Client-Side Widget Message Bus for Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing client-server models for browsing computer-delivered content require multiple communication transactions between clients and servers, leading to increased latency and complexity, limiting the flexibility of widget communication and customization.
Innovation Solution
Implementing a message bus and registry within the client system that allows widgets to communicate directly without interacting with external servers, enabling peer-to-peer communication and reducing reliance on server-mediated interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If widgets communicate through external servers using the client-server model, then server-mediated interaction is maintained, but latency increases and communication complexity increases
Solution Approach 1:
The patent extracts the message bus functionality from the external server environment and places it directly in the client's execution environment. This allows widgets to communicate peer-to-peer without routing messages through external servers, eliminating network round-trips and reducing latency while maintaining reliable communication through the structured message bus protocol.
Solution Approach 2:
The patent introduces a new dimension of communication by implementing a message bus that operates within the client's execution environment rather than through the traditional network dimension. This creates a local communication layer that bypasses external server dependencies, reducing both latency and network complexity.
2Device complexity
If widgets communicate through external servers, then centralized control is maintained, but device complexity and communication overhead increase
Solution Approach 1:
The patent segments the communication architecture by dividing it into independent components: the message bus for message routing, the registry for widget discovery, and the execution environment for widget operation. This segmentation allows each component to function independently without requiring complex server-mediated coordination, reducing overall system complexity while maintaining controlled communication through standardized protocols.
3Adaptability or versatility
If widgets are configured to execute independently, then widget independence is maintained, but widget communication flexibility is limited
Solution Approach 1:
The patent implements a universal message bus that serves multiple functions: message routing between independent widgets, event notification, data sharing, and coordination. This single universal communication mechanism supports diverse widget interaction patterns without requiring separate communication channels for each widget pair, enhancing communication flexibility while maintaining widget independence and reducing architectural complexity.

AI summary
Method and system for client-side communication among widgets. In one embodiment, instructions may be processor-executable within a system to implement a web browser and a number of widgets configured to execute within an execution environment provided by the web browser. The web browser may be configured to obtain content from servers external to the system, and members of at least a subset of the widgets may be configured to communicate with one another without interacting with any of the external servers.
