Abstract

Svako korištenje zajedničkog medija u komunikacijskim sustavima zahtijeva odgovarajući protokol koji upravlja pristupom. U optičkim mrežama temeljenim na valnom multipleksu zajednički medij predstavljaju raspoložive valne duljine. Tema ovog rada su protokoli višestrukog pristupa koji upravljaju pristupom čvorova valnim duljinama sustava. U radu su detaljno analizirana četiri pristupna protokola: I-SA (Interleaved Slotted ALOHA), I-TDMA (Interleaved Time Division Multiple Access), I-TDMA* (Interleaved Time Division Multiple Access Star) i TDMA-C (Time Division Multiple Access Collisionless). Izrađen je simulator pomoću kojega su promatrane najznačajnije karakteristike sustava: ukupna propusnost i prosječno kašnjenje okvira u sustavu. Rezultati simulacija prikazani su u obliku grafova i analizirani.

Abstract (english)

Communication systems often use a shared medium. Access to that medium requires a protocol. Communication systems based on wavelength division multiplexing use many wavelengths, each representing a distinct channel. This paper examines media access control protocols for such WDM networks. The paper presents four access protocols: I-SA (Interleaved Slotted ALOHA), I-TDMA (Interleaved Time Division Multiple Access), I-TDMA* (Interleaved Time Division Multiple Access Star) and TDMA-C (Time Division Multiple Access Collisionless). The simulator has been built and used to measurs network throughputs and average packet delays. Gathered results were displayed and analyzed.
