Automated Latency Detection in Communication Network Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers face challenges in detecting and troubleshooting latency increases in communication network paths, leading to customer complaints due to slower data traffic caused by rerouting to backup paths with higher latency, which can render delay-sensitive applications unusable.
Innovation Solution
An automated latency measurement system, comprising a latency manager that monitors communication paths, detects latency increases, and switches to secondary paths with lower latency, dynamically setting thresholds based on data traffic and failure detection criteria, to maintain optimal network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated latency measurement and monitoring is implemented to detect latency increases, then network performance can be optimized and customer experience improved, but system complexity and measurement overhead increase
Solution Approach 1:
The patent introduces an intermediary measurement system that operates between the data network and transmission network. This measurement apparatus acts as a mediator to detect latency changes without disrupting normal data traffic flow, resolving the contradiction by adding monitoring capability while maintaining network operational simplicity through dedicated measurement paths.
Solution Approach 2:
The patent segments the network monitoring function into separate measurement apparatus distinct from the core data network infrastructure. By dividing the monitoring function into independent measurement entities that can be deployed separately, the system gains latency detection capability without increasing the complexity of the primary network system.
2Loss of time
If latency measurements are continuously monitored to detect increases, then latency issues can be identified timely, but measurement overhead and network traffic increase
Solution Approach 1:
The patent implements periodic latency measurements rather than continuous monitoring. The measurement apparatus performs latency checks at defined intervals, allowing timely detection of latency increases while reducing measurement overhead and energy consumption compared to continuous monitoring approaches.
Solution Approach 2:
The measurement apparatus uses existing network infrastructure and protocols to perform self-measurement of latency. By utilizing available network resources and built-in measurement capabilities, the system reduces external measurement overhead while maintaining effective latency detection.
Data Source
AI summary
An approach for providing latency measurements for a communication path of a transmission network is described. Measurement of latency associated with one or more communication paths of a transmission network is initiated. An increase in the latency within the transmission network is detected based on the latency measurement. One or more secondary communication paths of the transmission network are determined to address the latency increase. One of the secondary communication paths is selected according to a latency threshold.
