SRAMT-S: A hybrid sender and receiver-based adaptation scheme for TCP friendly multicast transmission using simulcast approach

In this paper, we describe a hybrid sender and receiver-based adaptation
scheme for multicast transmission of multimedia data using the simulcast
approach, which we call SRAMT-S (Sender-Receiver based Adaptation
scheme for Multicast Transmission using Simulcast). The most prominent
features of SRAMT-S are its distributed (to sender and receivers) transmission
rate estimation algorithm and its innovative RTT (Round Trip Time)
estimation algorithm based on one-way delay measurements. SRAMT-S is
using both an AIMD algorithm and a TCP model in order to estimate a TCP
friendly bandwidth share. We evaluate SRAMT-S through a number of
simulations in order to examine its behaviour to a heterogeneous group of
receivers and its behaviour against TCP connections. Main conclusion of the
simulation was that SRAMT-S has friendly behaviour against the dominant
traffic types of today’s Internet and treats a heterogeneous group of receivers
with fairness.
