Service transmission method, device, equipment and medium

Abstract

The invention discloses a service transmission method, device, equipment and medium. The method includes: establishing an MPLS label distribution protocol LDP tunnel from a first access router AR to a second AR in an Internet Protocol IP bearer network according to Border Gateway Protocol Multi-Protocol Label Switching BGP MPLS; Backbone CSC VPN; enable the MPLS function of the route reflector RR and the uplink interface of the user edge device CE, and establish the external border gateway protocol EBGP neighbor relationship between the RR and the second AR and the CE and the first AR, so that multiple A VPN service is embedded in the backbone CSC VPN of the IP bearer network through the second AR for transmission. According to the embodiment of the present invention, multiple services can be merged into a single service to be uniformly carried by the IP bearer network, thereby reducing maintenance difficulty.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a service transmission method, device, equipment and medium. Background technique [0002] The current digital mobile network (mobile digital communication network, MDCN), network management system (Network Management System, NMS), business operation support system (Business & Operation Support System, BOSS), office network (Office Automation, OA), etc. , IP) bearer network with multi-network and multi-service coexistence, many networks, repeated links, large number of network elements, and difficult maintenance, etc. O&M problems are becoming more and more prominent. [0003] In existing technical solutions, such as figure 1 As shown, all kinds of services are connected to the access router (Access Router, AR) device through the nearest customer edge device (CustomerEdge, CE), and the backbone network AR device of the IP bearer network establishes and runs mul...

AI Technical Summary

Problems solved by technology

[0003] In existing technical solutions, such as figure 1 As shown, all kinds of services are connected to the access router (Access Router, AR) device through the nearest customer edge device (CustomerEdge, CE), and the backbone network AR device of the IP bearer network establishes and runs multiple virtual private networks (Virtual Private Network, VPN ), and at the same time, the service access on the CE side requires the AR side to cooperate with the use of policies and routing (which will lead to excessive port occupation of the AR device and high requirements on device capabilities), and the development of services requires the intervention of the backbone network (AR device), and the VPN service of the backbone network Complex, difficult to manage and many other issues

Service provisioning, service adjustment, and routing adjustment all require the approval and participation of the group's IP bearer network maintenance personnel, and the efficiency of service provisioning is low
