Description

Autonomous controllable router equipment based on orthogonal architecture

Technical Field

Background

There is no break in the research of high performance routers, and many companies and organizations have conducted corresponding researches, and there are many different directions from the overall architecture to specific hardware processors and software protocols, and the processors for network data processing are also in wonderful forms, such as multi-core processors, hardware parallel processors, programmable hardware processors, etc. However, the core software and hardware of the domestic network equipment such as the network processor and the operating system adopt foreign products, and information safety hidden danger exists, so that the autonomy of the routing equipment based on the domestic processor, the operating system and the like is urgently needed, and basic guarantee is provided for the national network and the information safety.

The traditional standard frame mode and the middle-set backboard orthogonal frame mode are mainly adopted in the existing equipment frame mode, the traditional standard frame mode is more applied to medium-low end route switching equipment, the backboard speed is generally up to 10Gbps, the upgrading space is limited, the backboard board needs a high-speed board, and the cost performance is not advantageous. And the rear-mounted backboard orthogonal frame mode is mainly applied to a 10Gbps platform and can be partially upgraded to a 25G platform. The disadvantage is that the high-speed signal needs to pass through the two-stage connector and the one-stage backboard through hole, which causes a certain signal attenuation, and the number of connector wires is increased, the power consumption of the chip is increased, and the heat dissipation and the bandwidth expansibility are difficult along with the further improvement of the backboard speed and the higher bandwidth requirement.
