TFMCC-based on a new equation for multicast rate control

摘要

TFMCC (TCP-Friendly Multicast Congestion Control) [3] is a recently proposed protocol for Multicast Congestion Control. TFMCC employs an equation to determine the rate of the Multicast Source. The equation was originally derived for the TCP-Friendly Rate Control protocol TFRC [15], which is a unicast protocol. In this work, we evaluate TFMCC with a new equation derived from an analytical Model that abstracts the behavior of a Multicast source controlled according to the Additive Increase and Multiplicative Decrease (AIMD) strategy. Experimental results show tremendous performance improvement without affecting the TCP-fairness of the protocol.
