Best Regards, Tammy Leino -----Original Message----- From: Leino, Tammy Sent: Tuesday, September 18, 2007 5:19 PM To: 'dhcptest@tahi.org' Subject: DHCPv6 self-test RAND of .1 fails Hello All, Whenever my node generates a RAND value of .1, the TAHItest suite fails for all max retransmission time tests. It seems theTAHI 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 ischosen as .1 in retransmissions: First retransmission RT = IRT + (RAND * IRT) RT = 1 + (.1 * 1) RT = 1.1 Second retransmission RT = (2 * RTprev) + (RAND * RTprev) RT = (2 * 1.1) + (.1 * 1.1) RT = 2.31 Third retransmission RT = (2 * RTprev) + (RAND * RTprev) RT = (2 * 2.31) + (.1 * 2.31) RT = 4.851 The test fails here due to "Actual RT is bigger than theexpected maximum value". I am not sure what the expected maximum valueis. First, can someone comment on whether the TAHI testsuite interprets the RAND values defined in RFC 3315 as inclusive ornon-inclusive? Second, if the values are supposed to be inclusive, cansomeone verify that this is a problem with the TAHI test suite? Best Regards, Tammy Leino213_2.html (attatchment)(tag is disabled)
