ISP Throttling Detector for Gamers: Pinpoint network issues.
The user describes a highly reproducible and frustrating network issue: internet speed collapses only when a specific game (League of Legends) is launched. They suspect ISP traffic shaping, peering issues, or modem-level misclassification of game traffic (specifically UDP). The key pain point is the lack of tools to definitively diagnose and prove these ISP-level or modem-specific throttling behaviors. While general network tools exist, they often don't provide application-specific insights or actionable evidence for ISP support. A SaaS product could fill this niche by offering a specialized diagnostic tool that:
- Monitors Application-Specific Network Performance: Tracks bandwidth, latency, packet loss, and jitter when specific games/applications are active, comparing it to a baseline.
- Analyzes Protocol & Port Usage: Identifies if specific protocols (like UDP, which LoL uses) or port ranges are being disproportionately affected.
- Detects Traffic Shaping/DPI: Employs advanced techniques to detect patterns consistent with deep packet inspection or traffic shaping applied by the ISP or modem.
- Generates Actionable Reports: Provides clear, data-driven reports with graphs and evidence that users can present to their ISP support to substantiate their claims.
- Community-Driven Insights: Aggregates anonymized data from users to identify common problems across specific ISPs, games, or regions, giving users more leverage.
This would empower gamers to identify and resolve performance bottlenecks that are currently very difficult to prove, offering significant value to a passionate and often frustrated user base. The problem described in the post is a clear example of such a need.
