Local Device Driver Preloading for Remote Access Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote access computing environments, managing local device drivers for multiple client devices is inefficient due to memory clogging, time-consuming installation and uninstallation, and delayed delivery of local device functionality, especially when frequent connections and disconnections occur.
Innovation Solution
Optimized management of local device drivers based on historical connection data, including pre-installation and uninstallation strategies, and prioritized handling of driver requests to minimize resource waste and ensure timely delivery of local device functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If local device drivers are installed and uninstalled frequently for each connection, then local device functionality can be delivered to client devices, but memory resources are clogged and processing time increases
Solution Approach 1:
The system pre-installs device drivers on the terminal server before remote access sessions begin, based on historical connection data and device usage patterns. This preliminary action eliminates the need for repeated driver installations during each connection, reducing processing time and memory resource consumption while ensuring drivers are available when needed.
2Productivity
If device drivers are retained in memory for frequently connecting clients, then driver installation time is reduced, but memory resources are consumed
Solution Approach 1:
The system applies different driver retention strategies to different client devices based on their connection patterns and resource requirements. Frequently connecting clients receive prioritized driver pre-loading, while less active clients have drivers managed more conservatively. This localized quality approach optimizes memory usage by allocating resources according to actual need rather than applying a uniform strategy to all clients.
Solution Approach 2:
The system dynamically adjusts driver retention parameters such as memory allocation thresholds and retention durations based on historical connection data, current system load, and predicted usage patterns. This allows the system to optimize the balance between driver availability and memory consumption by changing parameters in response to varying conditions rather than using fixed values.
3Adaptability or versatility
If drivers are pre-installed for all possible devices, then driver availability is maximized, but system complexity and resource consumption increase
Solution Approach 1:
The system pre-installs only the most commonly used device drivers based on historical connection data and usage statistics, rather than all possible drivers. This selective preliminary action maintains high driver availability for typical scenarios while avoiding the complexity and resource consumption of installing every possible driver type.
Solution Approach 2:
The system employs a driver management intermediary layer that intercepts driver installation requests, checks against the pre-installed driver catalog, and either serves the existing driver or initiates on-demand installation for uncommon devices. This intermediary approach maintains simplicity by handling most requests through the pre-configured driver set while providing a fallback mechanism for edge cases.

AI summary
The subject matter of this specification can be implemented in, among other things, a method that includes establishing, by a host server running an application, a connection to a client device; obtaining, based on an identifier of the client device, a profile of the client device comprising an identifier of a local device that was associated with the client device during a prior connection of the client device to the host server; and causing, based on the identifier of the local device, a driver for the local device to be available for execution on the host server, wherein the driver for the local device is to convert data between a data format accessible to the application and a data format accessible to the local device.
