  • Methods, systems, and computer readable media for software-based emulation of media access control security (MACsec)
    Patent number: 11563773
    Abstract: A method for software-based emulation of media access control security (MACsec) includes generating, using a software-based emulated MACsec packet generator, a plurality of emulated MACsec packets, each of the emulated MACsec packets including a MACsec header having a packet number field value that remains fixed across the emulated MACsec packets. The method further includes configuring a device under test to accept plural MACsec packets with the same MACsec packet number field value. The method further includes transmitting the emulated MACsec packets to the device under test (DUT). The method further includes determining whether the DUT responds correctly to the emulated MACsec packets given a replay protection configuration of the DUT. The method further includes generating test output based on a result of the determination.

  • Methods, systems, and computer readable media for testing a network node using source code for programming a packet forwarding plane of the network node
    Patent number: 10880197
    Abstract: According to one method, the method occurs at a network equipment test device. The method includes receiving one or more source code files for programming a packet forwarding plane of a network node; analyzing the one or more source code files to determine test metadata, wherein analyzing the one or more source code files to determine the test metadata includes identifying source code portions that indicate conditions for rejecting or accepting packets and determining the test metadata based on the conditions; generating, using the test metadata, one or more test plans for testing the network node, wherein the one or more test plans define test packets to be sent to the network node for testing the network node's implementation of the conditions for rejecting or accepting packets; and testing the network node using the one or more test plans.
