ANALISIS QUALITY OF SERVICE DARI LAYANAN INTERNET PROTOCOL TELEVISION (IPTV)

Abstract

IPTV is convergency product between broadcasting, telecommunication and information technology because given multimedia service which in the form of TV broadcasting, video, audio, text, graphic, and data that transmitted to the customer passing broadband using IP protocol (Internet Protocol). Service that given by IPTV has better quality than convensional TV, such as voice over internet protocol (VoIP), data (internet), and video on demand (VoD). Million people in the world were using IPTV so that this technology has growth more raised and always increase every years. IPTV is supporting by there is quality (QoS/QoE), security, realibility and possible communication two ways or interactivitelly �real time�. So that, Quality of Service (QoS) from IPTV service became main attention that can be save. This research has purpose to analyze QoS (delay, jitter, MOS and throughput) from IPTV service such as VoIP, internet (HTTP, FTP), and IPTV in the simulation. The QoS result from simulation will be compare with standard ITUT (delay, jitter). This research is implementation IPTV service in the OPNET simulator using four scenario, that is: account bandwidth needed from masing service, calculate and compare the QoS value, testing and implementation queue method, and choose the effective queue method. The result of this research is showing bandwidth requirement for downlink and uplink from the services are VoIP 50 kbps (downlink) and 50 kbps, the internet are 54 kbps (downlink) and 54 kbps (uplink), and the IPTV service6538 kbps / 6.5 Mbps (downlink) and 14 kbps (uplink). The QoS result showing that using bandwidth � 15 Mbps, resulting jitter value and delay that can tolera�t e 25o0r ms, the MOS increasing became 200% and throughput 600%. The QoS that resulting from queue method applying on the node SDLAM with bandwidth 8 Mbps, only can decrease the value of delay and jitter 50% - 65% on the VoIP and internet services. Beside that, PQ method became one of the queue method that can be optimalizing of QoS eventhough only decrease the jitter 10%
