OT Proxy for Collaborative Editing Reducing Server Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional collaborative editing systems using a server-client model can be resource-intensive and lead to scalability issues, particularly when supporting thin clients with limited hardware resources, as they require server-side operational transformation, which may not be feasible for all client devices.
Innovation Solution
Implementing an operational transformation proxy (OT proxy) that acts as an intermediate component between the server and thin clients, allowing for local operational transformation of updates on smart clients and ensuring convergence of client and server versions of electronic documents, thereby reducing server load and supporting a diverse range of clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If server-side operational transformation is used to support thin clients, then collaborative editing functionality is provided, but server resource consumption increases and scalability deteriorates
Solution Approach 1:
The patent introduces an OT proxy as an intermediary component between the server and thin clients. The proxy performs operational transformation locally, converting server mutations into client-applicable transformations without requiring the server to directly handle transformation logic for each client. This mediator approach enables thin client support while preserving server resources.
2Reliability
If operational transformation is performed on the server for each client update, then sequential correctness is maintained, but network latency increases and user experience deteriorates
Solution Approach 1:
The system performs preliminary operational transformation at the proxy level before updates reach the client. By pre-transforming server mutations into client-specific transformations and caching them locally, the system ensures sequential correctness is maintained while eliminating the need for real-time network round-trips during the transformation process.
3Productivity
If smart clients perform local operational transformation, then update speed increases, but compatibility with thin clients is lost
Solution Approach 1:
The patent implements local quality by enabling operational transformation capabilities at the proxy level specifically for thin clients, while smart clients can continue to perform transformations locally. The proxy adapts the transformation approach based on client capabilities, providing smart client-level performance for capable clients and proxy-mediated transformation for thin clients, thus maintaining both update speed and client compatibility.
Data Source
AI summary
Systems and methods are disclosed herein for an operational transformation proxy for a thin client. The systems and methods may be used for collaboratively editing an electronic object such as an electronic document from a thin client. A first request is received at an OT proxy from the thin client to make a first change to a first version of the electronic object. A first mutation, including the first change to the first version of the electronic document, is created. A second mutation is received at the OT proxy from the server. At the OT proxy, the second mutation of the electronic object is converted into a third mutation of the electronic object based on the first mutation.
