  • Patent number: 11831763
    Abstract: Methods, systems, and computer readable media for utilizing predetermined encryption keys in a test simulation environment are disclosed. In one embodiment, a method includes generating, prior to an initiation of an Internet protocol security (IPsec) test session, a private key and a public key at a traffic emulation device and storing the private key and the public key in a local storage associated with the traffic emulation device. The method further includes retrieving, from the local storage, the private key and the public key upon the initiation of the IPsec test session between the traffic emulation device and a device under test (DUT) and generating a shared secret key utilizing the retrieved private key and a DUT public key received from the DUT.

  • Patent number: 10212125
    Abstract: The subject matter described herein relates to methods, systems, and computer readable media for testing network equipment devices using connection-oriented protocols. In some examples, a method for testing a network equipment device under test (DUT) includes executing, by a network equipment test device, a test script to test the network equipment DUT using a connection-oriented protocol. The method includes inserting, during a connection establishment process of the connection-oriented protocol for a network flow to the network equipment DUT, a flow-identifying sequence number into a sequence number field of a first message of the network flow. The flow-identifying sequence number is a number uniquely identifying the network flow from other network flows. The method includes receiving a second message from the network equipment DUT and determining that the second message belongs to the network flow by extracting the flow-identifying sequence number from the second message.

  • Patent number: 9219667
    Abstract: Methods, systems, and computer readable media for selectively processing packets using time to live (TTL) information are disclosed. A method for selectively processing packets using TTL information includes receiving, at a test system, a test packet from a device under test (DUT), wherein the test packet includes a TTL parameter field containing a TTL value. The method further includes determining if the TTL value in the test packet is a magic TTL value and performing a processing task on the test packet if the test packet includes the magic TTL value.
