METHOD AND NETWORK NODE FOR SELECTING A COMBINING POINT

摘要

The present invention relates to a method and network device for selecting a combining point at which at least two redundant transmission paths are combined to a single transmission path in a transmission network comprising at least two select-able combining points (B - J). The combining point is selected by a method using at least two measurement-based selection criteria to which different priorities are allocated. The selection result of a selection criterion with a higher priority is used as a constraint for a selection based on a selection criterion with a lower priority. The selection criteria are applied to lengths or loads of the redundant transmission paths or the single transmission path. Thereby, an optimized combining point can be obtained to thereby lower delays for combined traffic and increase efficiency of network utilization.
