Revenue-generating services such as video on demand (VOD) and voice over IP (VOIP) place stringent demands on the network for quality service delivery. Subscriber quality of experience (QOE) can be affected by network issues such as packet loss, jitter, latency, and codec issues such as poor compression, delay, and echo. Service providers have become acutely aware of the need to monitor their networks to maintain quality service delivery, ensure high levels of subscriber QOE, and thereby limit subscriber churn and expensive problem diagnoses.
In the past, monitoring telecom networks required expensive separate test tools or monitoring systems deployed throughout the network. These tools were often difficult to use, did not interface with other OSS systems, and provided limited insight into real network issues.
The Zeugma QOE Monitor is the first in the industry to integrate QOE monitoring right into the network. The QOE Monitor runs in the Zeugma Open Application Sandbox (OAS), a protected environment within the Zeugma Services Node (ZSN). For the first time, service providers do not need to have a separate set of hardware test tools to monitor QOE. Simply add this application into the ZSN without impacting current network traffic or requiring any down-time.
The Zeugma QOE Monitor makes use of the extensive deep packet inspection (DPI) and compute grid resources available on the ZSN. The compute grid provides a federated set of compute resources that can be added to over time as network demands scale. The compute grid also provides a redundant environment to ensure high network availability.
The Zeugma QOE Monitor works hand-in-hand with the Zeugma OSS (ZOSS), which provides multi-node data gathering, archival, and reporting. It also easily integrates with pre-existing operational support systems (OSS) and back-office applications, such as fault management, provisioning, and trouble-ticketing systems, as well as third-party data gathering tools.
