Multi-process Browser Architecture Fault Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional browsers operate with a single process architecture, where a fault in one tab can cause unexpected termination of the entire browser process, affecting user experience and efficiency, as all content areas share the same rendering engine and process.
Innovation Solution
Implementing a multi-process browser architecture where each content area has a unique rendering process and browser process, allowing inter-process communication to isolate faults and prevent them from affecting other processes, using methods like named pipes for communication and watchdog threads to manage faulty processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rendering engine is used to render multiple content areas in a tab view browser, then device complexity is reduced, but reliability deteriorates because a fault in the rendering engine affects all content areas
Solution Approach 1:
The patent divides the browser architecture into multiple independent processes: a browser process and one or more rendering process groups. Each rendering process group contains one or more rendering processes that can be independently managed. This segmentation isolates faults to specific rendering processes rather than affecting the entire browser, thereby improving reliability while maintaining manageable complexity through structured organization.
2Ease of operation
If all content areas share the same browser process, then ease of operation is improved, but reliability worsens because a fault in one tab can cause unexpected termination of the entire browser process
Solution Approach 1:
The patent segments the browser into a browser process that handles user interface and coordination, and separate rendering process groups that handle actual content rendering. This allows the browser process to remain responsive and operational even when individual rendering processes fail, improving reliability while maintaining ease of operation through centralized browser process coordination.
Solution Approach 2:
The patent introduces intermediary components including a render view host in the browser process that communicates with rendering processes through standardized interfaces. This intermediary layer allows the browser process to manage multiple rendering processes independently, isolating faults while maintaining coordinated operation and ease of use.
3Manufacturing precision
If a single rendering engine renders multiple content areas, then manufacturing precision is improved in terms of consistent rendering, but reliability deteriorates because the rendering engine may become unresponsive affecting all content areas
Solution Approach 1:
The patent divides rendering functionality into separate rendering processes grouped in rendering process groups, each capable of independent operation. This segmentation allows consistent rendering standards to be maintained across all processes while isolating responsiveness issues to individual processes rather than affecting the entire rendering system.
Solution Approach 2:
The patent enables dynamic parameter changes in rendering processes, allowing the browser to adjust rendering priorities, resource allocation, and process activation based on system conditions. This flexibility maintains rendering consistency while improving reliability by allowing individual processes to be restarted or reconfigured without affecting others.

AI summary
Systems and methods for multi-process browser architecture are described herein. In an embodiment, a system for providing multi-process browser architecture includes at least one rendering process for each browser instance that renders a content area; and at least one browser process that communicates with one or a plurality of rendering engine processes. In another embodiment, a method for providing a multi-process browser architecture includes instantiating a unique rendering process for each content area instance and instantiating a unique browser process. In this way browsers may avoid the effects of faulty processes affecting other browser processes. This may improve user efficiency while enhancing user experience.
