Some time back we were talking about anycast being a bad thing on DNS Root servers. It was suggested by that conversations typically take only one path as a result of CEF-like caching. I noted that providers were working on per packet load balancing. Well, here it is, in the "major vendor": Per-Packet Load Balancing http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s21/pplb.htm So, it seems that we need to review whether the use of anycast on the root nameservers is a good idea. I suggest that we ignore for the momeent anyway the question of whether the deployment of anycast was done with adequate technical analysis, discussion, and approval, and just consider whether we should continue doing it. However, the Root server operation and oversight issues are very important should also be discussed, too, but probably by different forums. --Dean ---------- Forwarded message ---------- Date: Tue, 18 May 2004 19:03:52 -0400 (EDT) From: Dean Anderson <dean@xxxxxxx> To: Paul Vixie <vixie@xxxxxxx> Cc: ietf@xxxxxxxx Subject: Re: Root Anycast On 18 May 2004, Paul Vixie wrote: > Careful design by whom?

Do you mean "Careful Design" like the non-standard changes in Bind 9 AXFR and IXFR? I don't think we can take too much of that sort of thing in the operation of the root servers before we have serious problems. Unilateral action is not a good thing. There is no point in having an IETF (Remember the "Internet __Engineering__ Task Force" in IETF) if you just implement whatever you think OK at the moment (AXFR mods, IXFR mods, Anycast, and probably more that we just don't yet know about) --Dean -- Av8 Internet Prepared to pay a premium for better service? www.av8.net faster, more reliable, better service 617 344 9000 _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
