IoT Cloud Migration via Intermediary Packet Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The migration of Internet of Things (IoT) devices to cloud-based computer systems is cumbersome and can cause interruptions in service availability and uptime due to the need for stopping virtual machines, creating new identities, and reconfiguring systems, despite advancements in server virtualization.
Innovation Solution
An intermediary computer system that facilitates data communication between IoT devices and cloud-based systems by exchanging data packages, storing variable mappings, and forwarding them to selected cloud systems based on user commands, load conditions, content types, and time-based criteria using various communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual machine instances are stopped and reconfigured for migration, then service provider flexibility is improved, but service availability and uptime deteriorate
Solution Approach 1:
The patent introduces a network address translator (NAT) as an intermediary component that sits between the IoT device and the cloud-based computer system. This NAT maintains persistent network connections while allowing the cloud system to change underlying virtual machine instances. The NAT translates and forwards data packets between the IoT device and different cloud systems without requiring the IoT device to know about instance changes, thus enabling flexible migration while maintaining continuous service availability.
2Adaptability or versatility
If virtual machine instances are stopped and reconfigured for migration, then cloud system scalability is improved, but migration complexity deteriorates
Solution Approach 1:
The network address translator serves as an intermediary that abstracts away the complexity of virtual machine migration from the IoT device. It handles all the complex operations of stopping instances, creating new identities, transferring data, and reconfiguring systems automatically in the background. The IoT device simply communicates with the NAT, which manages the complex migration process transparently, thus enabling scalability without increasing perceived migration complexity for end users.
Solution Approach 2:
The patent employs copying mechanisms where the NAT maintains copies of connection information and data packets during migration. When migrating from one virtual machine instance to another, the system creates and maintains duplicate connection pathways temporarily, allowing seamless switching between instances without interrupting the IoT device's communication flow.
3Productivity
If direct connection is established between IoT device and cloud system, then communication efficiency is improved, but migration flexibility deteriorates
Solution Approach 1:
The network address translator acts as a transparent intermediary that maintains communication efficiency while enabling migration flexibility. It efficiently forwards data packets between the IoT device and cloud systems with minimal processing overhead, preserving direct connection performance. Simultaneously, it provides the flexibility to change underlying cloud infrastructure by translating addresses and routing packets through different virtual machine instances without requiring direct reconnection from the IoT device.
