Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting errant nodes responsible for packet loss in wireless communication networks are time-intensive, not scalable for large service providers, and lack real-time accuracy, leading to prolonged troubleshooting and network downtime.
Innovation Solution
A method and system utilizing a central probe server to establish a TWAMP session with nodes, categorize them as violator or non-violator nodes, and sectionalize violator nodes into silo or daisy chain nodes based on time-domain correlation with network topology, enabling real-time identification and efficient troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional reactive troubleshooting methods are used, then network stability is maintained, but mean time to resolve packet loss increases significantly
Solution Approach 1:
The system performs preliminary actions by continuously monitoring packet loss in real-time and proactively identifying errant nodes before they cause significant service degradation. The proactive troubleshooting mechanism prepares resolution strategies in advance, enabling faster mean time to resolve compared to reactive methods where troubleshooting begins only after service impact occurs.
2Measurement precision
If comprehensive node monitoring is implemented, then packet loss detection accuracy improves, but device complexity increases
Solution Approach 1:
The system segments the network into multiple monitoring domains, each handled by a dedicated monitoring entity that independently tracks packet loss metrics. This segmentation allows comprehensive monitoring of all nodes while distributing complexity across multiple manageable units rather than requiring a single monolithic complex system.
Solution Approach 2:
A central controller acts as an intermediary that collects packet loss data from multiple monitoring entities and performs the complex analysis to identify errant nodes. This intermediary architecture enables accurate packet loss detection across the entire network while centralizing the complex processing logic, preventing complexity from propagating to individual monitoring nodes.
3Productivity
If real-time proactive troubleshooting is implemented, then troubleshooting efficiency improves, but network overhead increases
Solution Approach 1:
The system implements periodic sampling of packet loss metrics at configured intervals rather than continuous monitoring, reducing network overhead while maintaining real-time detection capability. The monitoring entities periodically collect and report metrics to the central controller, which then identifies errant nodes based on these periodic samples, achieving troubleshooting efficiency without proportional increases in network overhead.

AI summary
System and method for identifying nodes with packet loss in a wireless communication network. The method comprises a central probe server—establishing a TWAMP session with a plurality of nodes. The central probe server probes the plurality of nodes for packet loss for a time duration ΔT and categorizes each of the plurality of nodes as one of violator node and non-violator node. A sectionalisation module retrieves a topology of the at least one violator node. The central probe server probes at least one neighboring node of the at least one violator node for packet loss for the time duration ΔT. The sectionalisation module identifies the at least one violator node as one of a silo node and a daisy chain node based on the probe of the at least one neighboring node.
