ICMP echo RTT measurements from Marseille, France to Frankfurt, Germany: 50 probes, average latency, jitter, packet loss, and fiber efficiency for this route.

🇫🇷 Marseille, France (MRS) → 🇩🇪 Frankfurt, Germany (FRA)

Measurement round: 2026-08-15T04:03:13Z.

For the 2026-08-15T04:03:13Z round, ICMP echo probes from Marseille, France to Frankfurt, Germany produced an average RTT of 17.5 ms across 50 samples, with a minimum of 16.8 ms and a maximum of 19.59 ms. Packet loss was 0 percent, while jitter measured 0.56 ms and standard deviation 0.65 ms, placing the route in the Ultra-Low latency tier.

Against a geodesic distance of 798.8 km, the theoretical vacuum floor is 5.33 ms and the straight-fiber floor is 7.82 ms. The observed 17.5 ms average is 2.24 times that fiber floor, corresponding to a fiber efficiency of 44.7 percent, and Frankfurt's role as the central switching point of the European fiber ring helps explain the additional path distance.

This route ranked second among the 19 routes measured from Marseille in this round, while the median variation for the measured network was 3.08 percent of average latency. The route's absolute delay spread is tight, with a 0.65 ms standard deviation and 0.56 ms jitter, giving operators a stable and repeatable Marseille-to-Frankfurt latency reference.

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: MRS → FRA

50 ICMP echo samples at 100 ms intervals · round 2026-08-15T04:03:13Z · avg 17.5 ± 0.09 ms (SE)

Sample distribution: box = interquartile range (17.1–17.7 ms), median 17.3 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 (7.8 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Marseille (43.29695, 5.38107) and Frankfurt am Main (50.11552, 8.68417). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	798.8 km
Vacuum RTT floor	5.33 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	7.82 ms
Low-latency fiber material floor	7.79 ms
Engineering floor (5% path allowance)	8.21 ms
Research 1.33× mapped-fiber reference	10.4 ms
Estimated unamplified path loss	167.7 dB
Transparent optical spans / inline amplifiers	11 / 10
Published RTT inflation over fiber floor	2.24×

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.
