A service level agreement (SLA) monitoring system is provided for making fair determination as to an extent to which an SLA is achieved and for facilitating a procedure taken by a user to receive compensation when the SLA is violated. The monitoring system comprises a plurality of service level probing boxes and a monitoring center. Each of the service level probing boxes, which is installed as an interface between each user network and a provider network, monitors user packets to detect whether the SLA is violated, when the user packets flow from an originating user network to the provider network and when the user packets flow from the provider network to a destination user network, and transmits the result of detection to the monitoring center. The monitoring center conducts fact finding for a violation of the SLA based on information from each of the service level probing boxes, and acts as a procedure for claiming compensation in the name of a user in conformity with an SLA contract.
