| Popis: | This paper describes a ‘state-of-the-art’ network planning tool-kit for core transmission systems. The tool-kit has been used extensively within the BT Group over the past 5 years to provide a forward-looking view of the capacity requirements based on a rolling two-year forecast for the BT core transmission narrowband and broadband networks. The tool-kit also has the capability to perform ‘retrospective’ design as well as evolve the design of new networks — the only constraint being the physical infrastructure, i.e. ducts. The tool-kit provides the capability to audit designs and configuration data proposed by a network supplier. It has an in-built routing engine as well as state-of-the-art optimisation algorithms that have been applied to SDH and ATM, as well as optical WDM-based networks. Application of this functionality has had an inpact on key strategic decisions to the value of around a £15–20M saving within the BT Group over the past two years alone. |
