Abstract

Video streaming over the Internet has become the most sought after application and is growing at a very fast rate. Internet Protocol Television (IPTV) is a technology that has been growing fast, replacing traditional cable TV. With the rapid development in the high speed networks, multimedia streaming over the internet has increased incredibly, of which video streaming is the major source of traffic in the core network. Hence IPTV video streaming over the core network has become one of the active topics for research. The major challenge associated with IPTV traffic is the fact that video traffic requires more bandwidth and is more sensitive to delay and packet loss due to congestion. Lots of research has been done to provide an Admission Control algorithm for IPTV traffic. Admission Control becomes an essential part as it is typically enforced to ensure QoS in the network. It helps prevent bottleneck in the core network. This thesis proposes an efficient method to provide admission control for IPTV traffic in the core network by using multiple GRIP probe packets to check the resource availability in the core network for the new incoming channel request. Moreover, the algorithm proves that using multiple video qualities in the network helps increase the number of channels delivered to the end user, thus satisfying more users, as opposed to single video quality. Using multiple GRIP packets made the proposed method more reliable and it was seen that on an average, the number of channels delivered to the end user was increase over 90%.
