Proxy Address Neutrality for Mobile Server Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed computing environments, especially with mobile devices, the frequent change in network addresses renders existing proxy systems error-prone and burdensome for developers to update, as they require manual recreation or updating of proxies to maintain connectivity.
Innovation Solution
A system where a server application registers its network address with a discovery application, allowing client applications to retrieve and use updated addresses automatically, ensuring proxy address neutrality and reducing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual proxy updating is used, then developers can maintain control over proxy updates, but the process becomes error-prone and burdensome
Solution Approach 1:
The system enables automatic proxy address updates through the client application autonomously querying the discovery application and retrieving new addresses without developer intervention. This self-service mechanism eliminates manual proxy recreation while ensuring reliability through automated address validation and updates.
Solution Approach 2:
The discovery application provides feedback mechanisms by storing and providing current server addresses to client applications. This feedback loop ensures that clients always have access to valid addresses, improving reliability while reducing manual operational burden through automated information flow.
2Reliability
If proxies are recreated when address changes, then connectivity is maintained, but developer burden increases significantly
Solution Approach 1:
The discovery application serves as an intermediary between the server and client applications. It stores server address information and provides it to clients automatically, eliminating the need for developers to manually recreate proxies while maintaining connectivity reliability through automated address resolution.
Solution Approach 2:
The system performs preliminary actions by having the client application automatically query the discovery application for current addresses before attempting proxy communication. This preliminary address verification ensures connectivity reliability while reducing complexity by preventing failed connection attempts that would require manual intervention.
3Adaptability or versatility
If automatic address updates are implemented, then proxy neutrality is achieved, but system complexity increases
Solution Approach 1:
The discovery application performs multiple functions: storing server address information, providing address queries to clients, and enabling automatic updates. This multi-functional approach achieves address change adaptability while containing system complexity by consolidating discovery operations into a single versatile component that can be implemented within existing application frameworks.

AI summary
To provide proxy address neutrality, in particular for mobile server devices, a server application can register its network address with a discovery application. Whenever the server application acquires a new network address, the server application updates the discovery application. A client application providing proxy services for the server application can invoke calls to the server client using the network address for the server application that is currently stored in the client device. If the current network address is invalid, the client application obtains an updated network address from the discovery application.
