Abstract
A method of monitoring a network with a test device connected to the network includes monitoring a plurality of packets which pass through the test device, comparing a predefined field of each of the plurality of packets to a predefined pattern so as to identify signature packets, evaluating whether the signature packets satisfy a predefined condition, and, if the predefined condition is satisfied, sending a notification to a user. A system implementing the method is provided.
Claims15
A method of monitoring a network with a test device connected to the network, comprising:
- monitoring a plurality of packets which pass through the test device,
- comparing a predefined field of each of the plurality of packets to a predefined pattern so as to identify signature packets,
- evaluating whether the signature packets satisfy a predefined condition, and, when the predefined condition is satisfied, sending a notification to a user.
A system for monitoring a network, comprising:
- a plurality of sensors, each programmed to capture a plurality of packets passing therethrough, and a monitoring manager programmed to send a notification to a user;
- wherein the system is programmed to
- (a) compare a predefined field of each of the plurality of packets to a predefined pattern stored in a tangible memory so as to identify signature packets,
- (b) evaluate whether the signature packets satisfy a predefined condition, and,
- (c) send the notification if the predefined condition is satisfied;
- and,
- wherein either the sensors are programmed to perform steps (a) and (b), or the monitoring manager is programmed to perform steps (a) and (b), or the sensors are programmed to perform step (a) and the monitoring manager is programmed to perform step (b).
