Abstract

The invention discloses an intelligent distribution device and method of video bandwidth. The intelligent distribution device comprises at least one service module, a control module, a PCIe exchange module and a bandwidth distribution module, wherein the bandwidth distribution module is provided with a configuration entry; the PCIe exchange module is provided with a PCIe link switching unit. Simultaneously, the intelligent assembling method of the video bandwidth has the advantages that when congestion occurs, the PCIe exchange module reports congestion information and state information, the control module issues the state information and video data input information to the bandwidth distribution module, the bandwidth distribution module matches the state information and the video data input information to an optimally-matched configuration entry and generates configuration information; the PCIe exchange module adjusts the PCIe link switching unit according to the configuration information and finishes intelligent bandwidth distribution of all ports of the PCIe exchange module. The intelligent distribution device and method disclosed by the invention have the advantages that the intelligent bandwidth distribution of the ports is realized and the bandwidth resources are fully utilized.
