| dc.description.abstract | Distribution of information using the multicast in current public network does not guarantee reliable delivery. Reliable multicast is required in applications such as financial transfer, software updates, multimedia delivery, and medical images. Recently there has been a great interest in reliable multicast for transmitting the same information to a group of receivers simultaneously. Unfortunately, most of the existing reliable multicast schemes have scalability problems and do not support real-time traffic.
In this thesis, we present a new reliable multicast transport protocol, called Multiple Tree-based Reliable Multicast protocol (MTRM) for reliable and timely delivery of multicast traffic using IP multicast in a heterogeneous network (included symmetric network and asymmetric network) environment. For each multimedia session, the MTRM protocol maintains a single multicast group and several repair groups, to work in asymmetric network, such as cable modem, or ADSL carriers. A novel special server, Designated Server abbreviated to DS, works as the root of the repair group to be responsible for recovering lost data within its service domain.
In addition, the MTRM is receiver-initiated error detection, hybrid NACK-FEC technique for reliability and based on a hierarchical tree-based structure in which the DS groups the receivers in local regions to avoid feedback implosion. Performance results show that MTRM not only improves throughput and usage of resources but also significantly reduces the processing burden of the sender and end-to-end latency. | en_US |
