VoIP Performance Metrics
The ITU has put forth a standard for VoIP monitoring and performance. Visual UpTime Select monitors and measures VoIP specific protocol activity, including RTCP, RTP, H.225, H.245 H.323 and SIP. The ability to do this at both the port and circuit layers equips IT staff with the knowledge needed to analyze the performance of packet voice across the entire infrastructure.
Visual UpTime Select provides:
- Real-time/zero wait time reporting and historical reporting so IT managers can monitor traffic patterns and bandwidth utilization in real–time as well as scroll Back-in-Time
- Site-specific application and network performance information through instrumentation of each location across the infrastructure
As a peer-to-peer application, VoIP requires instrumentation across each site so that IT staff can have visibility into each IP phone conversation and each IP application flow. The Visual UpTime Select AppFlows module provides this visibility.
To assure successful monitoring of VoIP metrics, Visual UpTime Select supports the following passive jitter measurement and SLA metrics:
- End-to-End IP circuit jitter, which reports the daily average of passive jitter measurements on all types of user IP traffic for a selected CoS
- End-to-End IP circuit CoS, service level verification data by reporting on RTD, PDR, jitter if configured and circuit availability for a specified number of days in a month for each Class-of-Service
