Abstract

The invention comprises: a switching unit and at least two switch control units. Said switching unit comprises a switching module with at least two uplink ports respectively connected to the root multiplexer of the control units. Said switch control units are used to control said switching module to turn on or turn off.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for realizing switchover of active and standby controllers. Background technique [0002] PCI (Peripheral Component Interconnect, external device interconnection) Express (extension) bus is a serial bus for point-to-point transmission, and each pair of transmission lines has an exclusive bandwidth. There is an RC (Root Complex, root multiplexer) in the PCI Express bus system, which is used to connect the CPU (Central Processing Unit, central processing unit) and Memory (memory) and the PCI Express bus. One RC can support one or more PCI Express Each port defines an independent hierarchical domain, and each hierarchical domain may consist of a single endpoint device, or a sub-hierarchical domain including switching devices and multiple endpoint devices. The RC generates transaction requests on behalf of the CPU, initiates configuration reques...
