IoT QoS Establishment via Manufacturer Usage Description
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions lack an effective method for IoT devices to inform and negotiate with network infrastructure about quality of service (QoS) parameters such as data type, rate, and latency, often requiring manual administrator input or using best effort services.
Innovation Solution
The method involves using a Manufacturer Usage Description (MUD) identifier to determine QoS parameters, which are then provided to a network policy controller to establish and enforce QoS for IoT devices on communication networks, enhancing the MUD architecture to include QoS settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual administrator input is used to establish QoS for IoT devices, then QoS parameters can be configured, but the system complexity and operational difficulty increase
Solution Approach 1:
The patent implements self-service by enabling IoT devices to automatically generate and communicate their own QoS requirements to the network infrastructure. The device autonomously determines its QoS needs based on its operational characteristics and communicates these parameters without requiring manual administrator intervention, thereby resolving the contradiction between reliable QoS configuration and ease of operation
Solution Approach 2:
The patent applies preliminary action by having IoT devices pre-determine and declare their QoS requirements before actual data transmission begins. The device identifies its QoS needs in advance based on its operational profile and communicates these parameters to the network infrastructure proactively, eliminating the need for manual configuration while ensuring reliable QoS establishment
2Device complexity
If best effort service is used for IoT devices, then network infrastructure complexity is reduced, but QoS performance and reliability deteriorate
Solution Approach 1:
The patent applies parameter changes by transforming the network service model from a generic best-effort approach to a parameterized QoS model. IoT devices communicate specific QoS parameters (such as latency requirements, bandwidth needs, and reliability thresholds) that dynamically adjust network resource allocation, thereby improving QoS performance without significantly increasing infrastructure complexity
Solution Approach 2:
The patent implements segmentation by dividing the network service into distinct QoS tiers and parameter categories. Different QoS parameters are independently negotiated and enforced for different device types and traffic patterns, allowing the network infrastructure to handle diverse QoS requirements through modular parameter management rather than complex monolithic control
3Ease of operation
If IoT devices autonomously communicate QoS requirements, then ease of operation improves, but negotiation complexity with network infrastructure increases
Solution Approach 1:
The patent applies universality by implementing a standardized QoS communication framework that can be universally applied across different IoT device types and network infrastructures. The autonomous communication mechanism uses a common protocol and parameter set that works across diverse scenarios, reducing negotiation complexity through standardization while maintaining ease of operation
Solution Approach 2:
The patent introduces an intermediary component that facilitates QoS negotiation between IoT devices and network infrastructure. This intermediary translates device QoS requirements into network-compatible parameters and coordinates the negotiation process, thereby reducing the complexity of direct device-network negotiation while preserving autonomous device communication capabilities
