VoIP Capacity Test Summary Tables

Some capacity test summaries in this section were performed on systems with hardware specifications other than those in Hardware and Operating Systems Tested. Major differences in test results can occur, depending on the CPU model and the number of CPUs that are used.

Certain tests may not be conducted with the hardware specified in Hardware and Operating Systems Tested; the major difference is the CPU model and the number of CPUs being used. The Hardware column in the tables below describes the CPU setup that was used in each test and the observed capacity. The results are based on Next Generation Interpreter (NGi) configured in Media Control Platform (MCP), unless it is stated as GVPi.

VoiceXML_App3 was used for both single server testing and PSTNC testing. See Table: Single Server All-In-One Capacity Testing and Table: PSTN Connector and SSG Capacity Testing.

GVP VOIP VXML/CCXML Capacity Testing

This table shows the fundamental performance of a single physical server process in terms of peak throughput and peak port capacity; either VoiceXML applications for MCP or CCXML for CCP. You can use this table as the first basis of your assessment.

Multiple VMs vs. Multiple MCP Capacity Testing

This table provides a comparison of capacity testing results when multiple virtual machines (VMs) are used versus multiple Media Control Platform instances.

The table below shows the effect of stacking server processes on the same hardware server where there is one MCP associated with a VM instance on the same hardware server. The effect is the increased total port capacity that you can achieve using stacked processes provides a comparison of capacity testing results when multiple virtual machines (VMs) are used versus multiple Media Control Platform instances.
