Xena RFC 2544 - Xena Networks

Xena Networks - the Ethernet Test Infrastructure CompanyXena RFC 2544RFC 2544 Benchmarking PackageXena RFC 2544 Software PackageThis package provides automated performance testing of L2/3 networkdevices per IETF RFC 2544, Benchmarking Methodology for NetworkInterconnect Devices. Included in this package are test cases for thefollowing:• Device Throughput by finding the maximum rate at which none of theoffered frames are dropped• Latency by measuring the minimum, average and maximum transmidelay• Frame Loss rate throughout the entire range of rates and frame sizes• Back-to-back frames processing of the network deviceThe test package is delivered as a MS Excel sheet which uses Excel’sembedded Visual Basic for Applications (VBA) language to executescripting command to the Xena testers. All results and graphs are storedin the Excel sheet, from where the user can easily print test reports andcharts, and export test results.Features and Benefits• All RFC 2544 tests over VLANs and IPv4protocols• Test with jumbo frames and verify low-latencyand wire-rate• Large port count and full mesh tests, unidirectionalor bi-directional testing• Easy point-to-point, point-to-multipoint, andmultipoint-to-point testing• Reduce time-to-test through easyconfiguration and fast execution• Summary and comprehensive detailed results• Support for both standard and fully userdefined test configurationThroughput by Frame Size vs Theoretical Max16000000Throughput rate (fps)1400000012000000100000008000000600000040000002000000064 128 256 512 1024 1280 1518Frame Size (bytes)Burst Size (frames)18001600140012001000800600400Theoretical ThroughputThroughputMaximum Burst by Frame SizeBurst size (frames)200064 128 256 512 1024 1280 1518Frame Size (bytes)www.xenanetworks.comXENAN E T W O R K S

Frames are initially sent at a user-specified rateand a binary search algorithm is used to obtain a rate at which the DUT does not loseframes. Frames can be MAC only or IPv4. Results include throughput rates in frames persecond obtained for each frame size.The Latency test determines the latency of the DUT. In the Latency test, frames aretransmitted for a fixed duration. Frames are transmitted and tagged with timestamps.Latency is calculated by subtracting the transmit timestamp from the receive timestamp.Frames can be MAC only, or VLAN/Q-in-Q/IPv4/UDP. Results include latencies for eachframe size and the average, minimum, and maximum latencies for all thetrials.The Frame Loss Test determines how many frames the DUT loses at various frame rates.The number of frames to transmit is specified along with the initial transmit rate, and thepercentage decrease in the frame rate for each iteration. Frames can be MAC only, or IPv4.Results include frame loss at various rates for each frame size.The Back to Back Test determines the maximum time that the DUT can receive andforward without frame loss. Frames are sent at a user-specified rate, generally themaximum theoretical rate based on the speed of the port. The results of the test show thenumber of back-to-back frames obtained for each frame size and the average and totalback-to-back frames for all the trials. Frames can be MAC only, or IPv4. Results includetotal back to back frames without loss for each frame size.XENAN E T W O R K Swww.xenanetworks.comSales contact: sales@xenanetworks.com© Xena Networks — 2012-03-01
