PRTG Manual: Monitoring Quality of Service and VoIP PRTG can monitor the Quality of Service (QoS) in a network with dedicated QoS sensors, as well as Cisco IP Service Level Agreement (SLA) and Cisco Class Based Quality of Service (CBQoS). Slight variations of network parameters like jitter, packet loss, or packet delay variation (PDV) usually have only little effect on TCP based services (for example, HTTP, SMTP). But for UDP based services like Voice over IP (VoIP) and video streaming, a steady stream of data packets is crucial. The sound quality of a VoIP call drops dramatically when UDP packets are not received in a timely fashion, or if packets are lost or out-of-order. As a rule of thumb for good quality of service (in a VoIP perspective), you want low measurements for jitter (less than 20 to 50 ms) and PDV (less than 100 ms), and preferably zero measurements for packet loss, duplicated packets, or packets in wrong order. For Quality of Service measurements, four sensor types are available: • Monitors VoIP relevant network parameters by testing network connection quality between two probes. • Monitors VoIP relevant network parameters by testing network connection quality between a probe and a target device at the endpoint of the connection.

Traffic is measured bidirectional. • Monitors VoIP relevant network parameters through IP SLA results from Cisco devices (via SNMP). • Monitors VoIP relevant network parameters by using Cisco's CBQoS (via SNMP). QoS (Quality of Service) Sensors The QoS Sensors monitor the quality of a network connection by measuring the following parameters: • Jitter in ms accord ing to RFC 3550 • Packet delay variation (PDV) in ms according to RFC 3393 • Lost packets in% • Out-of-order packets in% • Duplicated packets in% The QoS sensors measure quality of service by sending UDP packets between two probes.
