API Gateway Throttling for Real-Time Traffic Surge Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to manage traffic surges at servers, particularly for Application Programming Interfaces (APIs), leading to disruptions and inefficiencies, and there is a need for real-time control to prevent unauthorized requests and enhance server uptime and reliability.
Innovation Solution
A system and method using an API gateway with a load counter module, throttling parameter module, and authentication module to dynamically validate, throttle, and authenticate requests, setting capacity limits and preventing unauthorized access to manage traffic surges in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the server capacity is increased to handle more client requests, then the ability to manage traffic surge is improved, but the cost and complexity of the system increases
Solution Approach 1:
An API gateway is introduced as an intermediary component between client applications and the server. The gateway manages traffic surge by validating, throttling, and authenticating requests before they reach the server, allowing the server to maintain its capacity without requiring proportional increases in overall system complexity.
2Reliability
If the API gateway validates all requests in real-time, then the server reliability is improved, but the processing time and system complexity increase
Solution Approach 1:
The API gateway performs preliminary validation, authentication, and throttling checks on incoming requests before they are forwarded to the server. This preliminary action ensures that only valid requests reach the server, improving reliability while keeping the validation process efficient and manageable.
3Stability of the object's composition
If the API gateway throttles requests during traffic surge, then the server stability is improved, but the response time for legitimate requests may increase
Solution Approach 1:
The API gateway applies throttling selectively to requests that exceed predefined rate limits or capacity thresholds. Legitimate requests within acceptable parameters are processed without delay, while only the excessive portion of traffic is throttled to maintain server stability.
4Productivity
If the system implements real-time traffic control, then the server capacity optimization is improved, but the device complexity and processing overhead increase
Solution Approach 1:
The API gateway implements real-time monitoring of server capacity and request patterns, using this feedback to dynamically adjust throttling decisions. This feedback mechanism allows the system to optimize capacity utilization automatically without requiring complex manual control mechanisms.

AI summary
The present invention relates to systems and methods for controlling real-time traffic surge at a server [102]. An Application Programming Interface (API) gateway [104] receives at least one service request from at least one application device [106] for availing at least one service from a server [102], and enables at least one part of the server [102] based on a count of the received requests determined by a load counter. A throttling parameter, including one of a static throttling parameter and a dynamic throttling parameter, is determined by a throttling parameter module [204] for the enabled at least one part of the server [102]. The API gateway [104] validates the at least one service request based on the count and the throttling parameter. Thereafter, the at least one part of the server [102] provides at least one service to the validated at least one application device [106].
