Abstract
CAVIEDES VALENCIA, Juan Camilo; CAMPO-MUNOZ, Wilmar and CHANCHI GOLONDRINO, Gabriel Elías. QoS Analysis for IPTV in a Software Defined Network Environment. Rev. ing. univ. Medellín [online]. 2020, vol.19, n.36, pp.29-51. Epub Aug 31, 2021. ISSN 1692-3324. https://doi.org/10.22395/rium.v19n36a2.
The massive deployment of services supported on the video streaming technology brings with itself the expansion of the data networks and the growth of the bandwidth necessary for carrying information. This demands greater control capabilities and network management that guarantees the quality of the service (QoS) for the final user. Such a demand has pushed the innovation of network architectures. Generating thus software-defined networks (SDN), network architecture paradigm where the data and control blueprints are uncoupled. This article analyzes the QoS metrics of a real and emulated SDN network for one of the video streaming services such as the television over the IP protocol (IPTV). The results show the possibility of equaling the QoS of a conventional architecture while offering other advantages for the network such as centralized logic and programmability at the management level.
