It seems the TAHI test suite is =interpretting the definition of RAND in RFC 3315 as -.1 to .1 =non-inclusive.Here is the situation for RFC 3315 test #37 when RAND is chosen as .1 in =retransmissions:First retransmissionRT = IRT + (RAND * IRT)RT = 1 + (.1 * 1)RT = 1.1Second retransmissionRT = (2 * RTprev) + (RAND * RTprev)RT = (2 * 1.1) + (.1 * 1.1)RT = 2.31Third retransmissionRT = (2 * RTprev) + (RAND * RTprev)RT = (2 * 2.31) + (.1 * 2.31)RT = 4.851The test fails here due to "Actual RT is bigger than the expected =maximum value". I am not sure what the expected maximum value is.First, can someone comment on whether the TAHI test suite interprets the =RAND values defined in RFC 3315 as inclusive or non-inclusive?Second, if the values are supposed to be inclusive, can someone verify =that this is a problem with the TAHI test suite?Best Regards,Tammy Leino210_2.html (attatchment)(tag is disabled)
