La posibilidades de interactividad propias de la IPTV (e.g., video bajo demanda, pago por ver, E-Learning), hacen prever, a corto plazo, el fortalecimiento de su presencia en el país. Esa masificación, sumada al hecho de ser un servicio que se presta en tiempo real y a su reconocida sensibilidad a la latencia, los retardos y la pérdida de paquetes, constituyen un reto para proveer un servicio que reúna las expectativas de calidad de sus usuarios. En esa tarea, administrar la prioridad en el tráfico puede ser fundamental. Los mecanismos de QoS (Quality of Service) pueden ser un gran aliado, al permitir el manejo rápido de aplicaciones de misión crítica. El artículo inicia con una visión general de la IPTV, sus servicios y arquitectura; la presentación de algunos conceptos aplicados al tema (e.g. QoS, QoE, IPTV sobre ADSL) y cierra con la presentación de mecanismos de calidad de servicio aplicados a IPTV y una valoración de la situación de dos proveedores de este servicio en Colombia.

Abstract The quality of online education is of interest to universities around the world. Only high quality and cyclical evaluation are the conditions for obtaining students’ satisfaction with this form of education. In the pandemic era, digital dissemination and open education have become a special obligation of academic education. This paper aims to present the opinions of postgraduate students on the quality of e-learning forced by the Covid-19 pandemic. The study was conducted using an online survey questionnaire sent to all 173 MBA and Executive MBA (EMBA) students studying during the pandemic era in Poland's leading Business School, 40% of whom returned completed valid surveys. Students assessed aspects of e-learning such as teaching materials, communication with lecturers, the attractiveness of online classes, networking, strategies, and criteria for evaluating didactic activities, e-learning platform, and support received from the university. The results showed that although most examined aspects are perceived very well or well by the students, there is always some space for improvement. Despite the fact that the study was conducted on a small sample of students, their opinions obtained during the survey provide valuable information to universities about the quality of postgraduate e-learning from its main actors, that is, students. Based on this, the paper presents clear recommendations to universities on how the quality of online education could be managed and improved.

Qos Evaluation

The quality of service (QoS) evaluation of heterogeneous networks is an interesting area of research. The traditional QoS evaluation methods usually use a set of network-centric parameters for the performance evaluation of these networks. As a result, using such methods it is not possible to report a comprehensive performance review of networks that would include diverse applications and technologies. To resolve this issue, in this research, a novel approach has been proposed that applies dynamic significance weights and unified metrics of the QoS-related parameters to various applications and technologies present within a heterogeneous network. The result analysis shows that by applying this methodical approach, the performance evaluation of heterogeneous networks can be carried out systematically and efficiently.
