Abstract
This work studies the performance of a proposed high-speed optical fiber local area network based on wavelength division multiplexing (WDM) and asynchronous transfer mode (ATM). The design optimizes the usage of resources by assigning different types of traffic to two overlapping sub-networks. The WDM segment is a circuit-oriented network for high-speed traffic. The ATM sub-network handles control, low speed traffic and overflows of the WDM network. Each network is supported by one of two types of channels. The ATM channel employs conventional ATM cells for all stations using a 1300-nm wavelength carrier. The WDM channel which is assigned dynamically for very high-speed applications operates at 1500 nm band. The application of an ATM network to handle the overflow traffic reduces blocking in the system by approximately 13% for a 32 WDM system. However, depending on the load, it may increase the delay between 5% to 30%. In addition, employing an adequate queuing policy, we may reduce the blocking by 30% while increasing the delay by 5%. We may conclude that the network is more efficient handling the traffic load compared to a simple circuit switched WDM network.
