Looking Glass FAQs

Question 1

What network diagnostic commands does Looking Glass support?

Accepted Answer

It supports comprehensive commands essential for network analysis, including `ping` for latency and reachability, `BGP` (Border Gateway Protocol) route lookups for routing intelligence, and `traceroute` for path analysis. All commands can be executed from various global locations.

Question 2

What is Looking Glass and its primary purpose?

Accepted Answer

Looking Glass (specifically, Looking-Glass-MCP) is a powerful network probing and diagnostic tool that leverages multiple global vantage points to offer extensive insights into network performance, routing, and connectivity worldwide. It's built for efficient, concurrent operations.

Question 3

How does Looking Glass help with CDN performance optimization?

Accepted Answer

By allowing you to run tests like ping and traceroute from diverse global vantage points, Looking Glass helps identify latency, packet loss, and routing inefficiencies specific to different regions. This enables data-driven CDN strategy, competitive analysis, and optimization for improved user experience.

Question 4

What are the main real-world applications for Looking Glass?

Accepted Answer

Looking Glass is ideal for CDN performance optimization, deep network troubleshooting, DDoS detection, competitive infrastructure benchmarking, global SLA monitoring, and academic research on internet topology and performance.

Question 5

Can I choose which vantage points to use for my tests?

Accepted Answer

Yes, Looking Glass offers flexibility. You can either manually specify a list of desired Looking Glass VP (Vantage Point) identifiers or let the tool automatically select an optimal number of vantage points for your measurements, providing precise or automated control over your tests.
