چکیده

A voice over IP quality monitoring architecture based on the development of the VQuality library is described. VQuality implements the E-model and its extensions for objective voice quality measurement. The library also supports generation of a customized voice quality CDR with extensions that permit transfer of call quality parameters measured over different instants of time, besides interacting with a RADIUS server for data collection. The framework is exemplified in the context of the fone@RNP VoIP service and VoIP clients incorporating the new functionality are shown.

A Study of QoS Sensitive Pricing for IP Telephony

While Internet Telephony (IP Telephony) encompasses many different architectures and services, the key idea is the transport of real-time voice traffic over the Internet. IP Telephony architecture [2] allows the entire end-to-end path or a portion thereof to be routed over the Internet. The endpoints are regular personal computers (PCs) that are equipped with IP Telephony software which allows ...

Using optimization to achieve efficient quality of service in voice over IP networks

For Internet Telephony to be a viable alternative to the Public Switch Telephone Network (PSTN), efficient and high quality communications are required. This paper proposes an optimization algorithm that selects parameters like coding scheme, packet loss bound, and maximum link utilization level in a Voice over IP (VoIP) network. The goal is to deliver guaranteed Quality of Service (for voice) ...

Adaptive Voice over IP

We discuss the technical viability of transporting real-time voice over IP networks when the output rate of the speech encoder is adjusted to match the characteristics of the network: speech is coded at low bit rates when the network is congested; at higher bit rates, otherwise. First, issues affecting perceptual QoS are analyzed. The rationale for Adaptive Voice over IP (AVoIP) is explained an...

A Framework For Managing Voice Quality In Networks With IP Phones

This paper presents a framework for managing voice quality in converged voice and data networks containing Internet Protocol based phones (IP phones). It introduces IP phones with voice quality monitoring and testing capabilities. These IP phones support network management capabilities without using conventional network management protocols (e.g., SNMP). Our framework provides basis for support...

An Extension to the Session Description Protocol (SDP) and Real-time Transport Protocol (RTP) for Media Loopback

The wide deployment of Voice over IP (VoIP), real-time text, and Video over IP services has introduced new challenges in managing and maintaining real-time voice/text/video quality, reliability, and overall performance. In particular, media delivery is an area that needs attention. One method of meeting these challenges is monitoring the media delivery performance by looping media back to the t...
