چکیده
This paper presents technology for monitoring and assessment of network QoS parameter for Voice over IP (VoIP) applications in inter-domain environment. The technology is based on automated analysis and description of structures (patterns) of QoS parameter behaviour impacting the VoIP quality: “Quality impairment” patterns, i.e. “outliers” of network delay and packet loss, which predict degradation of VoIP quality, when the network QoS parameter is exceeding some “threshold” value, selected based on the rating factor R of the ITU-T E-

Performance Analysis of Measurement-Based Call Admission Control on Voice Gateways
Abstract Quality of Service (QoS) is critical for the success of real time applications over IP, such as Voice over IP (VoIP). On voice gateways, Call Admission Control (CAC) plays an important role for guaranteed QoS, for it makes decisions on whether and how to deliver the traffic based on different kinds of resources. In our study, we propose the measurement-based CAC model based on the vari...
متن کاملTraffic Analysis for Voice in Wireless IP Networks
In this paper we provide an extensive analysis of voice service in wireless IP networks. Voice traffic is serviced with priority over the rest of the traffic. Hence, we concentrate on the voice traffic in the analysis. We model the packetized voice traffic with Markov Modulated Poisson Process (MMPP), and we propose an analytical framework for its analysis in wireless networks. Also, we created...
متن کاملDeployment of VoIP Technology: QoS Concerns
Voice over IP (VoIP) is an emerging communication service allowing voice transmission over a private or a public IP network. VoIP allows significant benefits for customers and service providers including cost savings, phone and service portability, mobility, and the integration with other applications. Nevertheless, the deployment of the VoIP technology encounters many challenges such as intero...
متن کاملAnalysis of QoS for DVB-RCS-based IP network
Purpose – The internet has been used to transport data in the form of packet. Multimedia applications including voice and video are being sent using the internet. In the past, the internet did not support any kind of sophisticated quality of service (QoS) mechanism. Although the type of service (ToS) field in the internet protocol (IP) header has been present and allowed the differentiated trea...
