• Increased the number of virtual stations (vSTA) that can be used with the test system​:
  • Provides the ability to test large capacity stations in test cases designed to stress a DUT.
• Expanded 802.1x authentication support​
• Support for MBSSID:​
  • Offers service for multiple networks, with same hardware. Because it's the same hardware and the same frequency range, users on one network share with users on another network using the same hardware.​
• Bridging for Pal-6/Pal-6E to allow for external traffic integration
• DSCP enablement for iPerf2
• Channel 12 and 13 support

RFC 2544 contains a specific set of benchmark tests built around the widely supported RFC 2544 industry specification that can be used to evaluate network interconnecting device performance. This automation package is comprised of 4 tests: Throughput, Latency, Frame Loss Rate, and Back-to-back frames.

Four basic tests iterating frame sizes; 64, 128, 256, 512, 1024, 1280, 1518 for uplink and downlink. Multiple station traffic groups for all test cases with offered load adjustment calculated to limit frame loss.

Throughput (Most popular test)

• Throughput is denied in RFC 2544 as the fastest rate at which the count of test frames transmitted by the DUT is equal to the number of test frames sent to it by the test equipment.
• Another way to think about this test is that it measures the rate at which the Device Under Test (DUT) is able to perform at with 0% packet loss.

Back-to-back

• This test permits vendor (DUT) behavior with burst traffic, or better known as “buffered operations.”  The back-to-back value is the number of frames in the longest burst that the DUT will handle without the loss of any frames.

Frame Loss

• This test uses the determined maximal frame rate from the throughput test. It should always be run in conjunction with the throughput test. The offered load is reduced until the percent packet loss is 1%.

Latency

• Latency is the delay between the frame being sent and its reception on the other end of the measured link. Latency is measured at the determined throughput of the device for a given frame size.

Mesh AP Systems are becoming an increasingly popular solution to deliver broadband internet throughout a home or an office. Currently, there is no standard yet that covers this space. Spirent has taken the lead and created a specific Mesh automation package to address a unique set of test cases to describe the performance of a Mesh system.

The Mesh Automation Packages characterizes the mesh in terms of the level of service that it delivers to the end user. The automation package simulates real, recorded homes in the lab. The testing is performed using a black box testing principle: no assumptions are taking how the mesh operates.
 

Basic Mesh Operation

• Four stream Rate vs Range, root only. Base performance of the root node
• Two stream Rate vs Range, all nodes. Base performance when using one hop

System Capacity

• Total mesh throughput
• Load the mesh with devices, measure maximum throughput and how that is distributed across the stations

AP Steering

• Optimal association Test
• Emulate ten locations in three real home(s), verify that device is steered to the optimal node in all cases

Band Testing

• Far-to-Near Band Steering
• Emulate STA approaching a mesh from far away and check that the mesh steers the STA to 5GHz when STA is closer

Roaming

• Roaming (with and without v)
  • Measures user experience during roaming for a client not supporting v
• Roaming under load (with and without v)
  • Measures user experience during roaming for a client not supporting v under load conditions
