GIR-GVP Port Capacity Test Results Summary
Criteria
System Port Capacity is the maximum number of ports (Port Density or PD) or rate (Call Arrivals Per Second or CAPS) that a GIR-GVP system can handle; this number must maximize the usage of hardware resources, while maintaining all criteria within the predefined threshold.
Because CPU usage is the usual deciding factor for peak port capacity, this section presents results that correlate to CPU usage (and other criteria such jitter buffer and max delta from sample recordings) to track the quality of recording.
The following criteria are required for an installation to reach the 95th percentile of quality analysis, from a sample RTP stream:
- Packet Loss <= 1%
- Max Jitter Buffer <= 30ms
- Max Delta <= 200ms
