2 Network Testing with the FrameScope Pro

NOTE

Performing RFC 2544 Tests

RFC 2544 tests consist of the round-trip latency test, the point-to-point throughput test, the frame loss rate test, and the back-to-back test.

If the slave FrameScope Pro is in use, an autosearch from the master FrameScope Pro will result in Search Failed. A manual search by keying in the IP address of the slave FrameScope Pro on the master FrameScope Pro will result in Remote Busy.

RFC 2544 Throughput Test

This test determine the maximum throughput rate for different frame lengths between two network points with no frame loss in frames/s, bits/s, or percentages.

The test sends frames at a constant rate in either unidirectional or bidirectional, for a fixed number of seconds. A search is conducted to determine the maximum frame rate that can be forwarded by the network with no loss. The search is capped by the maximum data rate, either user-defined or based on the media maximum rate. If the frame is dropped during the bidirectional symmetrical test or the loopback mode, regardless of the direction, the test will rerun at a lower rate and the result will be a single throughput value. On the other hand, the bidirectional asymmetrical test will measure the throughput rate for each direction. If the number of transmitted frames does not match the number of received frames by t he other side, the transmit level will be reduced. The test procedure repeat for different range of legal frame lengths to produce a table of maximum throughput versus frame length.

For better results, adjust the duration to load the device under test sufficiently.

RFC 2544 Round-Trip Latency Test

This test measures the latency experienced by a frame passing and looping back through the network. A tagged frame is sent and the time that the tagged frame exits and loops back to the FrameScope Pro is recorded. Round-trip latency is the difference between the entrance and exit times of the tagged frame. The latency reports an average of at least 20 trials. The test is conducted over a range of frame sizes.

50 N2620A User’s Guide

For better results, adjust the duration to load the device under test sufficiently.

RFC 2544 Frame Loss Rate Test

This test measures the percentage of frames that the network devices did not forward due to lack of resources for entire range of frame length and data rates.

For a specific frame length, traffic is sent at the maximum rate (100% load). The number of frames received is compared against the number of frames transmitted and is shown as a percentage of frames forwarded by the network. The data rate is reduced by a step size of 10% (the step size is configurable), until two successive measurements without a single frame loss or until 10% traffic level (the lowest step size) is reached.

The test is conducted over a range of frame lengths. The test can be performed in either loopback, unidirectional, or bidirectional mode. Loopback mode is similar to bidirectional test, with the only difference being the destination is a loopback device instead of another FrameScope Pro.

Network Testing with the FrameScope Pro 2

For better results, adjust the duration to load the device-under-test sufficiently.

RFC 2544 Back-to-Back Test

This test measures the maximum number of back-to-back frames that the network can transfer without loss.

For a specific frame length, a burst of back-to-back frames is sent to a destination device through the network. Similar to the throughput test, a binary search of burst sizes is done to find the maximum burst size that can be forwarded by the network with no frame loss. The trial length must be at least 2 s and the results of at least 50 trials should be averaged for the displayed value. The test is conducted over a range of frame lengths.

The test can perform in either loopback, unidirectional, or bidirectional mode. Loopback mode is similar to bidirectional mode, with the only difference being the destination is a loopback device instead of another FrameScope Pro.

For better results, adjust the duration to load the device-under-test sufficiently.

2 Network Testing with the FrameScope Pro

Setting the Network for RFC 2544 Tests

The network settings have to be adjusted to ensure that the test can run.

• NAT has to be disabled or the IP and MAC addresses of the FrameScope Pro should be allowed to pass through.

• Firewalls have to be disabled or should allow the IP and MAC addresses of the FrameScope Pro to pass through.

• ICMP ports need to be freed up for the network-under-test (for information request and reply).

• UDP ports 7 (slave UDP port) and 7777 (master UDP port) needs to be vacated for the network-under-test.

• During an RFC2544 test, the FrameScope Pro has a default timeout duration after a MAC reset. If the peer does not respond within the stipulated time, the RFC 2544 test will not start and will result in a timeout. Different switches may have different response times after a MAC reset. You should select a suitable and appropriate timeout period for the switches-under-test with reference to the equipment requirements as supplied by the supplier or vendor.

Performing Packet Error Rate Tests

The Packet Error Rate Test (PERT) generates traffic to the network and measures frame loss and frame error rate. The test can be performed between two FrameScope Pro units or between one FrameScope Pro and a loopback device. The supported test directions are downstream, upstream, sequential (when the test port is half duplex), or bidirectional (when the test port is full duplex).

Packets that are received by the receiving side are analyzed for checksum errors and losses. PERT captures errors in all segments of the Ethernet frame, including both the header and payload. PERT can also analyze the network response to the errors by injecting the errors into the network. The configurable parameters for the test are as listed below.

• Target (another FrameScope Pro, or a loopback device)

• Frame length in bytes (64 bytes to 16000 bytes)

Network Testing with the FrameScope Pro 2

• Frame rate

• Utilization percentage of the port speed

• Test duration in hours:minutes, or continuous

• Timeout

• Test direction

• Data pattern (choice of six preconfigured and custom

patterns)
