Hi, In summary: I have tested, on real packet traces, several variants of the hash algorithm suggested in the Appendix to draft-ietf-6man-flow-3697bis. Of hashes based on the von Neumann algorithm, the one in the draft that's now in the RFC Editor queue still seems best. Note that it is only given as an example algorithm, not a recommendation.
Last month, I found time to run tests using the FNV hash algorithm recommended to me by Donald Eastlake. It's significantly better, but it's still in the process of being socialised in the IETF (draft-eastlake-fnv). The full story: http://www.cs.auckland.ac.nz/~brian/flowhash.html I'm hoping that a student will run further tests as a summer project (that means summer in Auckland, which is December-February). Suggestions for what would be useful to test will be very welcome. -- Regards Brian Carpenter -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
