[Sumover-dev] [svn commit] r4833 - vic/branches/cc/cc

New Revision: 4833

Modified:
   vic/branches/cc/cc/tfwc_sndr.cpp

Log:
decay factor when calculating RTT is set to 0.95 (from ns-2 simulator),
but realised this value is a little aggressive in real-world.

hence, decay factor is set to 99& (i.e., 0.99), meaning that it gives 99% weight
to the previous SRTT and gives 1% to the sampled RTT when calculating RTT.
