Problems solved by technology

There are two defects in this solution: the bandwidth of network communication is limited by the network card, and when the load balancer is deployed as the main road, it will often become a network bottleneck; there is a single node failure, and redundant equipment needs to be purchased during deployment, which increases the cost
There are two defects in this solution: the data communication between the two circuit boards undergoes multiple signal conversions, which increases power consumption and delay; the device has a single node failure, and redundant devices need to be purchased during deployment, which increases the cost

Abstract

The present invention discloses a load balance redundancy switching system of a control panel directly connected with a switch board bus. The system comprises: a first interface being a PCIe externalinterface of a first switch board; a second interface being a PCIe internal interface of a first switch board; a third interface being a PCIe external interface of a second switch board; a fourth interface being a PCIe internal interface of a second switch board; a first control module and a second control module which are respectively configured to perform output of the input PCIe data after loadbalance, wherein the first control module and the second control module are redundant to each other to allow the first switch board and the second switch board to form a redundant structure; and a first grouping switch and a second grouping switch which are respectively configured switch the PCIe data and Ethernet data to communicate with an external Ethernet. The load balance redundancy switching system of the control panel directly connected with the switch board bus avoid multi-time conversion of data signals, reduce the network delay and increase the network bandwidth.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dual-channel fusion emergency video encrypted wireless transmission device. Background technique [0002] With the vigorous development of Internet technologies such as clustering and cloud computing, application delivery load balancers have become a common four-layer / seven-layer network load balancing device in data center applications. There are two common implementations of this load balancing device: [0003] The first is to integrate a dedicated network card or a high-speed Ethernet card on the control board circuit board, and achieve the purpose of data flow load balancing through specific software and drivers. There are two defects in this solution: the bandwidth of network communication is limited by the network card, and when the load balancer is deployed as the main road, it will often become a network bottleneck; there is a single node failure, and re...
