Cloud Device Endpoint Virtualization for Secure Job Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud computing systems lack secure and efficient methods for accessing and managing device endpoints, such as printers, across off-premise communications networks, leading to limitations in device availability and job routing when endpoints become unavailable.
Innovation Solution
The implementation of a cloud-based print service computing system that registers device endpoints as virtual objects, allowing secure access and job routing through virtual device identifiers and secure device endpoint identifiers, enabling seamless communication and job allocation across off-premise networks, even when physical devices are unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If device endpoints are accessed directly through off-premise networks, then network accessibility is improved, but security and reliability deteriorate due to lack of centralized management
Solution Approach 1:
A cloud-based device service acts as an intermediary between users and device endpoints. The service maintains a virtual device object that stores the secure device endpoint identifier, enabling indirect access through the cloud infrastructure. This mediator ensures centralized management while maintaining network accessibility, resolving the contradiction between ease of operation and reliability.
2Adaptability or versatility
If virtual device identifiers are mapped to secure device endpoint identifiers, then job routing flexibility is improved, but system complexity increases
Solution Approach 1:
The system segments identification into two distinct layers: virtual device identifiers for user-facing operations and secure device endpoint identifiers for actual device communication. The virtual device object stores the mapping between these layers, enabling flexible job routing without exposing the underlying complexity. This segmentation allows adaptability while managing system complexity through clear separation of concerns.
3Extent of automation
If device endpoints are registered with cloud service, then centralized management is improved, but data transmission overhead increases
Solution Approach 1:
Device endpoints are registered with the cloud service in advance, and their secure device endpoint identifiers are stored in virtual device objects before actual job execution. This preliminary action establishes centralized management upfront, allowing subsequent job routing to proceed efficiently without repeated registration overhead. The mapping is prepared beforehand, reducing data transmission overhead during operational phases.

AI summary
A device endpoint is accessed through an off-premise communications network relative to the device endpoint. The device endpoint is registered to a virtual device object in data storage of a device service, the device service and the device endpoint communicating across the off-premise communications network, the virtual device object storing a secure device endpoint identifier of the device endpoint. A virtual device identifier associated with the secure device endpoint identifier of the device endpoint is stored in the virtual device object. A request to access the device endpoint using the virtual device identifier is received. The secure device endpoint identifier associated with the virtual device identifier in the virtual device object is read. The device endpoint is notified of a pending job associated with the secure device endpoint identifier. The pending job is communicated to the device endpoint identified by the secure device endpoint identifier.
