A method and network device for realizing inter-board communication

Abstract

The invention provides a method and network equipment realizing interboard communication. After an objective chip receives a message which is sent from a remote central processing unit (CPU) and packaged with an RCPU Header, different reading and writing operations can be implemented on the objective chip, and the message can be forwarded by removing the RCPU Header; and correspondingly, after a local chip receives a protocol message, the protocol message can be packed with the RCPU Header and then sent to the remote CPU for processing. The packaged RCPU Header between the remote CPU and the chip enables that interboard communication of a control message or the protocol message can be forwarded needless of employing a traditional CPU software forwarding method, thereby breaking through limitation due to traditional hardware design, greatly accelerating processing of protocol and control messages, and reducing the cost.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and network equipment for realizing inter-board communication by utilizing the characteristics of a remote CPU. Background technique [0002] With the development of data center technology, the core switching equipment of the data center will continue to pursue higher performance, greater bandwidth, and more features, so the latest and highest-end ASIC chips need to be used. This makes it possible for the same device to be interconnected by many chips from different manufacturers and different generations, which will greatly increase the complexity of the system. [0003] In traditional hardware design, the main control board is usually only responsible for the calculation of various network protocols, and does not participate in the forwarding of business packets. It generally requires high CPU performance and relatively large memory. In order not to affect the overall...

AI Technical Summary

Problems solved by technology

These protocol packets cannot be forwarded directly from the corresponding ports. Generally, they can only be sent to the CPU of the interface service board first, and then the CPU of the interface board performs software forwarding, which will seriously affect the system performance;

[0007] (3) Protocol packets received from the user port of the interface service board may need to be sent to the CPU of the main control board for processing

In this case, generally, the CPU of the interface service board can only be uploaded first, and then the CPU software of the interface service board is forwarded to the CPU of the main control board. Similarly, this will seriously affect the system performance
