RFID Manager for Virtual Machine Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtualization of physical computers in data centers disrupts the one-to-one relationship between RFID transponders and operating environments, leading to challenges in maintaining accurate RFID information for virtual machines.
Innovation Solution
Establishing a virtual machine on a host computer with multiple RFID transponders, determining and storing RFID information, and transmitting it upon request from an RFID reader, utilizing an RFID manager and hypervisor to manage RFID information across the host computer's transponders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If virtualization of physical computers is implemented to reduce machine count, then productivity and resource efficiency are improved, but the one-to-one relationship between RFID transponders and operating environments is lost, causing RFID information accuracy to deteriorate
Solution Approach 1:
The patent segments the RFID information management by creating separate RFID information records for each virtual machine while maintaining the physical RFID transponder as a shared resource. The RFID manager divides the RFID information into multiple virtual records, each associated with a specific virtual machine instance, allowing accurate tracking of RFID data for each virtualized environment independently.
Solution Approach 2:
The patent introduces an RFID manager as an intermediary component between the RFID transponder and the virtual machines. This manager maintains a mapping relationship between physical transponders and virtual machine instances, translating RFID readings into meaningful information about which virtual machine is currently using the transponder, thus preserving RFID information accuracy despite virtualization.
2Device complexity
If multiple virtual machines share a single host computer with RFID transponders, then device complexity is reduced, but difficulty of detecting and measuring RFID information increases
Solution Approach 1:
The patent implements a feedback mechanism where the RFID manager continuously monitors RFID transponder readings and updates the mapping between transponders and virtual machine instances. When a virtual machine is created, migrated, or destroyed, the system receives feedback about the change and automatically updates the RFID information records, ensuring accurate detection and measurement of RFID information despite the virtualized environment.
Solution Approach 2:
The patent creates virtual copies of RFID information records for each virtual machine instance. Instead of trying to physically separate RFID transponders for each virtual machine, the system creates informational copies that represent the relationship between the physical transponder and each virtual machine, making RFID information tracking as easy as managing virtual machine metadata.
