ECN-capable TCP-friendly layered multicast multimedia delivery combines explicit congestion notification (ECN) with the TCP-friendly layered multicast scheme. TCP-Friendliness denotes that receiver-driven architecture behaves under congestion like the TCP protocol. Unlike well-known TCP-friendly protocols (TFRC, TFMCC, WEBRC), which use TCP throughput the equation, our system assures TCP-friendliness...
Multimedia applications have been widely developed. These applications use TCP-friendly congestion control mechanisms. One of the congestion control mechanisms which multimedia applications use is the TCP-friendly rate control (TFRC). This mechanism is designed for wired networks which any packet loss indicates congestion loss and the sending rate is reduced correspondingly. In this paper, we propose...
In a traditional network stack, data from an application is transmitted in the order that it is received. An algorithm is proposed where information about the priority of packets and expiry times is used by the transport layer to reorder or discard packets at the time of transmission to optimise the use of available bandwidth. This can be used for video conferencing to prioritise important data. This...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
Layered multicast protocol (LMP) is designed for simultaneous and real-time multimedia content distribution to large number of disparate receivers across the heterogeneous Internet. In order to behave properly in the Internet, in particular to be friendly towards TCP, LMP control their rate by adapting to the estimated target rate. TCP-equation model and packet-pair probe are two popular techniques...
