An algorithmic approach to ETSI partial access STM-16 SNCP-ring design

The increased demand for distribution of telecommunication services over survivable network architectures led to the identification of resilient ring architectures, such as the ETSI developed rings employing subnetwork connection protection (SNCP-rings), as a very desirable network option. With the development of partial access systems in SNCP-rings numerous complex solutions can be achieved in the design of survivable SDH subnetworks. In this paper, an algorithmic approach to the design of partial access STM-16 SNCP-rings is presented and analysed. Eight algorithms for optimising the planning of equipment cost-effective SDH subnetworks using SNCP-ring solutions have been implemented. Results, indicating the efficiency of the algorithms and the factors affecting it, supported by simulation work, are presented and discussed
