Abstract:
System for monitoring the performance of at least one line at a node of a digital communication network, said system including a set of hardware registers associated with said at least one line for registering line performance information associated therewith, a set of counters associated with said at least one line, each counter defining a parameter depending on said line performance information, and a processing unit (16) for, during a predetermined period of time, gathering said line performance information from said hardware registers, computing said parameter and writing the parameters defined by said counters in a performance report to be sent to a network management unit;said system being characterized in that it comprises: at least one line table (22, 24 or 26) associated with said at least one line and storing all the data necessary to read said line performance information from said hardware registers and to compute said parameter for each counter of said set of counters associated with said at least one line; and a processing machine (20) for reading said line table, sequentially computing the parameters defined by each one of said set of counters by using the data stored in said line table, and sequentially updating said counters.
