Design and Evaluation of a QoS-Adaptive System for Reliable Multicasting

Lookup NU author(s): Antonio Di Ferdinando, Dr Paul EzhilchelvanORCiD, Emeritus Professor Isi Mitrani



This document presents and studies a QoS-adaptive system for reliably multicasting messages to all intended destinations, despite possible crashes of the sender and other processes, and communication failures. This is a part of our on-going work on building a QoS-adaptive group communication system to support \textit{application service provisioning} (ASP) where it is typical to purchase network level services, subject to some \textit{service level agreements} (SLA), from an Internet Service Provider (ISP). The reliable multicast protocol studied here is designed for QoS metrics such as absolute and relative latency distributions, and the probability of successful delivery, to be negotiated prior to multicast provisioning. Moreover, the protocol adapts its parameters dynamically in order to minimize the message traffic required to achieve the negotiated QoS metrics. The performance of the protocol is analyzed mathematically under simplifying assumptions. The accuracy of the approximations is evaluated by simulations.
