Control Device Analyzes Dropped Packet Descriptors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packet data networks struggle to effectively identify and mitigate the causes of packet drops, which can lead to data errors, communication degradation, and poor network performance.
Innovation Solution
A control device subscribes to receive data from a network device, analyzes descriptors associated with dropped packets to determine a dropped packet profile, and generates notifications to initiate corrective actions based on the identified causes of packet drops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet data networks route packets along a path between source and destination, then data transmission is enabled, but packet losses occur leading to data errors and communication degradation
Solution Approach 1:
The system performs preliminary actions by collecting packet drop data and analyzing descriptors before complete communication failure occurs. The control device subscribes to receive data about dropped packets and proactively analyzes patterns to identify causes, enabling preventive mitigation before reliability severely degrades.
Solution Approach 2:
The system implements feedback by continuously monitoring packet drop events, analyzing the data descriptors, identifying causes, and transmitting notifications to network devices to perform corrective actions. This closed-loop feedback mechanism enables the network to self-correct and improve packet delivery reliability over time.
2Measurement precision
If the control device analyzes descriptors and determines dropped packet profiles to identify causes, then accurate identification of packet drop causes is achieved, but additional data processing time and computational resources are required
Solution Approach 1:
The system segments the analysis process into distinct components: collecting packet drop data, analyzing descriptors to identify patterns, determining dropped packet profiles, and identifying causes. This segmentation allows parallel processing of different data types and enables the system to achieve high measurement precision without excessive sequential processing time.
Solution Approach 2:
The system performs partial analysis by focusing on specific descriptors and packet drop patterns that are most indicative of cause identification. Rather than analyzing every possible parameter, the control device selectively processes the most relevant data elements, achieving sufficient accuracy while minimizing processing time and resource consumption.
3Productivity
If the control device generates notifications to cause corrective actions, then network performance is improved and quality of service is enhanced, but additional communication overhead is introduced
Solution Approach 1:
The system applies local quality by transmitting notifications only to specific network devices that are identified as having problems based on the dropped packet profile analysis. Rather than broadcasting to all network devices, corrective notifications are targeted only to the relevant local devices, minimizing communication overhead while maintaining high network performance.
Solution Approach 2:
The system implements self-service by enabling network devices to automatically perform corrective actions based on received notifications without requiring manual intervention. The notified devices autonomously diagnose and correct their own problems, reducing the need for extensive communication between control devices and minimizing overall network overhead.

AI summary
A control device may subscribe to receive data from a network device. The data may be associated with a plurality of packets that have been dropped by the network device and include a first descriptor based on a type of packet drop associated with a packet of the plurality of packets that have been dropped by the network device, and one or more second descriptors based on a packet flow associated with the plurality of packets that have been dropped by the network device. The control device may determine a dropped packet profile associated with the network device, based on the first descriptor and the one or more second descriptors. The control device may generate a first notification based on the dropped packet profile associated with the network device and transmit the first notification to cause an action to be performed based on the first notification.
