Problems solved by technology

Most of the implementation schemes use level conversion chips, such as DS90CR217 / 218, etc., to convert parallel data into LVDS (low-level differential signal) parallel differential signals for transmission. During the transmission process, more differential lines are required, typically 8 pairs For transmission; because there are many signal lines for transmission, such as typical 22-26 cores, plugs, sockets, cables, etc. are relatively expensive
Moreover, the transmission distance of the dedicated stacked board is relatively short, mostly 0.5m-1m

Embodiment Construction

[0018] The realization of Ethernet switch stacking is usually achieved by interconnecting the Gigabit interfaces between the Ethernet switches, that is, the Gigabit parallel signals on the switching chips between the stacked Ethernet switches can be transmitted to each other through the transmission line, and the Ethernet is realized. A stack of switches.

[0019] A method for realizing Ethernet switch stacking provided by the present invention is to convert the Gigabit parallel 10-bit interface signal output by the Ethernet switch into a Gigabit serial 1.25G transceiver differential signal through a conversion circuit, and convert the Gigabit serial The line signal is transmitted to another Ethernet switch that needs to be stacked with this Ethernet switch through cables; similarly, for receiving the Gigabit serial signal sent by another Ethernet switch that is stacked with this Ethernet switch, the It is converted into a gigabit parallel signal through a conversion circuit a...

Abstract

The method for implementing Ethernet exhcnage stacking includes the following steps: converting the giga-parallel signal outputted by Ethernet exchanger into giga-serial signal by means of conversioncircuit, transferring said giga-serial signal into another Ethernet exchange to be stakced with the above-mentioned Ethernet exchanger by means of cable, and when the Ethernet exchange is used for receiving giga-serial signal transferred from another Ethernet exchanger, converting the giga-serial signal into giga-parallel signal by means of conversion circuit, and connecting it into said Ethernetexchanger.

Description

technical field [0001] The invention relates to a method for realizing network switch stacking. Background technique [0002] Ethernet switch stacking is to connect multiple Ethernet switches together to form an Ethernet switch that can provide more ports and provide access services for more users to meet the needs of networking. Stacked Ethernet switches can also achieve unified network management, that is, the management of multiple stacked Ethernet switches is as convenient as the management of a single Ethernet switch. Due to its flexible scalability and unified external network management, the Ethernet switch supporting the stacking function has been paid more and more attention in the enterprise network and broadband networking applications. The implementation of stacking technology is usually realized by using stacking interface modules and stacking cables, that is, after the Gigabit bus in the switch is processed by the corresponding processing circuit, it is connec...
