Patent ID: 11108675

Abstract:
Methods, systems, and computer readable media for testing effects of simulated frame preemption and deterministic fragmentation of preemptable frames in a frame-preemption-capable network are disclosed. According to one method, a device under test including at least one processor simulates frame preemption by generating a plurality of simulated preempted frame fragments and an express frame. The test device deterministically orders, independently from MAC merge sublayer fragmentation and ordering, the simulated preempted frame fragments and the express frame for transmission to the DUT. The test device transmits the simulated preempted frame fragments and the express frame to the DUT in an order corresponding to the deterministic ordering. The test device receives a response of the DUT to the simulated preempted frame fragments and the express frame. The test device determines, based on the response of the DUT, whether the DUT operates in accordance with specifications for frame preemption.
