Virtual Gateway Dynamic Distribution in SDN
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current residential gateways are complex, prone to failures, and require frequent updates to support new protocols, necessitating frequent user intervention and often necessitating separate devices for each m2m service, which is inefficient and costly.
Innovation Solution
Implementing software-defined networking (SDN) and network function virtualization (NFV) to move complex gateway functionality from residential devices to carrier networks or the cloud, allowing for dynamic distribution and control of virtual gateways, thereby simplifying management and enhancing adaptability to new technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex gateway functionality is implemented in residential devices, then service capabilities are enhanced, but device complexity and failure proneness increase
Solution Approach 1:
The patent extracts complex gateway functionality from residential devices and relocates it to carrier network infrastructure. Virtual gateway functions are implemented on network side equipment, allowing residential devices to operate with simplified hardware while maintaining full service capabilities through network-provided virtualization services.
Solution Approach 2:
The patent introduces a virtual gateway layer as an intermediary between residential devices and carrier networks. This virtual gateway, implemented on network infrastructure, mediates complex protocol handling and service management, shielding users from complexity while preserving full functionality.
2Adaptability or versatility
If gateway functionality is updated frequently to support new protocols, then adaptability improves, but user intervention requirements increase
Solution Approach 1:
The patent enables the gateway system to automatically update and adapt to new protocols through network-managed virtual gateway instances. When new protocols are introduced, the carrier network dynamically provisions updated virtual gateway functions without requiring user configuration or intervention, as the virtualization layer self-manages protocol compatibility.
3Reliability
If separate devices are deployed for each m2m service, then service reliability improves, but system complexity and cost increase
Solution Approach 1:
The patent implements a universal virtual gateway platform on carrier network infrastructure that can dynamically instantiate multiple service functions. Instead of deploying separate physical devices for each m2m service, the virtual gateway provides multi-functional service virtualization, where a single physical infrastructure delivers multiple reliable services through software-defined functions.
Solution Approach 2:
The patent merges multiple m2m service functions into a unified virtual gateway infrastructure. Different service functions are combined and orchestrated within the same network-based virtual gateway platform, reducing the number of separate devices needed while maintaining service reliability through virtualization isolation and management.
