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 e

Abstract

The invention discloses a communication method between router nodes, which comprises the following steps of: carrying out user-defined selection on first transaction data in a standard OSPF working process to enable the first transaction data to become second transaction data matched with blockchain communication; Performing secondary configuration on the nodes based on the standard OSPF workflowto enable the second transaction data between the nodes to be matched with each other so as to realize synchronization; And generating a corresponding block for the second transaction data based on the block chain communication workflow, and adding the block into the block chain after each node verifies the block. The invention provides a communication method between router nodes, which innovatively improves and fuses standard OSPF (Open Service Provider Function) and block chain processes aiming at the opportunity of transmitting or receiving transaction data, only modifies the standard blockchain processes, does not need to modify the OSPF standard processes, ensures compatibility with the existing protocol, and can be interconnected and intercommunicated with the existing network.

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] ...
