Method and system for realizing dual attachment or multiple attachment of user network boundary device

Abstract

The invention relates to a method for realizing dual-attach or multi-attach in user network edge device and a relative system, wherein said method comprises: the target user network edge device distribution network address is accessed into IPLS solid, to supply service to the target user network edge device; the operator network edge device checks present path, if the path between the source user network edge device and the target user network edge device has accidence, the backup operator network edge device obtains the recognize information of target user network edge device, and switch the target user network edge device to the backup operator network edge device. The invention uses operator network edge device to check path accidence, and trigger the switch of transfer path of user network edge device, to realize the dual-attach or multi-attach of user network edge device.

Description

technical field [0001] The invention relates to a virtual private network technology, in particular to a method and system for realizing dual-homing or multi-homing of user network edge equipment. Background technique [0002] As users have higher and higher requirements for network security, reliability and network processing capabilities, operators must introduce sufficient capacity and various diversity means into the network at the beginning of network design in order to provide users with high enough services Ability to reduce the impact of failures as much as possible, improve network priority recovery capabilities, dual intervention capabilities, and multiple routing capabilities, etc., to ensure the normal provision of services and make users highly satisfied with the services provided. Therefore, under the comprehensive consideration of several factors such as equipment integration, cost, disaster recovery capability and network security, the concept of dual homing ...

AI Technical Summary

Problems solved by technology

[0008] (1) Tunnel faults between PEs cannot be notified from PEs to CEs, so CEs need to detect faults through their own running routing mechanism, and CEs have poorer processing capabilities than PEs, so the efficiency is very low and the path The switching speed is slow, and it cannot be combined with the existing routing fault detection technology on PE;

[0009] (2) CE must be able to run routing protocols to use this method to achieve dual-homing of CE, so static routing devices cannot be supported, and the requirements for CE are high
