Análisis y evaluación de los protocolos de enrutamiento multicast sobre multiprotocolo Label Switching aplicado a la provisión del servicio de IPTV.

Abstract

The following work was aimed at the Analysis and Evaluation of Multicast Routing Protocols on Label Swiching Multiprotocol Applying to the Provision of the IPTV Service, at the Provincial General Teaching Hospital Riobamba, we proceeded to perform the tests that allowed us to determine what the protocol is Suitable for IPTV service. For the implementation of the test scenario, there were five Cisco Catalyst 2811 routers, four Cisco 2960 switches, a streaming server, six computers as clients and the feStream IPTV Expert Analyzer software: an exhaustive investigation was carried out using the inductive, deductive method, which was based on the observation of the operation of each protocol and the recording of the measurements that I show by the tester, then the analysis and classification of the data obtained was made. To capture data traffic on the network, free softwares such as: Wireshare, Jperf, CDM were used, which allowed to determine the amount of lost packets, delay and latency within the network, and VLC Media Player for the transmission and reception. As a result it was obtained that the multicast routing protocol suitable for the provision of IPTV service is the Protocol Independent Multicast (PIM) SparseMode (SM) -Dense Mode (DM), when obtaining an average value in audio and video quality of 3.96 / 5, as for the jitter that exists in the transmission of RTP packets, it was 14.91 [ms] and the percentage of packet loss of streaming reached 1.93%. It is concluded that PIM SM-DM is the protocol that provides an acceptable level of audio and video quality by selecting an appropriate algorithm for multicast routing, depending on the bandwidth and the type of link available. As a recommendation for streaming video transmission, the Real Time Protocol (RTP) protocol should be used instead of the User Dtagram Protocol (UDP).
