Method for Ethernet board-level protection, device and system

Abstract

The invention relates to the technical field of communication, in particular to a method for Ethernet board-level protection, a device and a system. In the method, when a main switching aggregation board is in a normal working state, a corresponding input and output physical link between the main switching aggregation board and processing equipment is in an activated state, and a corresponding input and output physical link between each standby switching aggregation board and the processing equipment is in a closed state; and when the main switching aggregation board is in an abnormal working state, an input and output physical link corresponding to the main switching aggregation board is closed, an input and output physical link corresponding to a standby switching aggregation board is activated, and the standby switching aggregation board is switched into the main switching aggregation board for use. In the method for Ethernet board-level protection, the device and the system, provided by the embodiment of the invention, by arranging one main switching aggregation board and a plurality of standby switching aggregation boards, the main switching aggregation board is switched to the standby switching aggregation board when the main switching aggregation board cannot normally work, so that the stability of service processing and the safety for service data processing are guaranteed.

Description

technical field [0001] The present invention relates to the technology in the communication field, in particular to a method, device and system for Ethernet board-level protection. Background technique [0002] With the development of network technology, Ethernet technology has increasingly become an important technical means for social production, office and life informatization. Usually, the part of the network that directly faces user connections or access to the network is called the access layer, and the part between the access layer and the core layer is called the distribution layer or aggregation layer. [0003] The access layer mainly solves the problem of terminal user access. The access layer allows terminal users to connect to the network; The uplink physical link of the core layer; the core layer is the aggregation point of multiple convergence layer devices, and has the functions of routing and forwarding and processing a large amount of information.

AI Technical Summary

Problems solved by technology

These two protection methods have some disadvantages. The LAG protocol is relatively complicated, and the switching time is seconds. In some sudden failures, the data protection is not complete; the TPS protection cannot realize port protection and link protection. The application environment also limited

[0007] To sum up, in the prior art, the service processing reliability caused by the failure of the aggregation board is poor, and the data security is poor caused by the defect of the access protection method.
