Client-Server Document Parsing via Windowed Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In client-server models for managing network configuration files, large files require significant parsing time on the server and result in delayed responses, consuming substantial computational resources and network bandwidth.
Innovation Solution
Implementing a system that uses windowing, delayed synchronization, and difference-based responses to efficiently parse and edit large network configuration files, where only the visible lines are initially loaded and parsed, with the remainder processed in the background, and updates are sent as differences rather than full files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the server parses and returns the entire large configuration file, then the client receives complete data, but the parsing time and network bandwidth consumption increase significantly
Solution Approach 1:
The patent divides the large configuration file into multiple segments based on line ranges. Instead of parsing and transmitting the entire file, the server parses and returns only the specific line segments requested by the client. This segmentation approach maintains data completeness for the required portions while significantly reducing parsing time and network bandwidth consumption.
Solution Approach 2:
The patent extracts only the necessary portions of the configuration file that correspond to the visible window and user requests. The server identifies and returns specifically the line segments needed for the current display area, extracting minimal necessary data rather than transmitting the complete file, thereby reducing processing time and network usage.
2Loss of information
If the server parses and returns the entire large configuration file, then the client receives complete data, but the network bandwidth consumption increases significantly
Solution Approach 1:
The patent segments the configuration file into line range portions and transmits only the specific segments needed for the current visible window. This approach ensures the client receives complete data for the displayed area while minimizing network bandwidth consumption by avoiding transmission of unnecessary file portions.
Solution Approach 2:
The patent implements partial action by returning only the necessary line segments for the visible window rather than the complete file. The server parses and transmits exactly what is needed for current display requirements, using minimal network bandwidth while providing sufficient data completeness for the user's current view.
3Loss of time
If the server parses only the initial lines of the configuration file, then the response time is reduced, but the completeness of the parsed data is limited
Solution Approach 1:
The patent segments the configuration file into multiple line range portions. The server initially parses and returns only the first segment (initial lines) for immediate display, reducing response time. Subsequently, as the user scrolls or navigates, additional segments are parsed and returned on-demand, ensuring data completeness is achieved progressively without requiring complete initial parsing.
Solution Approach 2:
The patent performs preliminary parsing of only the initial lines that will be displayed in the visible window before the user requests them. This preliminary action provides immediate visual feedback to the user while the rest of the file remains unparsed until needed, balancing response time with eventual data completeness.
4Loss of energy
If the server sends updates as difference-based responses, then the network bandwidth consumption is reduced, but the complexity of processing updates increases
Solution Approach 1:
The patent extracts and transmits only the difference portions (changed lines) rather than complete updated files. When the configuration file changes, the server identifies the specific line segments that have been modified and sends only those differences to the client. This approach minimizes network bandwidth consumption while the added processing complexity is confined to the server's difference calculation, which operates on already-parsed segment data.
Data Source
AI summary
The system receives, from a client, a first request for a document which is parsed based on a syntax. The system parses and returns an initial number of lines of the document, thereby allowing the client to display the parsed initial number of lines in a visible window. Subsequent to successfully parsing a remainder of the lines, the system stores a fully-parsed version. Responsive to a scrolling action in the visible window, the system provides a relevant portion of an unparsed document associated with the first request. Responsive to detecting a termination of the scrolling action, the system receives a second request for parsed lines corresponding to a first set of lines. The system returns the corresponding parsed lines, thereby allowing the client to display the corresponding parsed lines in the visible window.
