Simulate High Traffic and Effective Cost an Academic Kurdistan Network   Based on DWDM using OPNET
  Till now the academic institutes in Kurdistan region not connected via network with each other and with research centers worldwide, this paper suggests design an optical IP-Network for academic Kurdistan region based on DWDM (Dense wavelength Division Multiplexer) backbone. The design has been developed using minimum spanning tree between the main realistic locations for campuses in each province were calculated using Prim's algorithm in province level. This proposed network simulated using OPENT IT GURU, and then information was collected using GPS and GIS about the campuses (to obtain realistic locations) of each university in university level, finally unique design model was assumed for each campus in campus level. Simulation the proposed design shows results of delay, traffic sends, traffic receives; utility, performance (packet/second) and throughput are measured in the case of heavy load. Addition to that the hub based network has longer response time than the switch based network. Key words: IP-Network, OPNET, DWDM, Prim's algorithm, Intranet, GPS and GIS.
