Abstract
Impairment units and methods for impairing network traffic. An impairment unit may receive packets from a network and determine an impairment class of each packet from a plurality of impairment classes. Input logic may determine whether or not each received packet will be reordered. A received packet not to be reordered may be stored in a normal traffic FIFO queue uniquely associated with the impairment class of the received packet. A received packet to be reordered may be stored in a reorder traffic FIFO queue uniquely associated with the impairment class of the received packet. Output logic may select a sequence of packets from head ends of the plurality of normal traffic FIFO queues and the plurality of reorder traffic FIFO queues to provide outgoing traffic. A transmitter may transmit the outgoing traffic to the network.
