Abstract:To diplomsko delo predstavlja problematiko usmerjanja in dodeljevanja valovnih dolžin v optičnih omrežjih z valovnodolžinskim multipleksiranjem in z zmožnostjo optičnega obvoda. Začetek dela opisuje delovanje, zgradbo in lastnosti takšnih omrežij ter izpostavi nekatere pomembne dejavnike, s katerimi se v njih pogosto soočamo, na primer regeneracijo, združevanje prometa ter zaščito poti. V jedru dela je obravnavan problem usmerjanja in dodeljevanja valovnih dolžin za statičen in dinamičen promet. Predstavljene so hevristične metode, s katerimi problem najpogosteje rešujemo. Opisan je simulacijski program Hegons ter kako smo z njim opravili simulacijo in primerjavo posameznih hevrističnih metod.

Title:ROUTING AND WAVELENGTH ASSIGNMENT IN WDM OPTICAL NETWORKS
Abstract:This diploma thesis introduces the routing and wavelength assignment problem in wavelength-division-multiplexed optical networks with optical bypass capability. The beginning of the thesis describes the operation, structure and properties of such networks, and also puts forward some important factors which we commonly face when dealing with such networks, for example regeneration, traffic grooming and path protection. The core of the thesis discusses the routing and wavelength assignment problem for static and dynamic traffic. Presented are heuristic methods which are usually used to solve the problem. The thesis also describes the optical network simulator called Hegons and the way we carried out the simulation and comparison of the various heuristic methods.
Keywords:optical network, wavelength-division multiplexing, optical bypass, regeneration, grooming, path protection, routing and wavelength assignment
