Switching network communication system, implementing method and switching unit

Abstract

The invention provides a switching network communication system which includes a main control board, a line card board and a switching device. The switching device includes a PCIE switching unit, the line card board processes date plane communication through the PCIE switching unit. The invention also provides a switching network communication implementation method which includes steps: the main control board processes spatial allocation to the PCIE switching unit and the line card board; the line card board processes date plane communication through the PCIE switching unit. The invention also provides a switching device. An embodiment of the invention uses the switching network based on PCIE bus as a date bearing plane, uses the switching network based on internet as a control plane, and provides an network equipment with low cost, high performance and high reliability.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a switching network communication system, an implementation method and a switching device. Background technique [0002] With the development of the Internet and the gradual increase in traffic, the performance requirements for network equipment such as routers, switches, and gateways are getting higher and higher, and the services that need to be processed are becoming more and more complex. Therefore, the current medium and high-end network equipment switching networks generally use data The separation of the bearer plane and the control channel enables communication devices to adopt distributed forwarding. Such as figure 1 A step-by-step network device is shown, including main control board, line card board and switch board. The control unit of the main control board is usually a CPU (Central Processor Unit, central processing unit), and the control unit of the line c...

AI Technical Summary

Problems solved by technology

Network equipment based on Ethernet switching chips, because Ethernet switching chips are widely used in switches, the price is low, but Ethernet will inevitably be congested in the case of large traffic, and it cannot support QoS (Quality of Service) , quality of service), flow control, etc.; although existing technologies also attempt to optimize the switching network based on Ethernet chips through various central scheduling, line card board queue management, etc., the complexity and cost are very high

Therefore, the communication equipment of the existing switching network is either costly and complex to implement, or cannot meet complex business requirements
