Book Description
ABSTRACT: The biggest revolution in networking since the introduction of the World Wide Web (WWW) is Internet Protocol (IP) multicasting. Multicasting is becoming increasingly ubiquitous in today's Internet world. There are many commercial applications, both real-time and non real-time, that are based on IP Multicasting. Many of those applications require reliable delivery of data at the receiver's end for them to be meaningful. Reliable multicast refers to the reliable manner in which a message should reach the group of receivers. It is still an active area of research and has a number of protocols in existence. There are several issues like scalability, error recovery and congestion control that make the design of a reliable multicast protocol difficult. This thesis discusses various reliable multicast protocols in existence and provides a framework for a scalable, reliable, dynamic multicast transport protocol for point to multipoint communication. The proposed protocol provides a sequenced, loss less delivery of data from a sender to a set of receivers. The receivers are split as logical groups with a special receiver called Group Leader controlling the group. The error recovery and retransmissions are performed by the Group Leader, which distributes the processing load of the sender. The logical grouping of the receivers makes the protocol scalable by its architectural design. The protocol provides congestion control algorithms and also mentions the group formation and management techniques. A unique feature of the protocol is the ability of the receivers to reconfigure them to suit the network conditions in case of congestion.
