ICMP RTT measurement from Taipei, Taiwan to Paris, France: average latency, packet loss, jitter and route efficiency for this Asia–Europe path.

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

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

In the 2026-08-16T04:07:28Z test round, ICMP echo requests from Taipei, Taiwan to Paris, France averaged 173.8 ms over 50 samples, with a minimum of 169.08 ms and a maximum of 187.89 ms. Zero packet loss and 3.31 ms jitter accompanied the fair latency tier.

Paris sits on the Northwest European corridor with dense national and pan-European fiber paths. The geodesic distance of about 9,846 km yields a vacuum floor of 65.69 ms and a fiber floor of 96.42 ms; the measured path runs about 1.8 times that fiber floor, or 55.5 percent fiber efficiency.

Against the 19 outbound routes in the same test set, this route ranks 14th, toward the slower side of the round. Its 3.91 ms standard deviation equals a relative spread of about 2.3 percent, below the median variability ratio of 3.28 percent across the same set, meaning the route is predictable even if its average latency is fair.

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: TPE → PAR

50 ICMP echo samples at 100 ms intervals · round 2026-08-16T04:07:28Z · avg 173.8 ± 0.55 ms (SE)

Sample distribution: box = interquartile range (171.4–175.0 ms), median 172.9 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 Taipei (25.05306, 121.52639) and Paris (48.85341, 2.34880). 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	1.8×

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.
