SW-7016 RFC 2544 Test Report
This page presents the RFC 2544 benchmark test results for the Brainboxes SW-7016 16-port hardened industrial Fast Ethernet switch. RFC 2544 defines a standardised methodology for benchmarking network interconnect devices, covering throughput, latency, frame loss rate, and back-to-back frame handling.
Testing was performed using the Xena2544 v2.97 automated test suite on 24 April 2026, with a total test duration of 3 hours 8 minutes. Tests used the IEEE default frame sizes (64, 128, 256, 512, 1024, 1280, and 1518 bytes) in a full-mesh, bidirectional topology across all 16 ports at 100 Mbps (1.6 Gbps aggregate, 240 bidirectional flows).
The SW-7016 passed all RFC 2544 tests, sustaining full 1.6 Gbps aggregate line rate with zero frame loss across all 240 bidirectional flows for every IEEE-standard frame size from 64 to 1518 bytes, at both 50% and 100% offered load.
| Test | Result |
|---|---|
| Throughput | Pass — 100% line rate at all frame sizes, zero loss |
| Latency & Jitter | Pass — at 50% and 100% rates |
| Frame Loss Rate | Pass — 0% loss at both 50% and 100% rates |
| Back-to-Back | Pass — at 50% and 100% rates |

Port Configuration
All 16 ports are SFP-E 10/100/1000M interfaces auto-negotiated to 100 Mbps:
| Port ID | Interface Type | Speed | Rate |
|---|---|---|---|
| P-0-0-0 to P-0-0-5 | SFP-E 10/100/1000M | Auto | 100 Mbps |
| P-0-2-0 to P-0-2-3 | SFP-E 10/100/1000M | Auto | 100 Mbps |
| P-0-4-0 to P-0-4-5 | SFP-E 10/100/1000M | Auto | 100 Mbps |
Throughput Test
The throughput test determines the maximum rate at which none of the offered frames are dropped by the device. Each frame size was tested for 60 seconds over 3 iterations, with a binary search from 95–100% line rate at 0.5% resolution and 0% acceptable loss.
The SW-7016 achieved 100% throughput (1.6 Gbps aggregate line rate) with zero frame loss for every frame size from 64 through 1518 bytes.
| Frame Size (bytes) | Offered Rate | Tx Rate (L1) | Tx Rate (L2) | Tx (Frames) | Rx (Frames) | Loss | Result |
|---|---|---|---|---|---|---|---|
| 64 | 100% | 1.600 Gbps | 1.219 Gbps | 142,848,000 | 142,848,000 | 0 | Pass |

| 1024 | 100% | 1.600 Gbps | 1.569 Gbps | 11,491,200 | 11,491,200 | 0 | Pass |
| 1280 | 100% | 1.600 Gbps | 1.575 Gbps | 9,230,400 | 9,230,400 | 0 | Pass |
| 1518 | 100% | 1.598 Gbps | 1.577 Gbps | 7,790,400 | 7,790,400 | 0 | Pass |
All 240 bidirectional flows in the full mesh showed identical throughput with zero loss at every frame size.
Per-Port Throughput Results
All 16 ports produced effectively identical throughput in the full-mesh topology. Each port transmits 1/16 of the aggregate traffic and receives the same.
Port P-0-0-0 (representative — all 16 ports identical)
| Frame Size (bytes) | Tx (Frames) | Tx Rate (L1) | Tx Rate (L2) | Tx Rate (fps) | Rx (Frames) |
|---|---|---|---|---|---|
| 64 | 8,928,000 | 99.99 Mbps | 76.19 Mbps | 148,800 | 8,928,000 |
| 128 | 5,067,000 | 99.99 Mbps | 86.48 Mbps | 84,450 | 5,067,000 |
| 256 | 2,717,100 | 99.99 Mbps | 92.74 Mbps | 45,285 | 2,717,100 |
| 512 | 1,409,400 | 99.97 Mbps | 96.22 Mbps | 23,490 | 1,409,400 |
| 1024 | 718,200 | 99.97 Mbps | 98.06 Mbps | 11,970 | 718,200 |
| 1280 | 576,900 | 100 Mbps | 98.46 Mbps | 9,615 | 576,900 |
| 1518 | 486,900 | 99.85 Mbps | 98.55 Mbps | 8,115 | 486,900 |
Remaining 15 ports — identical results
Ports P-0-0-1 through P-0-0-5, P-0-2-0 through P-0-2-3, and P-0-4-0 through P-0-4-5 each produced the same per-port frame counts, line rates, and zero loss as P-0-0-0 above.
Latency and Jitter Test
The latency and jitter test measures forwarding delay and its variation across frame sizes. Tests were run for 60 seconds over 3 iterations using last-to-last latency mode, relative to the throughput test results. Testing was performed at both 50% and 100% of line rate.
Summary tables below show the mean of the 16 per-port averages, with min/max latency taken from the worst case across all ports. Average latency rises with frame size and with offered load because store-and-forward forwarding queues frames behind 15 other concurrent ingress streams per port at full mesh load.

Frame Loss Rate Test
The frame loss rate test measures the percentage of frames that are not forwarded by the device under steady-state conditions. Each frame size was tested for 60 seconds over 3 iterations. No pass/fail criteria were configured.
The SW-7016 achieved zero frame loss at both 50% and 100% offered rates, for every frame size from 64 through 1518 bytes.

Back-to-Back Test
The back-to-back test measures the longest burst of frames the device can forward without loss. Each frame size was tested for 60 seconds over 3 iterations with a common result scope. The SW-7016 sustained the full 60-second burst at both 50% and 100% offered rates for every frame size.

About This Test
RFC 2544 defines a benchmarking methodology for network interconnect devices, covering throughput, latency, frame loss rate, and back-to-back frame handling. Testing was carried out using the Xena2544 automated test suite (v2.97). Each measurement is the average of 3 iterations as specified in the test setup.
