Nested Bridge for Virtual Desktop Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual desktop environments, especially in nested mode, the inefficient exchange of data between a client device and a second virtual desktop hinders the use of features like printing, USB access, and multimedia redirection, due to the limitations of existing protocols and mechanisms.
Innovation Solution
The establishment of a nested bridge using Inter-Process Communication (IPC) mechanisms between the agent of a first virtual desktop and the client of a second virtual desktop facilitates fast and efficient data transfer, bypassing the need for data to be pushed to the driver level and reducing performance penalties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data exchange between client device and second virtual desktop in nested mode uses traditional protocol virtual channels, then feature compatibility is maintained, but data transfer performance deteriorates significantly
Solution Approach 1:
The patent introduces an intermediary component (virtual channel driver or translation layer) that sits between the traditional protocol virtual channels and the data exchange path. This intermediary translates or bridges data exchanges to enable high-performance direct paths while maintaining compatibility with existing protocol requirements, thus resolving the contradiction between performance and compatibility.
Solution Approach 2:
The data exchange path is segmented into multiple components: traditional protocol virtual channels for compatibility, and a new high-performance path (via virtual channel driver or translation layer) for performance-critical data. This segmentation allows different data types to use different paths, achieving both compatibility and performance.
2Productivity
If nested bridge using IPC mechanisms is established for fast data transfer, then data transfer efficiency is improved, but system complexity increases
Solution Approach 1:
The system components (virtual channel driver, translation layer, or nested bridge) are designed to automatically manage the complexity of IPC mechanisms without requiring manual intervention. The system self-configures and self-manages the high-performance data path, reducing the perceived complexity for users while maintaining high transfer efficiency.
3Adaptability or versatility
If data exchange path is extended through nested virtual desktop configuration, then feature accessibility is improved, but performance penalties increase
Solution Approach 1:
The patent adds a new dimension to the data exchange architecture by introducing parallel paths: the traditional multi-hop nested path (which provides accessibility) and a new optimized path (which provides speed). The new path uses virtual channel drivers or translation layers to create a more direct communication route, effectively adding a dimensional shortcut that maintains accessibility while improving speed.

AI summary
A system is described for establishing a nested bridge to improve data exchange between a client device and a second virtual desktop accessed by the client device through a first virtual desktop in a nested mode configuration. The nested bridge can be established between a virtual desktop agent of the first virtual desktop and a virtual desktop client of the second virtual desktop, both of which can run in the first virtual desktop, to enable fast and efficient exchange of data between the agent and client within the first virtual desktop. The nested bridge can be utilized in conjunction with virtual channels connecting the client device to the first virtual desktop and virtual channels connecting the first virtual desktop to the second virtual desktop for exchanging data between the client device and the second virtual desktop to enable various features.
