Web Browsing State Management for Bandwidth-Limited Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in delivering a satisfactory web browsing experience on bandwidth and capability-limited mobile devices, particularly in client-server environments, due to resource allocation and user session management issues, which affect the quality of service for multiple users.
Innovation Solution
A system comprising web browsing engines, state manager engines, command process engines, and provision manager engines that manage and provision user sessions, allowing remote interaction and resource allocation based on user profiles, to ensure efficient delivery of web browsing sessions across diverse devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If web browsing sessions are delivered to bandwidth-limited mobile devices, then user accessibility is improved, but resource allocation efficiency deteriorates
Solution Approach 1:
A server acts as an intermediary between the web content source and mobile devices, hosting multiple browser instances and managing session states. This intermediary approach allows bandwidth-limited devices to access web browsing without each device needing full browser functionality, improving accessibility while the server efficiently manages resources across multiple users.
Solution Approach 2:
The server hosts multiple browser instances that can serve multiple users simultaneously, with each browser instance capable of handling different user sessions. This multi-functionality allows a single server system to provide web browsing services to numerous bandwidth-limited devices, improving accessibility while consolidating resource usage.
2Adaptability or versatility
If multiple user sessions are supported on a server, then user experience is improved, but system complexity increases
Solution Approach 1:
The system segments user sessions into separate browser instances, with each instance maintaining its own state independently. This segmentation allows multiple users to be supported simultaneously while simplifying management, as each browser instance operates as a separate manageable unit with isolated state information.
Solution Approach 2:
Multiple browser instances are created as copies of a base browser template, each copy maintaining its own state. This copying approach allows the server to support multiple users with consistent functionality while managing complexity through standardized instance creation and state isolation.
3Reliability
If browsing state is maintained for each user, then user experience continuity is improved, but memory usage increases
Solution Approach 1:
The browsing state is extracted and maintained separately in the browser instance state rather than being embedded in the device. This extraction allows the server to maintain session continuity for each user while efficiently managing memory by storing state information centrally in the browser instances rather than duplicating it across multiple device representations.
