Problems solved by technology

[0005] With the continuous development of the network scale, the requirements for the processing capacity of the router are getting higher and higher. In the prior art, when the performance of the router cannot meet the requirements, only the software and hardware of the router can be upgraded, and the cost is very high.

Embodiment Construction

[0067] The embodiments of the present invention will be further described below in conjunction with the drawings and examples.

[0068] Existing PCIe Switch chips generally have a function of configuring a certain port as an NT (NonTransparent, non-transparent bridge) port mode. The NT port can realize isolation between two PCIe systems, preventing system competition caused by simultaneous initialization of the same device in the system by different processors when multiple PCIe systems are powered on or reset. At the same time, data exchange between two PCIe systems can be realized through the conversion function of the NT port. Therefore, if a PCIe port with sufficient bandwidth is reserved on the PCIe Switch and the corresponding physical port is drawn out, two or more routers can be physically connected through the physical port by using a PCIe cable, and at the same time the routers can be connected to each other. The ports used are set to NT mode and corresponding confi...

Abstract

The present invention discloses a router stacking method, a system and an apparatus based on fast peripheral equipment interconnecting PCIe exchange architecture. The method comprises the following steps: initializing non-transparent bridge NT port under the PCIe switch of a first router, the PCIe switch of the first router connects with the PCIe switch of a second router by the NT port; and realizing message interaction between the first router and the second router. The router stacking method based on PCIe exchange architecture stacks two or more PCIe exchange architecture routers into a more high-end router system which has more ports and greatly-improved process ability, and is applied to higher-required networking environment.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method, system and device for stacking routers based on a PCIe switching architecture. Background technique [0002] PCIe (Peripheral Component Interconnect Express, fast external device interconnection) bus provides high-speed, high-performance, full-duplex point-to-point, multi-channel bundled differential link connection general I / O interconnection for computer and communication platform device interconnection Even the bus. Each device in the system has its own bus, and establishes point-to-point communication by directly connecting to the Switch (switch) device. The PCIExpress bus implements Traffic route (traffic path) and resource management with Switch devices, and at the same time, data transmission becomes discrete packets of data (Discrete packets of data), adding QoS (Quality of Service, quality of service) function, through priority data packet sched...
