Abstract:
1. A method for sizing one or more transponder pools in a dynamic wavelength division multiplexing optical network having a plurality of nodes, each transponder pool associated with an associated node of the network, comprising steps of: performing network simulations; generating transponder pool histograms for each associated node based on the network simulations; performing statistical analysis using the transponder pool histograms to verify probability distribution is from Chi-Squared family, to determine probability distribution parameters for each associated node and to calculate where, on the horizontal axis of the probability distribution, a tail area of a desired blocking starts; sizing the transponder pools in accordance with where the desired distribution tail area starts; executing network call blocking simulations to determine call blocking probabilities; determining whether the call blocking probabilities meet blocking requirements; when the blocking requirements are met, using the sized transponder pools; and when the blocking requirements are not met, adjusting where the desired distribution tail area starts and repeating the steps of sizing the transponder pools, executing the network call blocking simulations and determining whether the call blocking probabilities meet the blocking requirements.
