Abstract
The error performance of an ATM signaling link operating under the service specific connection oriented protocol (SSCOP) is monitored at the transmitting end of the link by attributing a penalty factor at the end of each polling interval. That penalty factor is determined by whether or not any message was retransmitted in the interval, and whether or not any stat messages transmitted by the receiver in response to each poll were received from the receiver within a predetermined number of polling intervals. At the end of a block of N.sub.-- blk polling intervals, a quality of service (QOS) measure is determined based on the average penalty factor of the block. If the QOS measure is greater than a predetermined threshold, then the link is removed from service. In order to adequately monitor a link with low traffic, the number of stat messages that are are lost within a superblock of N.sub.-- sup polling intervals is determined and if greater than a predetermined number, the link is removed from service.
