Extensible dual-channel cooperative network communication system and device

Abstract

The invention relates to an extensible dual-channel cooperative network communication system and device. The system comprises a plurality of nodes, wherein network communication occurs in private channels and shared channels among the nodes; each node is provided with a plurality of private channel communication ports and a shared channel communication port; the private channel communication ports are used for being connected with private channel communication ports of other nodes and establishing private channel communication connection with the directly connected nodes; and the shared channel communication port is used for being connected with the shared channel communication ports of other nodes and establishing shared channel communication connection with the nodes which are directly connected and indirectly connected. The implementation mode of the shared channel is as follows: an unvarnished transmission forwarding module is arranged between the shared channel communication ports in the nodes, data received by one port can be automatically forwarded to all other activated shared channel communication ports, and a virtual shared channel is realized. By separating a private channel and the shared channel, communication between specific nodes can be synchronously carried out to avoid occupying shared channel resources; the virtual shared channel is realized by using serial unvarnished transmission forwarding, so that the shared channel can be automatically expanded along with the increase of nodes; and the communication for determining a spatial position relationship between the private channels can also make up the defect that the information is inconvenient to integrate into the shared channel.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an expandable dual-channel cooperative network communication system and device. Background technique [0002] The channel through which a network system sends information is called a channel. There are various forms of channels, but they can be divided into shared channels and private channels from the perspective of accessibility. [0003] A shared channel is a channel that can be shared by multiple nodes; a private channel is a channel that is limited to two nodes and cannot be accessed by other nodes. [0004] Generally speaking, shared channels can realize centralized management and multiplexing of resources, and use the same frequency domain, time domain, and space resources with higher efficiency; if private channels can realize shielding from the outside world, they can monopolize all time domain / frequency Domain resources, the bandwidth allocated to each node is hig...

Problems solved by technology

[0007] However, there are difficulties in how to balance the efficient shared channel and the scalability of the wired network: if the shared channel is laid in advance, it needs to be configured for access when adding a new edge node; The attenuation that comes limits system performance
