Communication method between router nodes and switching method thereof

Abstract

The invention discloses a communication method between router nodes, comprising: customizing the selection of the first transaction data in the standard OSPF work flow, so that it becomes the second transaction data matched with the block chain communication; The standard OSPF workflow performs secondary configuration of each node, so that the second transaction data between the nodes cooperates with each other and realizes synchronization; based on the blockchain communication workflow, the corresponding block is generated for the second transaction data, and each node After verification, it is added to the blockchain. The invention provides a communication method between router nodes, which innovates and improves the timing of sending or receiving transaction data and integrates standard OSPF and blockchain processes, which only modifies the standard blockchain process without modifying the OSPF standard process , to ensure compatibility with existing protocols and interoperability with existing networks.

Description

technical field [0001] The present invention relates to a communication method used in the case of network communication equipment communication. More specifically, the present invention relates to a communication method and a handover method used in the case of router node communication. Background technique [0002] Routing protocol data needs to be frequently exchanged between routing nodes in a communication network. Many routing protocols in the communication network (for example: Open Shortest Path First Protocol, OSPF) generally adopt the designated router mechanism, that is, all routing nodes only exchange protocol packets with designated router nodes, avoiding interaction between two routing nodes. [0003] The widely used designated router mechanism uses designated router nodes (and / or backup designated router nodes) as the center of communication between routing nodes, which belongs to a centralized communication system, and has the following problems: [0004] ...

AI Technical Summary

Problems solved by technology

[0004] a) It is easy to cause a single point of failure: the paralysis of the central node (for example: OSPF designated router node and / or backup designated router node) can easily lead to the collapse of the entire network, although the backup designated router can solve the problem of designated router paralysis in the short term, however Backup designated router technology is still a centralized structure, which cannot eliminate single points of failure like a distributed structure;

[0005] b) Not applicable to high dynamic network: the election process of the central node needs to converge. Network business communication is frequently interrupted;

[0006] c) Vulnerable to attacks: When the central node encounters a network attack, there will be communication failures and errors in the entire network, reducing network reliability and security
