Abstract

Disposizione e metodo per la sorveglianza dei parametri di traffico del flusso di celle ATM secondo il principio cosiddetto "Leaky Bucket" in una terminazione di centrale (ET) comprendente una unità di elaborazione e traslazione dell'header (HTU). Vengono previste diverse unità di sorveglianza o policing (PU1, PU2, PU3, PU4), per il controllo del bit rate di picco (Rp) e medio (Rm), discriminando anche tra le celle appartenenti al flusso ad alta priorità (CLP=0) e quelle appartenenti al flusso a bassa priorità (CLP=1). Le unità vengono attivate in parallelo dalla detta unità di elaborazione e traslazione (HTU) e collegate a una rete combinatoria (RC). In caso di violazione dei parametri contrattati, la cella prioritaria può essere declassata e trattata come le altre a bassa priorità, oppure può venire scartata. L'aggiornamento nelle unità viene eseguito nel ciclo successivo di sorveglianza della cella relativa alla medesima connessione (Fig. 5).
