Block chain network transmission method and transmission medium based on KAD gemini model

Abstract

The invention relates to a block chain network transmission method based on a KAD double-sub-model and a storage medium. A node ID XOR distance value set between any source node A and a known peer node is obtained through calculation, a node B corresponding to the maximum value in the set is selected, a double-sub-node B of the node A is obtained, and continuous refreshing is carried out. The larger the ID XOR distance between the nodes is, the larger the difference of the adjacent nodes in the K buckets of the two nodes is, and when the source node carries out data transmission, information is synchronized to the corresponding double sub-nodes and is synchronously propagated, so that the coverage rate of the data in the network is improved, and the propagation redundancy is reduced. Meanwhile, the neighbor nodes in the K buckets of the nodes are reordered, the neighbor nodes feed back own network bandwidths and transmission time to the source node in a mode of sending test packets, the arrangement sequence of the neighbor nodes is determined according to delay parameters, and the high-order neighbor nodes have the priority transmission right, so that the network transmission efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of block chain network transmission, in particular to a block chain network transmission method and transmission medium based on the KAD twin model. Background technique [0002] The traditional network structure is based on the client-server model. As the provider of resources and services, the server is responsible for processing the client's request, and the message transmission between the clients is also forwarded by the server. Participants in the P2P network architecture are both clients and servers. Participants can share resources with each other, avoiding the forwarding process of the server, so that the operation of the entire network does not require a centralized management organization. [0003] The Kademlia protocol is a structured P2P network protocol that realizes efficient resource discovery by building a distributed hash table as a node list and performing periodic maintenance.

Problems solved by technology

[0005] 1) During data transmission, there will be a large amount of information redundancy, resulting in delays in data transmission and waste of network resources

[0006] 2) Since the node selection in the K-bucket is updated based on the XOR logic distance of the node ID, the network bandwidth problem between nodes is not considered
