Four key economic and operational benefits from mesh optical networking are discussed. They are (1) end-to-end routing and provisioning, (2) fast and capacity-efficient restoration, (3) re-provisioning, and (4) re-optimization. They contribute in various ways to network cost savings and higher network and service reliability in mesh networks compared to traditional ring-based networks.
This paper presents a collection of approximation formulas that allow a network planner to quickly estimate the size of a mesh optical network with limited inputs. In particular, it provides a set of equations that relate number of sites, average fiber connectivity, demand load and capacity for various mesh protection architectures. These results can be used to easily and quickly estimate the amount...
