Client Notification Queue for Stateless State Machine Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer networking environments, maintaining an accurate representation of a state machine on both client and server devices is computationally complex and bandwidth-intensive, especially when using stateless communication protocols.
Innovation Solution
Implementing an electronic notification queue on the client device to manage state transitions, where notifications are stored and delivered in a first-in-first-out order, allowing users to interact with the state machine through visual cues like popup windows, and removing notifications based on user input or timer conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional state machine maintenance methods are used on both client and server, then accurate state representation is achieved, but bandwidth usage and computational complexity increase
Solution Approach 1:
The patent extracts the state machine maintenance function from the server and relocates it to the client device. The server sends only state transition notifications instead of maintaining the complete state machine, thereby reducing server computational complexity while the client handles state tracking locally.
Solution Approach 2:
The patent introduces a notification queue as an intermediary mechanism between server and client. The queue manages state transition notifications locally on the client, eliminating the need for continuous server-client communication to maintain state accuracy, thus reducing bandwidth usage while preserving state representation reliability.
2Reliability
If complete state information is transmitted between server and client, then state synchronization is maintained, but bandwidth usage increases
Solution Approach 1:
The patent extracts only the essential state transition notifications from the complete state information and transmits them to the client. The notification queue processes these minimal notifications locally, achieving state synchronization without transmitting redundant state data, thereby significantly reducing bandwidth consumption.
Solution Approach 2:
The client device is empowered to maintain its own state machine representation by processing incoming notifications autonomously through the notification queue. This self-service approach eliminates the need for the server to continuously transmit and synchronize complete state information, reducing bandwidth usage while maintaining synchronization reliability.

AI summary
Systems and methods of implementing a finite-state machine using electronic notifications delivered to a client device in a computer networking environment are provided. A content item can be received, along with first and second notifications associated with the content item. The first and second notifications can be stored in a queue. In some implementations, a state machine can be maintained in which at least some states may cause the first or second notifications to be displayed, and in which transitional conditions between states may depend at least in part on user interaction with the displayed notifications.
