual-router access solution. figure 1 It is a schematic diagram of the topology structure of the PTN / SDH dual-routing access solution in the prior art, such as figure 1 As shown, t...
