Method and system for power failure protection

Abstract

The embodiment of the invention discloses a power-fail protection method and system. The power-fail protection method and system are applied to a looped network comprising a first device, a second device and a third device, the looped network bears a first service, and the second device comprises a first service port and a second service port. The method comprises the steps that a power-fail protection device is set up and used for assisting the first device in transmitting the first service to the third device; the first device sets up a first LSP, the first LSP is used for bearing the first service, and the IP address of a next-hop device of the first LSP is arranged as the IP address of the third device; the first device sends the first service to the power-fail protection device through the first LSP; if the second device is powered off, the power-fail protection device enables a first protection port and a third protection port to be communicated through a photoswitch, and the direct connection of the first device and the third device is achieved. The power-fail protection method and system are applicable to the transmission service by means of an MPLS protocol.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a power-down protection method and system. Background technique [0002] Group customers are one of the key development directions for operators to develop their business. At present, most of the group customers' equipment is placed on the customer side, using AC power supply, and there is no backup power condition. For reasons such as saving energy, group customers often cut off power to equipment during non-working hours. Therefore, in the current networking, in order to ensure that the services of other user equipment in the ring network are not affected, the equipment on the client side is not placed in the net. Because the equipment on the client side cannot be connected to the ring network, the service reliability of group customers is low. [0003] In order to ensure the reliability of the business of the group customers, the equipment on the customer sid...

AI Technical Summary

Problems solved by technology

[0005] Provide a method and system for power failure protection, which can solve the problem of high maintenance complexity due to the need to manually adjust the configuration of devices adjacent to the group device when a group device that uses the MPLS protocol to transmit services is powered off
