ICMP round-trip time measurement from Paris, France to Taipei, Taiwan: 171.9 ms average latency, jitter, packet loss, and distance context.

🇫🇷 Paris, France (PAR) → 🇹🇼 Taipei, Taiwan (TPE)

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

During the 2026-08-16T04:07:28Z round, ICMP echo requests from Paris to Taipei returned an average round-trip time of 171.9 ms across 50 samples. The fastest reply was 163.74 ms, the slowest 192.89 ms, and with a standard deviation of 7.09 ms and jitter of 5.24 ms the path remained consistent with zero loss.

The observed RTT is 1.78 times the fiber-floor estimate of 96.42 ms for the 9,846.2 km great-circle distance, corresponding to a fiber efficiency of 56.1%. The excess over the floor represents cable routing and switching overhead, and the low jitter plus complete reply set suggest it is not driven by congestion.

On the Paris outbound set of 19 routes, Taipei ranks 14th and falls on the slower side of the group. The median standard-deviation-to-average ratio for those routes is 3.28%; at 4.12% of its own average, this route's variability is only slightly above that norm, making the measured 171.9 ms a stable result for the route.

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: PAR → TPE

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 171.9 ± 1.00 ms (SE)

Sample distribution: box = interquartile range (166.8–174.1 ms), median 169.1 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 (96.4 ms) for this route.

Theoretical Fiber Latency

The public physical reference uses the GeoNames city centres for Paris (48.85341, 2.34880) and Taipei (25.05306, 121.52639). It does not disclose either facility address.

Physical Reference	Value
WGS-84 geodesic distance	9,846.2 km
Vacuum RTT floor	65.69 ms
Standard fiber RTT floor ( $n_g=1.4679$ )	96.42 ms
Low-latency fiber material floor	96.03 ms
Engineering floor (5% path allowance)	101.26 ms
Research 1.33× mapped-fiber reference	128.24 ms
Estimated unamplified path loss	2067.7 dB
Transparent optical spans / inline amplifiers	130 / 129
Published RTT inflation over fiber floor	1.78×

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.
