METHOD FOR DECISION OF END-TO-END TRANSMIT PATH AND SEARCH OF TRANSMIT SLOT FOR TRANSMITTING END-TO-END LOW-LATENCY DATA AND NODE APPARATUS PERFORMING THE THEORY

摘要

The present invention relates to an end-to-end transmission path and a transmission slot discovery method for end-to-end low latency transmission. The method includes: (a) a path review request message including an address of a destination node when a first node in a network is a packet transmission start node; Transmitting to at least some of the nodes on the path on the plurality of candidate paths from the packet transmission start node to the destination node via flooding; (b) when the first node is a destination neighbor node neighboring the destination node among the nodes on the path, receives a path review request message from a previous neighbor node on a candidate path including the first node, and reviews the path. Transmitting a response message to the path review request message to the previous neighbor node which delivered the request message; (c) when the first node is an intermediate node other than the destination neighbor node among the nodes on the path, the first node receives a path review request message received from a previous neighbor node on a candidate path including the first node. Delivering to a next neighbor node on a candidate path including the updated neighbor message, and updating its response message to the previous neighbor node in response to the response message received from the next neighbor node; And (d) when the first node is a packet transmission start node that finally receives a response message, comparing the delays of the plurality of candidate paths included in the received response messages to determine end-to-end delay values of the plurality of candidate paths. The method may include selecting a path satisfying the end-to-end low delay transmission path.
