Abstract
A network processing system is described that is able to monitor IP network traffic, including the ability to perform trap and trace on IP communications flowing over the IP network. The network processing system is able to scan the entire contents of data packets passing through it, and to associate related data packets into discrete sessions, or flows, which allows the network processing system to search for predetermined search criteria contained within those flows. If a flow is found to contain a predetermined search criteria, the network processing system is able to maintain a record of the flow or to replicate the flow and save it or send it to another IP address for monitoring. The monitoring of a flow can include the entire contents of the flow, or any subset of information in the flow such as call identifying information.
