Abstract

An automatically configurable network monitoring system includes a network monitoring communications protocol used for communications between a network monitoring client executing on a routing node (100) being monitored and a network monitoring server executing on a network monitoring processor (106). According to the network monitoring communications protocol, the network monitoring client broadcasts a network monitoring service request message to the network monitoring servers. The service request message identifies a signaling link for which network monitoring service is being requested. The network monitoring servers provisioned to the requested provide network monitoring service respond affirmatively and thereby automatically grant network monitoring service. The network monitoring system may be completely probeless or, alternatively, used in conjunction with probe-based network monitoring devices.
