A protection device for communication equipment

Abstract

The invention discloses a protection device for communication equipment. The working board includes an optical splitter, a first optical switch, a second optical switch and a first service module, and the protection board includes a second service module. When the equipment is running normally, the working boards process services normally; the protection boards perform backup. The first optical switch (1x2 optical switch) receives the sending data from the second service module when the first service module fails, and transmits the sending data to the optical splitter; the optical splitter transmits the sending data through the working port and the protection port The data is transmitted to the working port and the protection port of the peer device; the second optical switch (2x2 optical switch) receives the receiving data transmitted by the peer device through the working port and the protection port; when the first business module fails, it will receive the data transmission For the second service module of the protection board. In this way, the protection process from the working board to the standby board is realized, and a single service node failure is avoided on the basis of traditional APS port protection.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a protection device for communication equipment. Background technique [0002] Taking protection measures for important functions or important components of communication equipment is one of the important means to improve the reliability of communication equipment. With the continuous improvement of the integration of communication equipment and the requirements for energy saving and consumption reduction, when designing and implementing communication equipment, business processing functions and external interfaces are usually concentrated on one physical board for implementation. Based on this, the traditional method of using APS (Auto Protection Switch, automatic protection switching) for line protection or 1+1 for device-level single-board protection will be subject to the following limitations: APS can only implement line interface protection, and service processing bec...

Based on this, the traditional method of using APS (Auto Protection Switch, automatic protection switching) for line protection or 1+1 for device-level single-board protection will be subject to the following limitations: APS can only implement line interface protection, and service processing becomes Single point of failure; while 1+1 board-level protection can protect ports and services at the same time, due to the switching between the link layer and the service processing layer, the switching time is long and the service interruption is obvious
