The recent years have seen an explosive upsurge in the popularity of IPTV networks and the IPTV user base. The increased user base poses new challenges to IPTV provider in providing the IPTV services with the expected QoE to the users due to the increase in traffic and heterogeneity in networks. The VoD, being the most prominent and most lucrative of the triple play components, require efficient managing...
QoS-aware network planning becomes increasingly important for network operators and ISP alike as the number and heterogeneity of applications supported by networks continue to increase. We have proposed an architecture and methodology to support QoS-aware route planning for IPTV networks. The route planning problem was formulated as a residual bandwidth optimization problem and solved using GA-VNS...
QoS-aware network planning becomes increasingly important for large network operators and ISPs as the number and heterogeneity of applications supported by networks continues to increase. This paper proposes a novel approach to performing residual bandwidth optimization with QoS guarantee to support IPTV services on the Internet backbone. The approach combines the use of a new highly scalable hybrid...
The mechanism of channel allocation used in the medium access control (MAC) sub-layer for wireless devices in IEEE 802.11 standard is through a single MAC channel. The drawback with the single channel solution is when the number of nodes increases, the throughput is also reduced. However, using multiple channels solves this problem and increases channel utilisation efficiency, where channel allocations...
A fast loss recovery scheme for IP multicast services is presented in this paper. In this scheme, the head field of retransmission request packets contains the one-way delay between the requestor and the sender of the lost packet, and the head field of repair packets contains the one-way delay between the repairer and the requestor. Each member in the multicast group compares its own one-way delay...
