A communication control method for network nodes

Abstract

The invention proposes a communication control method for network nodes, which relates to the field of network communication technology. The nodes in the network adopt a bus distributed structure on the real physical structure, and each of the nodes can communicate with each other; the nodes in the network Logically adopts a tree structure, the root node is at the highest level, and the first layer node is the next layer extension of the root node, and so on, each layer node is an extension of the parent node of the previous layer. The nodes of the present invention physically adopt a bus distributed structure, even if a node fails, it will not affect the operation of the entire network, ensuring the robustness of the system operation; logically, the relationship between each node is a tree structure, which is easy to traverse the entire The data structure of the system; the white list method simplifies the data storage structure in the node; the broadcast communication control according to the white list simplifies the complexity of synchronous control of all nodes in the tree structure; the node jump communication mode improves the success of node synchronous control Rate.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a communication control method for network nodes. Background technique [0002] Network topology (Network Topology) structure refers to the physical layout of various devices interconnected by transmission media. Refers to the specific physical (real) or logical (virtual) arrangement among the members of the network. If two networks have the same connection structure, we say that their network topology is the same, although their respective internal physical wiring and distance between nodes may be different. [0003] There are three types of communication between network nodes: one is unicast, at this time information is received and transmitted only between two nodes; the other is multicast, one node transmits messages to multiple nodes; the third is broadcast, A message sent by a node can be received by nodes in the entire network. [0004] The existing networ...

Problems solved by technology

Its disadvantages are: high cost, low reliability, and poor resource sharing ability

The disadvantage is that the cable used for the connection line is long and the cost is high; the network management software is complex; packet switching, path selection, and flow control are complex; this structure is not used in general LANs

[0009] The tree structure is a hierarchical centralized control network. The total length of its communication lines is short, the cost is low, the nodes are easy to expand, and it is convenient to find paths. However, except for leaf nodes and their connected lines, any node or its connected lines failure will affect the system
