  • Patent number: 10469364
    Abstract: Internet protocol packets are statelessly identified as associated with a particular session-instance by identifying a key, or session-instance identifier, within the data (or payload) portion of a user plane packet. This identifier is specific to the session-instance and remains constant throughout the session-instance. Using this stateless identification, transmitted user plane packets are automatically routed at the transmission speed of the transmission link using a method that automatically balances the analysis processing load between network probes. The load is balanced by routing the user plane packet to a network probe that is either already analyzing the session-instance or by routing the user plane packet to a system that has processing capacity to analyze a new session-instance. The network probe then analyzes the user plane packet and the session-instance to measure the quality of the user experience of the session-instance and performance of the network.

  • Patent number: 10284440
    Abstract: A network monitoring system that summarizes a plurality of data packets of a session into a compact session record for storage and processing. Each session record may be produced in real-time and made available during the session and/or after the termination of the session. Depending on protocols, a network monitoring system extracts different sets of information, removes redundant information from the plurality of data packets, and adds performance information to produce the session record. The network monitoring system may retrieve and process a single session record or multiple session records for the same or different protocols to determine cause of events, resolve issues in a network or evaluate network performance or conditions. The session record enables analysis in the units of session instead of individual packets. Hence, the network monitoring system can analyze events, issues or performance of the network more efficiently and effectively.
