| dc.description.abstract | A convergence between IP and TV known as IPTV gams popularity. Unfortunately, IPTV has limitation, such as using an almost "fully occupied" IPv4, providing private network, and mostly not considering "quality of service". With the availability of higher speed Internet connections and the implementation of newer protocol IPv6 with advanced features, IPTV will become broadly accessible with better view. IPv6 has a feature of Quality of Service through the use of its attributes of traffic class or flowlable, especially for guaranteeing bandwidth and latency for multicast multimedia streaming. Existing implementation of current IPv6 attributes is only to differentiate multicast multimedia stream and non multicast one, or providing the same Quality of Service on a single multicast stream along its deliveries regardless number of users. Problem arose is about sending mUltiple multicast streams on allocated bandwidth capacity and different number of their users under routers. Therefore, it needs a quality of service which operates on priority based for multiple multicast streams. The more users joining a multicast stream, the higher priority for the multicast stream to be forwarded. In this thesis, a new QoS mechanism using IPv6 protocol is proposed as well as QoS structure as IPv6 extension header. QoS structure is an IPv6 extension header which is attached into a multicast stream and brings QoS priority values, whereas QoS mechanism operates in routers to determine whethe incoming multicast datagram is forwarded or not by considering its QoS priority values (in QoS structure). Through a senes of experiments usmg newly available NS3 network simulator, the performance of IPv6 based IPTV could be evaluated. Two different topologies have been used with the following parameters: number of users and bandwidth capacity (including the influence of non multicast stream traffic). The topologies have been evaluated with five mathematical functions models to represent number of users with regards to QoS priority level. The experiments have used three criteria levels (0%, 70% and 100% of routers' queue size) which considers about when queue probability is implemented in QoS mechanism. The experimental results have good QoS performances with three of five mathematical function models (constant, negative linear and negative exponential), and criteria levels of 70% and 100%. With these three models and criteria levels, QoS measurements show increasing throughput, decreasing delay and low jitter. It means that for higher number of subscribers with few numbers of multicast streams (channels) the QoS performances are better than the other two mathematical function models. However, if non multicast traffics are considered, the three models are constant, positive linear and negative linear, and with criteria level 70% and 100%. | en_US |
