摘要： An impairment unit, method, and machine readable storage media for emulating network impairments. A first network interface may receive network traffic including a plurality of received packets. A classifier may determine an impairment class of each received packet based on test information contained within a payload portion of each received packet, the impairment class of each received packet being one of a plurality of impairment classes, each impairment class uniquely associated with a corresponding one of a plurality of impairment profiles. An impairment engine may impair each of the plurality of impairment classes in accordance with the corresponding impairment profile to provide impaired network traffic. A second network interface may transmit the impaired network traffic to the network.

摘要： An apparatus to generate test traffic for testing a network. A scheduler may provide packet definition data for a sequence of packets, each packet associated with a respective flow control group. A channelized schedule FIFO (first-in first-out) queue may store the packet definition data. The channelized schedule FIFO queue may include multiple parallel channels, each channel dedicated to storing packet definition data associated with a corresponding flow control group. A plurality of non-channelized packet builder lanes may build packets in accordance with packet definition data read from the channelized schedule FIFO. A channelized output FIFO buffer may store packets built by the plurality of packet builder lanes. The channelized output FIFO buffer may include multiple parallel channels, each channel dedicated to storing packets associated with a corresponding flow control group. An output multiplexor may interleave packets from the channelized output FIFO buffer to form the test traffic.

摘要： An impairment unit, method, and machine readable storage media for emulating network impairments. An impairment unit may include a network interface to receive network traffic from a network and to transmit impaired network traffic to the network. An impairment engine may generate the impaired traffic based on the received network traffic, the impaired network traffic including at least some duplicate packets. The impairment engine may determine a bandwidth available for transmission of duplicate packets based on the received network traffic and may constrain the total length of the duplicate packets to fit within the available bandwidth.

摘要： 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.

摘要： A traffic signal light having high technology sensors sensing a plurality of conditions proximate the traffic signal light. The sensors may include an acoustic detector, a radiation control monitor, a chemical biological mass spectrometer, a gas detector and an accelerometer. The present invention finds technical advantages in that these high technology sensors can be discreetly sealed in a traffic light housing cavity and hidden from public view, while providing increased security in geographical locations having control signal lights. These high technology sensors may also be disposed outside the traffic light housing cavity.
