Layered multicast : Performance study of round trip time estimation for TCP-equation model
Ahmad Hanis Mohd Shabli, Suhaidi Hassan, Osman Ghazali · 2007
TCP-friendly layered multicast protocol employs TCP-equation model to estimate target reception rate.One of the parameter of a TCP-equation model is round trip time (RTT).The accuracy of RTT estimation affects the accuracy of target rate estimation and the protocol friendliness towards TCP flows.However, estimating RTT in a large multicast session is problematic due to implosion problems. Consequently, a typical acknowledgement technique is not suitable for layered multicast protocol.Estimating RTT without receiversâ feedback (acknowledgement) will not produce accurate RTT.These have resulted to a number of RTT estimation techniques have been proposed.This research intends to study the current RTT estimation techniques for layered multicast and evaluate their performance.
