The monitoring agent uses the RTP (Real-time Transport Protocol) performance metric to collect and output packet loss and jitter information. RTP is a network protocol used for delivering audio and video over IP networks. It provides mechanisms for timestamping, sequence numbering, and delivery monitoring, which allow for the measurement of packet loss and jitter. RTP is specifically designed for real-time multimedia streaming applications, which are more sensitive to changes in the transmission characteristics of data networks than other applications. Therefore, RTP performance is a suitable metric for monitoring and collecting packet loss and jitter information.
The other options are not directly related to measuring packet loss and jitter. TCP (Transmission Control Protocol) is a transport protocol that ensures reliable and ordered delivery of data, but it is not typically used for real-time multimedia applications. WSAv (Web Security Virtual Appliance) is a Cisco solution for web security, but it does not measure packet loss and jitter. AVC (Application Visibility and Control) is a technology that monitors and controls network applications, but it does not focus on packet loss and jitter. References :=
