  • Patent number: 12231410
    Abstract: Methods, systems, and computer readable media for processing QUIC communications in a network. An example system includes a first network interface for receiving a QUIC connection request from a first node in the network and, in response, establishing a first QUIC connection between the first node and the system. The system includes a QUIC processing module configured for receiving, via the first QUIC connection, encrypted QUIC data including a number of streams and decrypting the encrypted QUIC data, resulting in decrypted QUIC data. The QUIC processing module is configured for extracting each of the streams from the decrypted QUIC data, resulting in a plurality of extracted streams, and packaging at least one of the extracted streams into a non-QUIC protocol format, resulting in at least one packaged stream. The system includes a second network interface for transmitting the packaged stream to a second node in the network.

  • Patent number: 9253242
    Abstract: Methods, systems, and computer readable media for assigning separate dedicated bearers for separate audio and video streams in a test simulation environment are disclosed. In one embodiment, the method includes generating dedicated bearer information associated with each of a dedicated audio bearer and a dedicated video bearer to be used for a communication session and providing the dedicated bearer information to a simulation device. The method further includes, from the simulation device, using the dedicated bearer information to negotiate establishment of the dedicated audio bearer and the dedicated video bearer between the simulation device and a system under test (SUT) and sending simulated traffic data to the SUT over the dedicated audio bearer and the dedicated video bearer in accordance with a mapping based on the dedicated bearer information and identifiers included in the simulated traffic.
