METHOD FOR ESTABLISHING ON-DEMAND ROUTE AND NETWORK NODE DEVICE

摘要

PROBLEM TO BE SOLVED: To enable routings to meet the delay requirements of different applications to reduce the consumption of network bandwidth.SOLUTION: The present invention relates to the field of network communication technologies. A method, an apparatus and a system for building on-demand routings are provided. The method includes the steps of: determining that stable routings need to be built (101); building the stable routings and recording in a routing table routing entries corresponding to the stable routings (102); determining the valid time of the stable routings which is longer than that of other ordinary routings (103); and aging the routing entries according to the valid time of the stable routings (104).
