This means collecting data including network KPIs such as QoS queue utilisation and key statistics for the call manager server, implementing IP SLA tests to measure end to end latency, and gather call data via RTCP to understand actual call MOS, Jitter and latency.
The real-time control protocol (RTCP) addresses the problem of providing a constant bandwidth for the connection from connection source (SRC) to connection sink (SNK) (Schulzrinne et al., 1996).
Mechanisms for video channel control that use RTCP can be accommodated, as well, since RTP and RTCP streams go through the conferencing server.
Information such as effective bandwidth and delay time is sent to a server using RTCP. Following this, the server sends data on RTP after adjusting the quality of the data to suit the communication status.
VQmon is the first VoIP Performance Management software to support the new VoIP management protocols, providing the essential metrics for the International Engineering Task Force (IETF) RFC 3611 (RTCP XR) media path reporting protocol and the QoS reporting protocols for SIP, H.323, MGCP and Megaco.
EVOip+ for Cisco is offered in an active version, which records encrypted calls and works in distributed environments with multiple locations via a single server, at which point the calls are stored on either a standard Windows server or with Linux; or in a passive version, which monitors RTP/ RTCP packets on the LAN and operates independently from the customer's network.
OpenCNC unbundled, open-architecture CNC control has new high-speed machining algorithms, RTCP extensions in five-axis machining, probing cycles for parts inspection, and real-time deterministic Ethernet I/O.

These include the Real-Time Transport Protocol (RTP), Real-Time Control Protocol (RTCP) and the Real-Time Streaming Protocol (RTSP).
Gaithersburg, MD, February 04, 2015 --( GL Communications Inc., announced today its enhanced RTP Testing and Simulation Tool referred to as RTP ToolBox[TM] Software - A tool that helps test, simulate & monitor traffic carried by RTP & RTCP Packets.
