1. A system for monitoring a communication session between an originating router and a destination router, comprising:

  • a means for periodically transmitting a state query Telnet message to the originating router, the state query Telnet message including a request for internal router information data;

    a means for receiving, at a node server coupled to the originating router, state information data from the originating router in response to the state query Telnet message;

    means for converting and storing the state information data as a Management Information Base (MIB)-like object;

    means for monitoring the MIB-like object to detect a change in the state information data where the monitoring means includes;

    a means for time-stamping the state information data upon detecting a change in the state information data; and

    a means for transmitting the time-stamped state information data and the session event message; and

    a means for logging a session event when the monitoring means detects the change in the state information data, wherein the logging means resides in an event server coupled to the node server and wherein the logging means includes;

    a means for transmitting a Simple Network Management Protocol (SNMP) message from the event server to the node server;

    a means for receiving state information data in response to the SNMP message; and
