Hi, I have a question from Rate-Halving Algorithm, which is recently added in ns daily snap shots (ns-2-snapshot-20000716/tcl/test/test-suite-rh.tcl). In the file test-suite-rh.tcl, What does the TCP type "SackRHNewReno" stand for? Does it stand for any modified NewReno version?. Thank you, Srinivas Kurla
