Method and network node for selecting a combining point
First Claim
1. A method of 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 selectable combining points (B-J), said method comprising the steps of a) using at least two measurement-based selection criteria for selecting said combining point;
- b) allocating different priorities to said at least two selection criteria; and
c) using the selection result of a selection criterion with a higher priority as a constraint for a selection based on a selection criterion with a lower priority.

Abstract
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 selectable 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.

- 27. A network node 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 selectable combining points (B-J), said network node being arranged to use at least two measurement-based selection criteria with different priorities for selecting said combining point, and to use the selection result of a higher priority selection criterion as a constraint for a selection based on a lower priority selection criterion.
