Claims
- 1. A method of improving sparing efficiency in a telecommunications network in which the telecommunications network has at least one forcer span that has a deleterious effect on sparing efficiency and in which the nodes in at least part of the telecommunications network are configured as a mesh network, the method comprising the steps of:identifying a forcer span in the telecommunications network; finding a placement of a ring in the telecommunications network that reduces the deleterious effect of the forcer span; and integrating the ring into the telecommunications network.
- 2. The method of claim 1, in which integrating the ring into the network makes the forcer span a non-forcer span.
- 3. The method of claim 2, in which finding a placement of a ring that reduces the deleterious effect of the forcer span comprises evaluating plural ring placements based on the cost of placing each ring in the network.
- 4. The method of claim 3, in which a ring is selected for placement in the network that is the most cost effective of the ring placements evaluated.
- 5. The method of claim 3, in which integer programming is used to evaluate the ring placements.
- 6. The method of claim 3, in which a heuristic is used to evaluate the ring placements.
