Estimation of call quality for low performance servers
Popis výsledku v původním jazyce
The call quality is an important issue of the modern voice over IP (VoIP) networks. This is given by their inherent "best effort" nature and the fact that any packet can be delayed or lost along the transmission path. To ensure sufficient call quality from the customer's point of view a multitude of approaches can be adopted, i.e. dynamic change of routing, codec swap or packet tagging. For these approaches to be efficient call quality information needs to be accessible on the devices through which the call is routed. Since the local area networks (LANs) do not suffer from underperformance the decision about the transmission strategy should be made on the edge of the local network. For the VoIP traffic the place for this decision is the Session Border Controller (SBC). This paper describes a way of speech quality estimation that is both accurate and performance undemanding making it possible to implement and integrate on low performance SBCs based on open-source software. These SBCs find their application mostly in small remote branches of private or academic institutions that do not require complex features of the proprietary hardware solutions but still need the advanced security and call quality monitoring.
