Abstract
In global communications the demand for higher bandwidth is increasing phenomenally due to the spread of Internet in particular and other domain applications in general. Legacy networks are existing networks which are in implementation. Continuity can be achieved through Optical backbone networks only, even though other media, such as satellite are available in public switched telephone networks, the interface between client and network is an optical Asynchronous Transfer Mode (ATM) switch. Wavelength division multiplexing provides efficient bandwidth utilization. Dense wavelength division multiplexing uses multiplexers at the transmitter at different wavelengths. Availability of contiguous wavelength in the route should be considered for optimum utilization of routing algorithm. In terms of routing packets in optical domain, QOS parameters that need to be considered for optimization are Packet Size, Throughput, Traffic Density, Data Rates and BER. This paper deals with understanding the parameters for various algorithms for duplex/bidirectional multiple packet transmission through asynchronous transfer mode (ATM) protocol. Here ATM acts as a switch for routing algorithm. Fixed Size ATM Packets are transmitted to optimize throughput in the network. NETLOGO software is used for simulation and analysis.
