scheme for multicast transmission of multimedia data using layered
encoding, which we call SRAMT-LE (Sender-Receiver based Adaptation
scheme for Multicast Transmission using Layered Encoding). The most
prominent features of SRAMT-LE 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. In addition, SRAMT-LE adjusts the transmission rates of the
layers in order to service better the group of the receivers. SRAMT-LE is
using both a TCP model and an AIMD (Additive Increase Multiplicative
Decrease) algorithm in order to estimate a TCP friendly bandwidth share.
With the use of SRAMT-LE, we ensure that sender will transmit TCP
friendly traffic and receivers with different capabilities (in terms of
available bandwidth) are able to receive the multimedia information. We
evaluate SRAMT-LE 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 simulations was that SRAMT-LE
has friendly behaviour against the dominant traffic types of today’s Internet
and treats a heterogeneous group of receivers with fairness.1 aBouras, Christos1 aGkamas, Apostolos  uhttps://telematics.upatras.gr/telematics/publications/sramt-le-hybrid-sender-and-receiver-based-adaptation-scheme-tcp-friendly-multicast
