Hello and Good day! We are conducting Bonjour Conformance Test (BCT) for Printer device. BCT result is PASSED but with warning in Multicast DNS, specifically, WARNING: SHARED REPLY TIMING - UNIFORM RANDOM REPLY TIME DISTRIBUTION Other Shared Reply Timing is passed: PASSED: MULTIPLE QUESTIONS - SHARED REPLY TIMING - UNIFORM RANDOM REPLY TIME DISTRIBUTION Environment: BCT Tool Version: 1.5.4 (15400) MacOS Sequioa 15.5 DUT Firmware : Linux Debian 9 Apple mDNSResponder 1790.80.10 Service types: _ipps._tcp, _uscans._tcp, _ipp._tcp, _uscan._tcp Router : NEC AtermWR8370N Setup: 1-to-1 [Mac->Router<-DUT connection] Based on debug.log, this is where WARNING occurs: NOTICE 2026-03-04 10:51:06.870187+0900 _shared_reply_timing 04103: Shared reply response times: min = 26ms, max = 114ms, avg = 65.50ms WARNING 2026-03-04 10:51:06.870361+0900 _shared_reply_timing 04136: 50 percent of the replies within the correct range fell in the interval 20ms and 46ms (should be close to 25%). PASSED (SHARED REPLY TIMING) In the same debug.log for MULTIPLE QUESTIONS - SHARED REPLY TIMING is PASSED: NOTICE 2026-03-04 10:52:29.912334+0900 _shared_reply_timing 04103: Shared reply response times: min = 22ms, max = 112ms, avg = 78.00ms DEBUG_2 2026-03-04 10:52:29.912849+0900 recv_packet 01997: received packet (558 bytes) PASSED (MULTIPLE QUESTIONS - SHARED REPLY TIMING) [Details] Looking at Bonjour_Conformance_Guideline.pdf https://download.developer.apple.com/Documentation/Bonjour_Conformance_Test_Guideline/Bonjour_Conformance_Guideline.pdf there were some differences: In 1.6.2 Expected Result: Test Result File of Test that All Tests Passed, this is not displayed: PASSED: SHARED REPLY TIMING - UNIFORM RANDOM REPLY TIME DISTRIBUTION And in II.8 Shared Reply Timing: (Ideally, 25% of the answers should fall in each 21ms quadrant of the range 20ms - 125ms.) and comparing to the debug.log, there was a discrepancy of the interval, because 20ms and 46ms is 26ms interval. From RFC6762 6. Responding, Ideal range is from 20ms-120ms Because of this, please advise on the questions below: I would like to know on the possible cause and resolution for these WARNINGS. And since in current BCT result, (Test result integrity signature is generated), I would like to know if this is acceptable for BCT certification. Thank you.
