Abstract

The invention provides a splitter for preventing network outages. The splitter comprises a single-chip microcomputer and an application-specific integrated circuit (ASIC) chip. The ASIC chip includes a first port, a second port, a third port, and a management interface. The first port is connected with a first VSU device. The second port is connected to a second VSU device. The third port is connected with an aggregation device. The management interface is connected with a management interface of the single-chip microcomputer. The single-chip microcomputer is used for controlling the ASIC chip to receive a message from the aggregation device through the third port and transmit the message to the first VSU device through the first port; and controlling the ASIC chip to transmit the message to the second VSU device through the second port when the first port fails. The invention ensures no network outage between a VSU system and the aggregation device.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a splitter for preventing network interruption. Background technique [0002] Standard networking topology based on VSU (VirtualSwitchingUnit, virtual switching unit), such as figure 1 As shown, in order to ensure high availability, the reliability of the equipment deployed at the core layer (VSU equipment side) is extremely high. In order to meet this reliability, there are two VSU equipment in the VSU system as backup for each other. The S2150G or S2652G at the aggregation layer Theoretically, the -E device and the two VSU devices at the core layer must have a link connection, that is, the S2150G needs to be connected to the two VSU devices respectively, and the S2652G-E device needs to be connected to the two VSU devices respectively, so as to ensure that the VSU If any one of the devices is abnormal, the other VSU device can still be connected to the switch at the aggregati...
