Method, system and device router overlapping based on PCIe exchange architecture

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

Method, system and device for stacking routers based on PCIe switching architecture technical field 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 The PCIe (Peripheral Component Interconnect Express, fast external device interconnection) bus provides a high-speed, high-performance, full-duplex point-to-point, multi-channel, universal I / O interconnection bus that can be bundled with differential links for the interconnection of computers and communication platform devices. Each device in the system has its own bus, and establishes point-to-point communication by directly connecting to the Switch (switch) device. The PCI Express bus implements Trafficroute (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 ...

Problems solved by technology

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.
