  • Patent number: 10278087
    Abstract: The subject matter described herein includes methods, systems, and computer readable media for correlating, load balancing and filtering tapped GTP and non-GTP packets. One method for correlating, load balancing and filtering tapped GTP and non-GTP packets includes receiving GTP packets tapped from a plurality of GTP network tap points. The method further includes receiving non-GTP packets tapped from at least one non-GTP network tap point. The method further includes correlating GTP packets with non-GTP packets for a particular subscriber. The method further includes forwarding the GTP packets and non-GTP packets correlated for the particular subscriber to a network monitoring tool.
    Type: Grant

  • Patent number: 9961588
    Abstract: The subject matter described herein relates to methods, systems, and computer readable media for test system connection resiliency. In some examples, a method for distributing monitored network traffic includes monitoring S1-MME traffic and S6a traffic in a core network of a telecommunications network. The method includes decrypting encrypted S1-MME traffic using information extracted from the S6a traffic. The method includes load balancing between a plurality of monitoring nodes using the decrypted S1-MME traffic.

  • Patent number: 9577669
    Abstract: Methods, systems, and computer readable media for optimized message decoding are disclosed. According to one exemplary method, the method includes receiving a message containing one or more information elements (IEs). The method also includes determining a length associated with the message. The method further includes determining, using the length associated with message, whether the message can be accurately decoded using a mask stored in a memory. The method also includes in response to determining that the message can be accurately decoded using the mask, decoding the message using the mask.

  • Patent number: 9253071
    Abstract: A network equipment device test system includes a message blueprint data structure for storing blueprint data for messages to be decoded. The network equipment test device further includes a message decoder for decoding received messages by accessing the message blueprint data structure and matching information elements in the received messages with information elements in the message blueprint data structure. The network equipment test device further includes a message blueprint data structure configurator for receiving, as input, test configuration data, and for configuring the message blueprint data structure for optimized decoding of messages based on the test configuration data.
