SW-595 RFC 2544 Test Report

This page presents the RFC 2544 benchmark test results for the Brainboxes SW-595 5-port Gigabit Ethernet switch with SFP. 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 13 May 2026, with a total test duration of 12 hours 27 minutes. Tests used custom frame sizes including IEEE defaults and jumbo frames (64, 128, 256, 512, 1024, 1280, 1518, 2048, 4096, 8192, and 9000 bytes) in a full-mesh, bidirectional topology across 5 ports at 1 Gbps (5 Gbps aggregate, 20 bidirectional flows).

Result: All Tests Passed

The SW-595 passed all RFC 2544 tests. It sustained full 4.98 Gbps aggregate line rate with zero frame loss across all 20 bidirectional flows for every IEEE-standard frame size (64–1518 bytes) and jumbo frame sizes up to 4096 bytes. Forwarding latency was exceptionally low at 1.6–43 µs at 50% load.

Test	Result
Throughput	Pass — 99.6% line rate, zero loss for all frame sizes 64–4096 bytes
Latency & Jitter	Pass — at 50% and 100% rates
Frame Loss Rate	Pass — 0% loss at 50% rate for 64–4096 bytes
Back-to-Back	Pass — at 50% and 100% rates

Jumbo frame note (8192 / 9000 bytes)

At 8192- and 9000-byte frames the Xena test instrument's traffic generator could only offer 25–35% of line rate; the switch forwarded those frames with zero loss at the achievable offered rate. Under 100% offered rate, elevated loss was observed at 8192 / 9000 bytes — this is expected behaviour when the aggregate jumbo-frame load exceeds the switch's internal forwarding budget. See the per-test sections below for full numbers.

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 0–100% line rate and 0% acceptable loss.

The SW-595 achieved 99.609% throughput (4.98 Gbps of the 5 Gbps aggregate line rate) with zero frame loss for all frame sizes from 64 through 4096 bytes. For 8192- and 9000-byte jumbo frames the Xena instrument's generator was limited to 27.2% and 25.4% of line rate respectively; the switch forwarded all offered frames with zero loss at those reduced rates.

All 20 bidirectional flows in the full mesh showed identical throughput with zero loss at every frame size.

Per-Port Throughput Results

All five ports produced identical throughput in the full-mesh topology. Each port transmits 1/5 of the aggregate traffic, and receives the same.

Ports P-0-2-1 through P-0-2-4 — identical results

Ports P-0-2-1, P-0-2-2, P-0-2-3, and P-0-2-4 each produced the same per-port frame counts, line rates, and zero loss as P-0-2-0 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 five per-port averages, with min/max latency taken from the worst case across all ports.

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.

At 50% rate the SW-595 achieved zero frame loss for all frame sizes from 64 through 4096 bytes. For 8192 and 9000 the offered rate exceeded what one path could sustain in the mesh, producing 6.33% and 19.54% loss respectively. At 100% rate small per-flow losses (0.01–0.1%) were observed for 64- through 4096-byte frames, and substantially higher loss for 8192/9000-byte jumbo frames.

Per-Port Frame Loss at 50% Rate

All five ports transmitted identical frame counts at 50% rate. Loss occurred only at 8192- and 9000-byte frame sizes, distributed across the mesh flows.

All other ports transmitted the same per-port frame counts. Receive counts at 8192 and 9000 bytes varied per flow; see the source PDF for per-flow detail.

Per-Port Frame Loss at 100% Rate

At 100% rate, each port offered 1 Gbps and received 1 Gbps in the full mesh. The very small losses observed at 64- through 4096-byte frame sizes (well under 0.1%) are characteristic of mesh saturation transients during port-sync. At 8192- and 9000-byte jumbo frames the mesh aggregate exceeds the switch's jumbo-frame forwarding budget, producing 30–34% loss.

Back-to-Back Test

Results at 100% Rate

At 100% rate (full 5 Gbps aggregate) the back-to-back burst sizes are smaller per frame size because the rate divisor is doubled, but every burst completed with zero frame loss.

About This Test

RFC 2544 defines a standardised benchmarking methodology for network interconnect devices. The tests cover:

• Throughput — maximum rate at which no frames are lost
• Latency — forwarding delay at various frame sizes and rates
• Frame Loss Rate — percentage of frames lost under load
• Back-to-Back — maximum burst length the device can handle without loss

Testing was performed using the Xena2544 automated test suite. Each test was run for 3 iterations and results averaged to minimise measurement variance. This report extends the standard IEEE frame sizes with jumbo frames (2048, 4096, 8192, and 9000 bytes) to validate jumbo frame support.
