Problems solved by technology

Due to the large number of switches controlled by the control center and scattered in various places, it may not be possible to detect the location of the faulty device in time and make correct processing immediately, resulting in inconsistent protection switching time, so it cannot meet some special communication requirements, such as in 5G systems. Requirements for 1 millisecond (1ms) protection switching in ultra-reliable low latency communication (URLLC)

Abstract

The telecommunication level network switch is equipment with a 2U / 1.5 U height machine frame and is composed of two sub-network switches. According to the networking requirement of a client, the two sub-networks can be set to be two independent network switches for switching, and the two independent network switches respectively execute the network switching function; or the two sub-network switches are set as telecommunication level network switches which are mutually protected and switched, when one of the sub-network switches fails, the control processor monitors, detects and processes a hardware line, and the low-speed interface unit of the sub-network switch can be quickly switched to the other sub-network switch, so that the fault of the sub-network switch is avoided. And the traffic transmission work is not interrupted. Therefore, all the units and the modules are switched through the high-speed backboard, and maintenance or updating work of the units or the modules can be provided under the condition that work of the switch is not interrupted.

Description

technical field [0001] This disclosure document is about a carrier-grade network switch, in particular a network switch with a 2U / 1.5U height frame and a hot-swap protection switching function. Each low-speed interface unit in a 2U chassis supports 16 optical interfaces; each low-speed interface unit in a 1.5U chassis supports 8 optical interfaces. Background technique [0002] Most of the network switches currently used by Data Service Providers are industrial-grade hardware circuit designs. Except that the power supply and fan parts have hot-swappable protection switching, its most important high-speed interface interface / high-speed network exchange processing / control processing unit and low-speed interface interface unit do not have hot-swap protection switching function. In order to meet the requirements of high transmission reliability, two sets of network switches are generally used to connect to each other, and the transmission protection switching is performed throu...
