AI Technical Summary

Problems solved by technology

The information sent by the motherboard processor to other processors on the smart interface board can only be forwarded through processor 1.
Once processor 1 is not working properly, the information exchange path between the processor on the motherboard and other processors on the intelligent interface board is also cut off

Abstract

The invention discloses a system of single-point to-a plurality of points communication, comprising an integrated circuit board which has a main processor and an integrated circuit board which has a plurality of slave processors; the integrated circuit board which is provided with a main processor and the integrated circuit board which is provided with a plurality of slave processors communicate through a serial port. The integrated circuit board which has a plurality of slave processors also comprises a connection unit which is connected with the serial port and used for realizing the intercommunication between the main processor and the slave processors through a token. The invention discloses a method of the single-point to-a plurality of point communication, and the main processor of the invention can communicate with a plurality of processor serial ports on an intelligent interface board through a serial port without adding other control signals.

Description

Technical field [0001] The invention involves the field of communication technology, especially a method and system of multi -point communication. Background technique [0002] The router and the Ethernet switch undertake the functions of the forwarding and transmission path selection of IP packets in the Internet.The main functions of traditional low -end routers and switches are gathering and business management, which are generally on the edge of the network.On the one hand, low -end routers and switches can meet the mid -to -low -end performance requirements of general network equipment, and on the other hand, they also have better price cost advantages.However, the traditional low -end router relies on a single processor for processing. Traditional low -end Ethernet switches rely on simple -dedicated chips with simple internal functions to achieve Ethernet business.In the face of rich business characteristics, such as IPSEC, IPS, voice and wireless, these simple devices are ...
