Methods, systems, and computer readable media for impairment testing using an impairment device

Abstract:

According to one method, the method occurs during a test session for testing a system under test (SUT) and at a network test system comprising physical application-specific integrated circuit (ASIC) switching resources, wherein the network test system emulates a data center switching fabric comprising virtualized data center switching fabric elements: transmitting, to an inline impairment device, a test packet via an egress portion of an external physical port interface associated with the network test system, wherein the inline impairment device is connected via the external physical port interface associated with the network test system; receiving, from the inline impairment device, an impaired packet via an ingress portion of the external physical port interface associated with the network test system, wherein the impaired packet is generated when the impairment device applies at least one impairment to the test packet; and transmitting, using one or more of the virtualized data center switching fabric elements, the impaired packet to the SUT.
