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

Embodiment Construction

[0043] The present invention provides a single-point-to-multipoint communication system, comprising a board with a main processor and a board with multiple slave processors, the board with a main processor and a board with multiple slave processors The board communicates through a serial port, wherein the board with multiple slave processors also includes a connection unit connected to the serial port, which is used to implement the communication between the master processor and the slave processors through a token intercommunication.

[0044] The main processor specifically includes: a token acquisition unit, used to obtain a token when the system is initialized; or obtain a token from a message returned from the slave processor; a message sending unit, used to send the message carrying the token The message is sent to the target slave processor, and the message can also include the sending data of the main processor; the message receiving unit is used to receive the message ...

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 relates to the technical field of communication, in particular to a method and system for point-to-multipoint communication. Background technique [0002] Routers and Ethernet switches undertake functions such as forwarding of IP data packets and selection of transmission paths in the Internet. The main functions of traditional low-end routers and switches are collection and service management, and they are generally located at the edge of the network. On the one hand, low-end routers and switches can meet the low-end performance requirements of general network equipment, and on the other hand, they also have a good price and cost advantage. However, the traditional middle and low-end routers rely on a single processor for processing, and the traditional middle and low-end Ethernet switches rely on dedicated chips with simple internal functions to realize the processing of Ethernet services. In the face of the requirements of rich busin...
