CATZ (CAPACITY ALLOCATION WITH TIME ZONES): A METHODOLOGY FOR COST-EFFICIENT BANDWIDTH ALLOCATION AND RECONFIGURATION IN A WORLD-WIDE WDM NETWORK

摘要

We propose and investigate the characteristics of a bandwidth allocation and reconfiguration method, called CATZ, that exploits the daily traffic fluctuations and time-zone-based traffic shifts to cost-effectively operate a world-wide WDM backbone network.
