20.500.12556/DKUM-21922 PRENOS PODATKOV V KABELSKIH DOSTOPOVNIH OMREŽJIH PO STANDARDIH DOCSIS DATA TRANSFER IN CABLE ACCESS NETWORKS USING DOCSIS STANDARDS Namen diplomske naloge je bil proučiti in predstaviti najpomembnejše postopke in rešitve, ki so del mednarodnih standardov za kabelske sisteme DOCSIS. Vsaka nova verzija standardov DOCSIS nadgrajuje obstoječe z novostmi, tako da kabelski operaterji v kabelskem omrežju lahko hkrati uporabljajo naprave, ki podpirajo različne verzije. V nalogi je najprej opisana zgradba hibridnih vlakensko- kabelskih omrežij. Nadaljujemo s prenosom podatkov v kabelskih dostopovnih omrežjih po standardu DOCSIS 1.1, kjer damo največ poudarka razlagi krmiljenja dostopa do prenosnega sredstva. Za DOCSIS 2.0 je omenjen novi, sinhroni kodno porazdeljeni sodostop, za DOCSIS 3.0 pa so prikazane metode združevanja kanalov, ki povečajo zmogljivost rešitev iz starejših verzij standardov DOCSIS. V zadnjem delu je prikazan primer registracije kabelskih modemov, ki smo ga izvedli s pomočjo strežnikov in datotek z nastavitvami, ki temeljijo na standardu DOCSIS 1.0. The purpose of this diploma thesis was to closely examine and present the most important procedures and solutions that are part of the international standards for cable systems, named DOCSIS. Each new version of standards DOCSIS upgrades the existing ones with new features, so that in their cable networks, the cable operators can simultanously use devices which support different versions. In this thesis we first describe the structure of the hybrid fiber-coaxial networks. We continue with data transmission in cable access networks according to standard DOCSIS 1.1, where we emphasise the described topic of the medium access control. For DOCSIS 2.0 we mention the new synchronous code division multiple access, and for DOCSIS 3.0 we explain channel bonding, which increases the efficiency of the solutions from the previous versions of standards DOCSIS. In the last part of the thesis we present an example of cable modem registration that we performed with help of servers and files with their settings based on DOCSIS 1.0. podatkovne komunikacije sodostop zaključni sistem za kabelske modeme kabelski modem krmiljenje dostopa do prenosnega sredstva data communications multiple access cable modem termination system cable modem medium access control true true false [F.
