Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadband networks face challenges in ensuring reliable data delivery for Internet of Things (IoT) devices, particularly in detecting anomalies and initiating mitigation actions to prevent data loss and ensure critical data reaches its destination.
Innovation Solution
A system and method that includes a subscriber premises gateway, an access network router, and a database server within a broadband service provider's network, which identifies and tracks IoT devices using a unique identifier in the IPv6 Flow Label field, detects anomalies, and initiates mitigation actions to ensure data delivery, including alerting subscribers and external monitoring entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional broadband networks are used for IoT data transmission, then network infrastructure is maintained, but data delivery reliability cannot be ensured and anomalies cannot be detected
Solution Approach 1:
The patent introduces a header field as an intermediary element that carries unique identifiers for IoT devices and gateways. This header field enables tracking and anomaly detection without fundamentally changing the network infrastructure, thus improving reliability while minimizing complexity addition.
Solution Approach 2:
The system creates copies of header fields containing unique identifiers at multiple network points (ingress, egress, and intermediate routers). These copies enable anomaly detection through comparison without requiring changes to the original data transmission flow, maintaining infrastructure simplicity while enhancing reliability.
2Measurement precision
If header fields are added to track IoT devices, then data delivery can be monitored, but network processing overhead increases
Solution Approach 1:
The patent extracts only the essential tracking information (unique identifiers in header fields) from the complete data packet, separating monitoring functions from data transmission. This allows precise anomaly detection while minimizing processing overhead by handling only header information rather than entire data packets.
Solution Approach 2:
The system applies partial action by monitoring only the header fields containing unique identifiers rather than processing entire data packets. This selective approach provides sufficient anomaly detection capability while significantly reducing network processing energy consumption.
3Reliability
If real-time anomaly detection is implemented, then data loss can be prevented, but system response time requirements increase
Solution Approach 1:
The patent segments the anomaly detection process into discrete stages: header field addition at ingress, tracking through intermediate routers, and verification at egress. This segmentation allows real-time monitoring without requiring centralized processing of all packets, thus maintaining network throughput while ensuring data delivery reliability.

AI summary
Obtain, from a subscriber premises gateway, a data packet having a header field including a unique identifier for a combination of the gateway and a connected subscriber IP device. Transport the data packet through an internal network of a broadband service provider. Remove the header field after the transporting and prior to the data packet exiting the internal network of the broadband service provider to an external network. Store, in a subscriber internet protocol device data repository of the broadband service provider, data, including the header field, representing transport of the data packet through the internal network of the broadband service provider to the external network. Detect, based on the data repository, at least one of an internal and an external anomaly associated with the data packet. Initiate at least one mitigation action in response to the detecting of the at least one of an internal and an external anomaly.
