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{\textquoteright}s Internet and treats a heterogeneous group of receivers with fairness.}, author = {Christos Bouras and Apostolos Gkamas} }
