Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional synchronous data retrieval methods are used, then security can be maintained through direct connection management, but system performance declines during peak usage due to blocking operations
Solution Approach 1:
The patent introduces a gateway server as an intermediary component between requestors and data centers. The gateway receives requests, generates correlation identifiers, and manages asynchronous communication through queues. This mediator architecture allows the system to handle peak loads efficiently while maintaining security through controlled access points, resolving the contradiction between productivity and reliability.
Solution Approach 2:
The system performs preliminary actions by pre-establishing communication channels and using correlation identifiers to pre-link requests with their corresponding responses. Requests are queued and processed in advance, allowing the system to prepare for peak usage periods without blocking operations, thereby improving both efficiency and performance stability.
2Speed
If direct data center access is implemented, then data retrieval speed improves, but security vulnerabilities increase exposing customer data to hackers
Solution Approach 1:
The gateway server serves as a security intermediary that all data requests must pass through. It validates requests, manages correlation identifiers, and controls access to data centers. This architecture maintains fast data retrieval through optimized communication paths while adding security layers that prevent direct unauthorized access, thus resolving the speed-security contradiction.
Solution Approach 2:
The system segments the data retrieval process into distinct phases: request submission to gateway, correlation identifier generation, asynchronous processing through queues, and response delivery. This segmentation allows security checks to be performed at specific checkpoints without blocking the overall data flow, maintaining speed while enhancing security.
3Productivity
If synchronous request-response processing is used, then request tracking is simplified, but system efficiency decreases during high traffic periods
Solution Approach 1:
The gateway server acts as an intermediary that manages the complexity of asynchronous communication. It generates and tracks correlation identifiers, queues requests and responses appropriately, and handles the matching of requests with responses. This centralizes the complexity management, allowing high throughput without requiring complex tracking logic at each endpoint.
Solution Approach 2:
The system implements feedback mechanisms through correlation identifiers that link requests with their corresponding responses. The gateway monitors the state of requests and responses in queues, and can implement timeout logic to provide feedback when responses are not received within expected timeframes. This feedback system maintains efficiency during high traffic by preventing resource exhaustion from orphaned requests.
Data Source
AI summary
A method for managing data requests is provided. Two asynchronous processes are provided for managing communication with a requestor and an agent via a gateway server. The method may include receiving a request and agent identifier from a requesting web application and generating a correlation identifier to associate with the request. The request and correlation identifier may be routed to a registered agent of a private data center. A response may be returned and routed to the requestor based on the correlation identifier. Corresponding apparatuses and computer program products are also provided.
