Opis:: Modern Internet serves as a high-performance platform for an ever-increasing number of services. Some of them – video services in particular – are of the broadband variety. So, it is not surprising that segments of networks can rapidly become congested, which may lead to a deterioration in quality. It is hoped that the new MPEG-DASH technique will alleviate congestion. This paper contains an analysis of the new technology’s impact on the quality of service in IP networks. It also explains a new numerical tool QoSCalc(DASH) that has been used to analyze the DASH method in different scenarios. The results are presented graphically and interpreted.

Opis:: With traveling professions and nomadic lifestyles on the increase there is a growing need for comprehensive mobile networking within the Next Generation Network, and the security, reliability and technical independency of the Short Message Service (SMS) is becoming more and more indispensable for business processes. Since competitiveness goes hand-in-hand with this business capability, and methods to determine the quality of this service are becoming equally indispensable. This paper presents possible methods to evaluate the “Completion Rate of SMS” and “End-to-End Delivery Time” and combinations of them (new metric in this paper). A software tool, QoSCalc(SMS), has been developed in collaboration with the authors in order to verify whether service providers are abiding by the Service Level Agreements. The tool has been tested in a real measurement environment and the results are presented graphically here and interpreted.

Opis:: This paper describes a new method for measuring and appraising the quality of the video stream in the video-telephony service in IP environments (VToIP). The method uses the so-called VS Model and belongs to the group of parameter-based measurement techniques (offline operation, i.e. without active measurement). It delivers results that come extremely close to those contained in the corresponding Perceptual Evaluation of Video Quality (PEVQ) curves. The method is quick and easy to use - a convincing argument for using this new QoS measuring method.

Opis:: This paper describes a new measurement method for determining the quality of the IPTV (Television over IP) service. This method uses the latest IPTV Model and is one of a number of parameter-based measuring techniques (offline operation, i.e. without intrusive measurement). It delivers results that come very close to those of the corresponding Perceptual Evaluation of Video Quality (PEVQ) curves. The method is quickly and easily implemented - one of the great advantages of using this method to measure QoS.

Opis:: This paper describes a new measurement method (VS model) for determining the quality of online video services relying on modern H.265/HEVC and VP9 codecs. The said method has been developed on the basis of VQuad-HD curves (according to ITU-T J.341). This model does not refer to signal analysis, but protocol analysis instead. The parameters used are: type of video codec, encoding rate, transport technique, packet loss and burst size. The method may be implemented quickly and easily, which is one of the great advantages when using this method to measure QoS.
