Looking Glass

Looking Glass is Zenlayer’s online network probing and visualization tool, designed for global users to evaluate real-time network path quality, latency, ISP performance, and acceleration effectiveness. It covers Zenlayer’s global PoP (Point of Presence) nodes and supports multiple protocols (e.g., Ping, MTR, BGP) for both private and public network analysis.

Looking Glass is composed of several specialized modules, each designed to analyze different aspects of global network performance:

• Route Explorer: Diagnose routing paths and network link quality from Zenlayer PoPs to target IPs or domains using Ping, MTR, and BGP.

• Last-mile Performance: Gain insights into the quality of last-mile connectivity by exploring each PoP's coverage of local ISPs (eyeball networks) and their corresponding average ping latency (ms). Ideal for evaluating regional network performance and user experience.

• Private Backbone Latency: Visualize real-time latency across Zenlayer’s premium global private backbone with full-mesh connectivity. This module supports planning and optimization of Private Connect (Layer 2) and Cloud Router (Layer 3) deployments by providing accurate latency measurements between PoPs.

• Public Transit Latency: Analyze real-time latency across Zenlayer’s 150+ Tbps global IP transit network. This module reveals routing performance between public-facing PoPs, helping benchmark public internet routes against private backbone alternatives.

• Global Acceleration Test: Simulate real-world download scenarios by measuring the time to fetch a 1 MB test file from your selected source region. Use this module to assess the impact of Zenlayer acceleration on cross-border content delivery and user experience.

Together, these modules provide a comprehensive view of global network health — from core backbone routing to end-user last-mile performance — helping users monitor, troubleshoot, and optimize their network experience across Zenlayer’s global infrastructure.
