Communications method and communications system

摘要

A real-time communications system for decentralized management is accomplished which was not implemented conventionally. To achieve this, the following techniques are employed: (1) Path control based on the priority; and (2) Priority change at each node. When carrying out real-time communication between a plurality of information processors, each communication node (information processor) can change the priority, and establish different paths for each of the priority. Using these techniques makes it possible to implement real-time communication with a very short quantum time; to obviate the need for retransmission; to implement simultaneous communications through different paths between the same communication nodes; to achieve later expansion with regard to the communication latency and bandwidth; to connect far more communication nodes than the centralized management type; and to carry out robust communications even if part of communication paths is damaged.
