ICMP echo RTT measurement from Melbourne, Australia to Frankfurt, Germany: round-trip time, packet loss, jitter, and route efficiency for a 16,315 km path.

🇦🇺 Melbourne, Australia (MEL) → 🇩🇪 Frankfurt, Germany (FRA)

Measurement round: 2026-08-16T04:07:28Z.

For the 2026-08-16T04:07:28Z round, ICMP echo RTT from Melbourne to Frankfurt averaged 248.6 ms over 50 samples, with a minimum of 238.22 ms, a maximum of 288.5 ms, and zero packet loss.

That average is 1.56 times the theoretical fiber floor for the 16,315.5 km geodesic separation, giving a fiber efficiency of 64.3 percent. With 10.01 ms standard deviation and 8.5 ms jitter, the connection held a fairly steady latency profile despite being a long intercontinental route.

In the context of the 19 outbound routes in this network's monitoring set, the Melbourne-Frankfurt average ranks 14th by RTT. The network's median stdev-to-average ratio sits at 3.28 percent, while this route's standard deviation is about 4.03 percent of its average, so it is slightly more variable than the midpoint rather than dramatically inconsistent.

The minimum sample of 238.22 ms is just 49 percent above the direct-fiber minimum, showing the path can get close to the physical bottom under good conditions. ICMP RTT reflects reachability and delay, not the full experience an end user would see, and it should not be treated as an SLA or a proxy for application performance.

Ping Measurement Series

The chart below renders the 50-sample ICMP echo measurement round for this route; an accessible table of every sample is included with the chart.

Ping series: MEL → FRA

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 248.6 ± 1.42 ms (SE)

Sample distribution: box = interquartile range (242.0–251.2 ms), median 246.5 ms · whiskers = min–max · diamond = round average · each dot is one measured sample.

How to read this chart

The shaded band spans the measured minimum to maximum RTT of all samples collected up to that point, and the thin line traces the running average. The final position therefore matches the round statistics exactly — the band only widens when a new extreme sample arrives.

The dashed line is the round average, and the shaded band at the bottom is the theoretical fiber-optic floor (159.8 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Melbourne (-37.81400, 144.96332) and Frankfurt am Main (50.11552, 8.68417). It does not disclose either facility address.

Vacuum RTT floor	108.85 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	159.77 ms
Low-latency fiber material floor	159.13 ms
Engineering floor (5% path allowance)	167.78 ms
Research 1.33× mapped-fiber reference	212.5 ms
Estimated unamplified path loss	3426.2 dB
Transparent optical spans / inline amplifiers	215 / 214
Published RTT inflation over fiber floor	1.56×

Attenuation is used to estimate the number of 80 km optical spans; it does not directly slow light. See the full theoretical fiber latency, GeoNames, attenuation, and amplifier methodology.

About This Measurement

Published RTT reflects best-case backbone path behavior measured with ICMP echo probes between PoPs. End-user latency also depends on local access networks, congestion, routing policy, and traffic engineering. None of these values is an SLA.
