An algorithmic approach for the planning of partial access ETSI SDH SNCP-ring subnetworks

With the development of rings employing subnetwork connection protection (SNCP-rings) numerous complex solutions can be realised in the design of survivable synchronous digital hierarchy (SDH) networks. Three algorithms for optimising the planning of equipment cost-effective SDH networks using SNCP-ring solutions have been implemented. Results indicating the efficiency of the algorithms and the factors affecting this efficiency, supported by simulation work, are presented and discussed.
