Server Resource Throttling via Latency-Based Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In modern server systems, resource contention leads to inefficiencies and vulnerabilities, such as denial-of-service attacks where malicious entities can monopolize resources, preventing legitimate clients from accessing them timely.
Innovation Solution
A computing device acts as a server that throttles resource access by calculating a delay period based on a client's recent latency level, delaying secondary requests to prevent monopolization and allow other clients to access resources efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a client sends a large number of requests to access a resource, then the client can quickly access the resource when needed, but the client may monopolize the resource and prevent other clients from accessing it
Solution Approach 1:
The patent implements periodic action by introducing delay periods between requests from the same client. The delay period is calculated based on the client's recent latency level, creating a rhythmic pattern of request throttling that prevents monopolization while allowing legitimate access. This periodic interruption ensures resource availability for other clients while maintaining service for the original client.
2Productivity
If the server processes all requests immediately, then system throughput is maximized, but malicious entities can launch denial of service attacks by sending大量 illegitimate requests
Solution Approach 1:
The patent introduces an intermediary mechanism (the first server acting as a gateway) that mediates between clients and the resource. This intermediary calculates delay periods and throttles requests before they reach the resource, filtering out potential denial of service attacks while allowing legitimate requests to pass through. The intermediary protects the resource without completely blocking productivity.
3Reliability
If delay periods are imposed on all clients, then resource monopolization is prevented, but legitimate clients experience excessive delays
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the delay period duration based on the client's recent latency level. Clients with normal latency experience shorter or no delays, while clients showing monopolization behavior experience longer delays. This adaptive parameter adjustment maintains resource fairness without imposing excessive delays on legitimate clients.
Data Source
AI summary
A computing device provides a first server. The first server receives a primary request associated with a client. In response to receiving the primary request, the first server processes the primary request to generate a response message. As part of processing the primary request, the first server sends a secondary request to a second server after a delay period expires. The second server accesses a resource as part of processing of the secondary request. The duration of the delay period depends at least in part on a recent latency level of the client with regard to the resource. In this way, the first server throttles access to the resource.
