Intermediary Rate Throttler for Server Request Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In enterprise networks, managing access to various objects to prevent resource overload and ensure priority delivery of critical objects is challenging due to varying object sizes and user requests, which can impact business operations and lead to potential revenue loss if not managed effectively.
Innovation Solution
Implementing a system and method for rate limiting that allows administrators to specify a maximum load threshold for resources, using an intermediary to throttle requests based on user-defined criteria, such as bursty or smooth modes, to prevent resource overload by controlling the number of requests or bandwidth within a specified time frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are allowed unrestricted access to request any object from servers, then user freedom and access flexibility are improved, but network resource overload and server performance degradation occur
Solution Approach 1:
The patent introduces a rate limiter as an intermediary component between clients and servers that mediates request flow. The rate limiter monitors request rates, compares them against configured thresholds, and selectively allows or blocks requests based on current load conditions, thus protecting servers from overload while maintaining user access flexibility within safe limits.
Solution Approach 2:
The system implements feedback mechanisms where the rate limiter continuously monitors network traffic patterns, server response times, and resource utilization metrics. Based on this feedback, the rate limiter dynamically adjusts its throttling behavior to maintain optimal network performance and prevent resource exhaustion while allowing legitimate user access.
2Reliability
If rate limiting is applied to all object requests uniformly, then resource protection is improved, but differentiated service quality for priority objects deteriorates
Solution Approach 1:
The patent implements local quality by applying different rate limiting policies to different object types, users, or time periods. The system can configure specific thresholds and rules for critical business objects versus non-critical objects, ensuring that resource protection measures are tailored to the specific characteristics and importance of each object category rather than applying a one-size-fits-all approach.
3Stability of the object's composition
If strict rate thresholds are enforced to prevent resource overload, then system stability is improved, but legitimate user requests may be blocked causing productivity loss
Solution Approach 1:
The rate limiting system employs dynamic threshold adjustment based on real-time network conditions, server capacity, and historical traffic patterns. Rather than using fixed static thresholds that may incorrectly block legitimate traffic, the system adapts its rate limits dynamically to distinguish between malicious overload and legitimate high-volume requests, maintaining system stability while minimizing false positives that would harm productivity.

AI summary
The present application is generally directed to systems and method for throttling a rate of requests between a client (102) and a server (106) using user specified inputs. A rate of requests for an object may be throttled by an intermediary (200) which receives requests transmitted between a client (102) and a server (106) and via the intermediary (200). The intermediary (200) may receive a request from a client (102) for an object of a server (106). The intermediary (200) may identify a policy (420) specifying a mode of throttling for the request, the policy (420) specifying a mode of throttling, a rate threshold and a period of time for the rate threshold. The rate throttler (405) of the intermediary (200) may determine whether the request exceeds the rate threshold for the period of time based on the mode of throttling of the policy (420) and allow or block the request responsive to the determination.
