Engineering Contradiction Analysis
1Productivity
If traditional SNMP and Netconf protocols are used for network management, then management of Ethernet-based IT devices is efficient and controlled, but the solution becomes too complex and inefficient for M2M systems with limited processing power and low power consumption
Solution Approach 1:
The patent introduces a gateway device as an intermediary between M2M resource nodes and the network management system. The gateway runs a lightweight binary web service (CoAP) instead of full SNMP agents on constrained devices, translating management operations between the simple binary protocol and traditional SNMP/Netconf protocols. This mediator approach allows efficient management of M2M devices without burdening their limited processing resources with complex protocol stacks.
Solution Approach 2:
The patent changes the protocol parameters by adopting binary web service protocols (CoAP, Efficient XML Interchange) instead of traditional text-based SNMP. This parameter change reduces message size, lowers power consumption for transmission, and decreases processing overhead on M2M devices while maintaining compatibility with existing network management infrastructure through the gateway's protocol translation capabilities.
2Use of energy by moving object
If M2M systems use specialized legacy or proprietary management solutions, then power consumption and processing requirements are reduced, but interoperability and integration with backend IT infrastructure become limited
Solution Approach 1:
The gateway device is designed with multi-functionality, supporting both binary web service protocols (CoAP, EXML) for efficient M2M communication and traditional SNMP/Netconf protocols for integration with backend IT infrastructure. This universal approach allows a single gateway to handle multiple protocol types, enabling M2M systems to benefit from low-power binary protocols while maintaining full interoperability with existing network management systems through the gateway's protocol translation capabilities.
3Adaptability or versatility
If deep low-bandwidth access networks are used for M2M devices, then device deployment flexibility is increased, but network management overhead and complexity increase significantly
Solution Approach 1:
The patent extracts the complex management functionality from the constrained M2M devices and relocates it to the gateway device. The gateway runs the binary web service interface and handles complex management operations, while M2M devices use simple resource description interfaces. This extraction reduces management overhead on devices in deep networks while maintaining deployment flexibility, as the gateway absorbs the complexity of protocol translation and resource management.
4Productivity
If millions of M2M devices are managed in a single domain, then system scalability is achieved, but network load and management complexity increase dramatically
Solution Approach 1:
The patent segments the management architecture by introducing gateway devices that aggregate multiple M2M resource nodes. Instead of managing millions of devices directly from a central NMS, the system hierarchically segments management through local gateways that handle binary web service communications with their attached devices. This segmentation reduces network load by localizing management traffic at gateway level, while only aggregated data and control messages traverse the wider network, enabling scalable management of millions of devices.
