Network consolidation - how to improve the efficiency of provisioning oriented optical networks

Fast provisioning capabilities enabled by signalling intelligence and automated switching flexibility are becoming fundamental features of Next Generation Networks based on optical transport. Throughout the recent years numerous research and development projects, standardisation activities, and a large number of publications have been devoted to fast provisioning enabled optical networks. However, in the related research activities less attention has been paid to network state evolution during the provisioning process. The main scope of the paper is, based on a three-phase network development lifecycle, to define different consolidation strategies in order to improve the performance of provisioning oriented optical networks. The proposal is motivated by the inherent lack of capacity efficiency of optical channel provisioning processes. OCIS codes: 000.1200, 060.0060. 1 The research work presented in this paper has been initiated in the framework of Italian-Hungarian InterGovernmental Project I-17/04 titled "Planning and Implementing Reliable IP over WDM Optical Networks", and partially granted by OTKA 048985 Project titled "Dimensioning and reliability analysis of fault-tolerant networks in Differentiated Reliability (DiR) environment". The author wishes to thank the anonymous reviewers for their helpful comments and suggestions.
