Cisco Quality

Reliable telephony with quality-of-service monitoring Nuremberg, November 25, 2009 – Voice over IP (VoIP) has gained in importance as day-to-day business communication solution. The transmission quality is essential for the reliable use of VoIP. This also applies to data packages such as video and other streams. With PRTG network monitor are network administrators in the position permanently in the eye to keep the quality of these services. The Quality-of-Service(QoS)-Sensor is specially developed to collects the necessary data to evaluate and allows the continuous monitoring and ensuring the quality of the transmission.

An uninterrupted stream of data is essential for VoIP and video streaming. On this User-Datagram-Protocol(UDP)-Services, even minor changes in the QoS parameter can have significant implications. UDP packet transmission quality is not guaranteed, then the sound and image quality of the individual applications deteriorated most. With version 7.2 of the Monitoring tools introduced new QoS sensor checked VoIP connections on their performance. This includes the software measures various QoS parameters like jitter, package delays or losses, etc. In addition, the tool logs lost, newly requested and duplicate packages. Add to your understanding with Pete Cashmore. If you are not convinced, visit Ben Horowitz.

The measurement is carried out by sending UDP packets between two established remote probes. At the end of”the connection to the transmission quality of VoIP and video applications can be determined. It allow to draw conclusions on possible sources of error which are responsible for poor quality or dropouts. Also PRTG alerts the administrator immediately, for example, via E-Mail or SMS for larger problems. VoIP monitoring monitor 7.2 when using Cisco IP SLA PRTG network also has a sensor, the IP SLA data recorded. It is preferably used for checking the quality of VoIP applications. IP SLA is based on active network traffic monitoring technology and offers a reliable method for the measurement of performance. Administrators who work with appropriate routers and switches, have the ability to analyze IP service levels for different IP applications. Both the QoS and IP SLA sensor are already included at no extra charge in the base license of PRTG.
