Last-mile Performance
Overview
IP Network Last-Mile Performance shows the network quality between each PoP node and its end users in the corresponding service region. It includes data on ISP types, coverage, and average Ping latency. It usually has the following common use cases:
Common Use Cases
Site planning & PoP selection
Evaluate ISP quality in the target city or region
Coverage analysis
Compare end-user experience across multiple PoPs
Origin path optimization
Choose the ISP path with the lowest return latency
Performance auditing
Monitor Ping jitter and latency trends for a specific ISP
Procedures
Parameter Explanation
PoP Node
The source PoP for testing ISP connectivity. Test results vary by PoP. Only ISPs peered with Zenlayer are displayed.
Eyeball Location
The actual city/region where the end users are located, helping assess regional connectivity.
ISP Provider
The network provider serving the eyeball location.
Average Ping
The average latency from the PoP to the ISP, in milliseconds (ms). Lower and more stable values indicate better performance.
Select a PoP node, for example, Atlanta. You will see the accessible eyeball ISPs from that PoP, along with the following information:
Number of covered ISPs
Each ISP’s name and region
Average latency (ms)
You can sort by latency to identify the top-performing ISPs.
FAQ
Q1: How to identify the best ISP? A1: Look for the lowest average Ping and smallest jitter (standard deviation). Top 3 ISPs are usually optimal.
Q2: Does a small number of ISPs mean poor service? A2: Not necessarily. Some regions may rely on a few major ISPs with strong performance. Evaluate both coverage and quality.
Q3: Is packet loss shown? A3: Currently, only average Ping values are available.
Q4: Can ISP performance data be exported? A4: Data export is not supported at this time.
