Publish-Subscribe Messaging via Virtual Entities for Direct Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing publish-subscribe (pub-sub) messaging systems are inefficient in directly transmitting messages to specific computing devices, leading to scalability issues and message processing delays due to unnecessary iterations through non-subscribed devices, and lack of real-time tracking of connected devices.
Innovation Solution
A messaging system that allows direct communication between computing devices by using virtual entities to establish network connections, enabling direct message transmission to subscribed devices and reducing unnecessary message forwarding, while maintaining a pub-sub system architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional pub-sub messaging system is used, then message broadcasting to multiple devices is achieved, but message processing efficiency deteriorates due to unnecessary iterations through non-subscribed devices
Solution Approach 1:
The system performs preliminary actions by pre-establishing direct communication channels between publishers and subscribed devices before message transmission. Device connection systems proactively set up virtual entities and network connections, so when messages need to be delivered, the path is already prepared and ready for immediate use, eliminating the need to iterate through all devices during message processing.
Solution Approach 2:
The patent introduces device connection systems as intermediary components between publishers and subscribers. These intermediaries manage virtual entities and network connections, acting as mediators that handle the actual message routing. This separates the messaging logic from the connection management, allowing efficient direct transmission without requiring the pub-sub system to iterate through all registered devices.
2Adaptability or versatility
If a pub-sub system architecture is maintained, then system scalability is supported, but direct communication capability deteriorates due to lack of tracking for connected devices
Solution Approach 1:
The patent segments the messaging system into distinct functional components: pub-sub messaging layer for topic-based broadcasting, device connection systems for managing connections, and virtual entities for representing devices. This segmentation allows each component to specialize in its function, maintaining pub-sub scalability while adding direct communication capability through the separate connection management layer without increasing overall system complexity.
Solution Approach 2:
The device connection systems and virtual entities serve multiple functions: they manage network connections, track device states, enable direct communication, and support pub-sub messaging. This multi-functionality allows the system to provide both direct communication and maintain pub-sub architecture without adding separate dedicated components for each function, thereby avoiding increased complexity.
3Reliability
If all devices are iterated through during message transmission, then complete device coverage is achieved, but redundant processing increases due to non-subscribed devices
Solution Approach 1:
The system implements feedback mechanisms where device connection systems continuously track which devices are connected and subscribed to specific topics. This feedback information is used to optimize message routing, allowing the system to know exactly which devices should receive messages and which should not, eliminating redundant processing while maintaining reliable device coverage for subscribed devices.
