I servizi di un livello (o di un sottolivello) sono le operazioni che questo è in grado di svolgere su richiesta del livello immediatamente superiore; nell’eseguire le operazioni di sua competenza, tale livello fa a sua volta riferimento ai servizi offertigli dal livello inferiore. Nella gerarchia di un’architettura a tre livelli, come descritta dalla CEI EN 1334-4-1, il sottolivello del controllo di collegamento logico (LLC) si colloca tra il livello applicativo ed il sottolivello di controllo dell’accesso al mezzo di comunicazione (MAC). Il protocollo di comunicazione dati (DCP) del sottolivello LLC, che viene descritto dalla presente Norma, tratta dei servizi che un’entità del sottolivello LLC svolge per il livello applicativo, e di quelli che a sua volta richiede al sottolivello MAC. I servizi sono descritti in forma astratta, specificando il flusso di informazione tra i livelli, e cioè precisando le primitive ed i parametri che caratterizzano ciascun servizio. Tali primitive sono associate a una trasmissione del tipo senza connessione.
La presente EN viene pubblicata dal CEI nella sola lingua originale inglese, a causa della limitata utilizzazione, particolarmente mirata a settori specialistici.
