Access Interface Traffic Limiting for High-Concurrency User Requests

The patent segments traffic limiting into two distinct approaches: (1) interface-level traffic limiting that applies to all requests when total concurrency exceeds a threshold, and (2) user-level rate limiting that tracks individual user request frequencies. This segmentation allows the system to apply different limiting strategies to different scenarios, ensuring system stability while preserving user access success rates by allowing urgent or legitimate requests to pass through.

The patent implements local quality by applying traffic limiting selectively rather than uniformly. The system monitors the frequency of requests from individual users and applies rate limiting only to users whose request frequency exceeds their personal threshold, while other users' requests are processed normally. This localized approach ensures that system stability is maintained for problematic users without negatively impacting the access success rate for legitimate users.

The patent implements self-service by allowing the system to automatically monitor and regulate its own traffic patterns without external intervention. The traffic limiting component continuously tracks request frequencies, identifies users exceeding thresholds, and applies rate limiting autonomously. This self-service mechanism prevents system overload while minimizing impact on user experience, as legitimate users whose requests fall within normal patterns are not subjected to limiting.

The patent utilizes parameter changes by dynamically adjusting traffic limiting based on monitored request frequencies. The system observes the rate of incoming requests from each user and adjusts whether to apply limiting on a per-request basis. This dynamic parameter adjustment allows the system to prevent overload conditions while maintaining good user experience for legitimate traffic patterns.
