Abstract

The invention discloses a redundancy switching system for PCIE bus-based multi-mainboard interconnection. The system comprises a first mainboard, a second mainboard, a third mainboard, a fourth mainboard, a first switching circuit and a second switching circuit; the first mainboard, the second mainboard, the third mainboard and the fourth mainboard are connected with the first switching circuit and the second switching circuit; a first switching board comprises a first interface, a second interface, a third interface, a fourth interface and a first packet switcher; the first mainboard, the second mainboard, the third mainboard and the fourth mainboard are installed with virtual machines; and the first mainboard, the second mainboard, the third mainboard and the fourth mainboard are mutually redundant, so that the first switching board and a second switching board form a redundancy structure. According to the redundancy switching system for the PCIE bus-based multi-mainboard interconnection, the multi-time switching of a data signal is avoided; the network delay is shortened; the network bandwidth is increased; and high availability of a network is ensured.

Description

technical field [0001] The invention belongs to the technical field of network communication, in particular to a redundant switching system based on PCIE bus multi-master interconnection. Background technique [0002] With the explosive development of Internet information technology, the amount of data in the network has increased in a blowout manner. The gigabit network bandwidth of a single server can no longer meet the current information processing needs. Fiber cards and InfiniBand cards have become the mainstream network cards for current servers. [0003] Due to the need to achieve intercommunication between multiple hosts, the high-speed network card of each host needs to be mounted on the PCIE bus of the system internally, and connected to a high-bandwidth switch externally, such as a fiber optic switch or an Infiniband switch. This forms a simple star switching network. It can be seen that the communication between hosts is based on the network card and Ethernet. T...
