摘要：An accurate estimation of network performance is critical for the success of optical networks design. Traffic modeling and availability modeling for optical network are at heart of optical network design. Traffic models and availability models need to be accurate and able to capture the statistical characteristics of the actual traffic and the ability of a network to sustain failures. However, conventional traffic models are limited to characterize the traffic only in a single cell. Similarly, conventional availability models are limited to characterize the network availability only in a length of the link and the hardware equipment failure rate. They do not consider the spatial variation of the network availability within the urban or rural area. In this paper, a novel network traffic model and availability model based on the geographic information system (GIS) has been proposed. The approach can design accurate network traffic and availability models, not only the amount of a network node's add/drop traffic and the amount of the network component failure are regarding, but also their geographic distribution
