Tagged data routing path determining device for communication network, has treatment unit for calculating possible path between outgoing and destination node to find ideal path with respect to performance of paths on criterions

摘要

The device has a memory unit (M1, M2) for stocking a table correspondence between a service data set and an information data representative of two criterions. A treatment unit calculates possible path between an outgoing (LER1) and destination node for finding an ideal path with respect to a performance of the paths on the criterions. The treatment unit associates the data route flow with a tag representative of the ideal path. The treatment unit receives a query of establishment of the path containing the set and assures a connectivity of network nodes with respect to the data for calculating the possible path. An Independent claim is also included for a tag switching router for a communication network.
