Network Coded Multicast over Multibeam Satellite Systems

Ip Multicast over Satellite

Satellites have been very successful for digital broadcast, and it is a natural step to develop IP multicast over satellite to explore the potential of the satellite systems. This paper discusses the issues of IP multicast over satellite, based on IP multicast protocols using different satellite communications systems including DVB-S and DVB-RCS. The paper provides an overview of the networking...

Network Coded TCP (CTCP) Performance over Satellite Networks

We show preliminary results for the performance of Network Coded TCP (CTCP) over large latency networks. While CTCP performs very well in networks with relatively short RTT , the slow-start mechanism currently employed does not adequately fill the available bandwidth when the RTT is large. Regardless, we show that CTCP still outperforms current TCP variants (i.e., Cubic TCP and Hybla TCP) for h...

Scalable video multicast using inter-layered superposition and network- coded cooperation over MIMO relay systems

The adoption of scalable video coding (SVC) for video multicast services is a promising solution for providing efficient streaming under channel heterogeneity, since SVC can support quality scalability with high coding efficiency. The scalability allows receivers to experience video quality according to their channel conditions. Nevertheless, the scalable video layers are inter-dependent; if a ...

Multicast Packet Loss Measurement and Analysis over Unidirectional Satellite Network

Packet loss patterns over unidirectional satellite link provide useful information for improving the performance of applications like bulk data transfer to many recipients. In this paper, we present our observations and analysis of packet loss patterns on one-to-many multicast sessions taken over an extended period of time. We collected the packet loss data on four multicast receivers in four d...
