Comparing Performance Of SRAMT – LE Vs Other Layerd Encoding Schemes Regarding TCP Friendliness

In this paper we describe a hybrid sender and receiver-based
adaptation 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. SRAMTLE
is using both a TCP model and an AIMD (Additive Increase Multiplicative
Decrease) algorithm in order to estimate a TCP friendly bandwidth share. We
evaluate SRAMT-LE and compare it with a number of similar layered encoding
schemes available to the literature (PLM, RLC, MLDA). Main conclusion of
this evaluation was that SRAMT-LE has friendly behavior against the dominant
traffic types of today’s Internet and has a relative good behavior comparing
with the other layered encoding schemes available to the literature.
