PacketBroker (Packet capture, filtering, aggregation, and modification).RFC 2544 Testing (Throughput, Latency, Frame Loss, and Back-to-Back Tests).The test tool supports multiple functionalities – For PacketExpert™ 10G or 10GX, the RFC 2544 test can be done either on Port #1 or Port #2 at a time and it is not possible to run RFC 2544 test on both the ports (Port #1, Port #2) simultaneously.For PacketExpert™ 1G, the RFC 2544 test can be done either on Port #2 or Port #3 at a time and it is not possible to run RFC 2544 test on both the ports (Port #2, Port #3) simultaneously.The test is setup such that the traffic is transmitted on 10G/1G ports and the PacketExpert at the DUT end can be configured to loop the traffic back on the same port measuring the Tx and Rx time thus calculating the latency In Single port RFC 2544 test, the PacketExpert™ allows Ethernet Throughput, Latency, Frame Loss, and Back-to-Back performance tests in accordance with RFC 2544 specifications on 10G/1G ports. The test is setup such that the traffic can be generated and transmitted on either of the dual ports and the looped back traffic from the DUT is received on the opposite port validating the test parameters.

In Dual port RFC 2544 test, PacketExpert™ allows Ethernet Throughput, Latency, Frame Loss, and Back-to-Back performance tests in accordance with RFC 2544 specifications on 10G/1G ports.

Back-to-Back - It measures the maximum number of frames received at full line rate before a frame is lost.

Frame Loss - Measures the network’s response in overload conditions.

Latency - Measures the time required for a frame to travel from the originating device through the network to the destination device.Throughput - Maximum number of frames per second that can be transmitted without any error.RFC 2544 network testing includes the following types of measurements: RFC 2544 gives testing details for different kinds of LANs Ethernet, 16 MB Token Ring, FDDI.

Networks referred in RFC 2544 can be Local Area Networks (LAN) or Wide Area Networks (WAN). It defines a set of 4 tests - Throughput, Latency, Frame Loss Rate, and Back-to-back frames. RFC 2544 defines a specific set of tests that can be used to evaluate equipment performance. PacketExpert™ supports Throughput, Latency, Frame Loss and Back to Back tests as specified in RFC 2544.
