In this case, the >conference bridge gave approval for his course of action ("*ok uh, you need >to return to LaGuardia? turn left heading of uh two two zero.*" - ATC) Once he declared an emergency, he had the right of way over all other traffic. ATC would move anyone in his way out of the way. Under <http://en.wikipedia.org/wiki//wiki/U.S.>U.S. <http://en.wikipedia.org/wiki//wiki/FAA>FAA FAR 91.3, "Responsibility and authority of the pilot in command", the FAA declares:[2] * (a) The pilot in command of an aircraft is directly responsible for, and is the final authority as to, the operation of that aircraft. * (b) In an in-flight emergency requiring immediate action, the pilot in command may deviate from any rule of this part to the extent required to meet that emergency. * (c) Each pilot in command who deviates from a rule under paragraph (b) of this section shall, upon the request of the Administrator, send a written report of that deviation to the Administrator. Just because we have checklists doesn't mean we can't think on our feet and handle situations not contemplated in checklists, but checklists and procedures exist to ensure we don't forget something we need to remember. They aren't a substitute for creativity and logical thought. They are an aid to it to ensure a minimum of creative thinking is needed to solve problems which shouldn't exist in the first place. -Robert SEL&MEL+I "Well done is better than well said." - Benjamin Franklin

IPv6 Training
by Marty Anstey 28 Dec '09

28 Dec '09

Greetings, Just wondering if anyone has had any experience with IPv6 training courses. A quick search turns up a few results on the subject, but it would be handy to hear if anyone has any firsthand experiences or recommendations. We're based in western Canada but don't mind traveling a bit, but alternatively an online course would be acceptable as well. -M

IPv6 allocations, deaggregation, etc.
by George Bonser 25 Dec '09

25 Dec '09

We have decided to initiate the process of becoming IPv6 capable. We have requested and received a block of addresses which, after reading some of the discussion here, I fear may be too small to suit our needs (a /48). To better understand how to proceed and in an attempt to get it right (or close to right) the first time, I am soliciting opinions and comments from other network operators. It appears from earlier discussions on this list that while many networks will not filter a /48 announcement in their routing tables, others will. We have data centers and offices in three regions of the globe; North America, Europe, and Asia/Pacific. We are also multihomed as well as having some direct peering. I can break my /48 into /56 nets for each facility. My thought process here being that if I have the same transit providers at all sites, I can announce the /48 from my primary location and that would get announced by the transit provider. They would also accept my more specific routes but not announce them outside of their AS. So traffic originating outside of my transit provider would flow toward them following the /48 and they then move the traffic to the final destination based on the more specific and in the case the traffic has no more specific route, hand the traffic to my main location for me to sort out or just black hole it. There are two problems with this approach. 1: We are unreachable from anyone filtering a /48 and 2: I could see a situation where traffic crosses the Pacific, is handed to my transit provider, and then crosses the Pacific again to get to the destination resulting in poor performance. So it now seems to me that maybe a larger block might be the best answer but being an "end user" the policies seem pretty restrictive on getting a /32 though I might qualify for several /48 blocks (at least one in each registry region). So how does one reconcile having a diverse, multihomed organization on several continents while at the same time trying to do the right thing, not requesting more resources than we need, and trying to be friendly to the various networks' operations by advertizing only what we need to? Is it unreasonable to get separate /48 blocks for operations in Europe, North America, and Asia or possibly two for Asia (one in China and one for Asia outside of China)? While that still won't help us with connectivity from networks filtering /48's, it might relieve much of the back and forth transit across oceans to get traffic originating from and destined for the same continent to stay there. I don't have a problem with regional backhaul tying an office /56 to a data center announcing a /48 and using that data center as a communications hub for the region. It also assumes a transit provider I am paying to haul my traffic will take "more specifics" for internal use even if they aren't advertizing them. I am just trying to minimize the stupidity and barriers to scale on my side of the equation.

RE: IPv6 allocations, deaggregation, etc.
by George Bonser 24 Dec '09

24 Dec '09

Apologies in advance for the top post. My initial idea was to use a /48, divide it up into /56 nets for each facility with /64 subnets within each facility. We would announce a /48 to our transit providers that I would expect them to announce in turn to their peers and we would also announce the more specific /56 nets to the transit providers that I would expect them not to announce to their peers. My current vlan requirements per facility would support such an addressing plan. In order to make that work, we would need the same transit providers in each region as our locations are not meshed internally. We don’t have dedicated connectivity from the US to the UK or China, for example. Currently that is not a problem as far as connectivity is concerned as my US providers appear in Europe and my China provider appears in the US. BUT when I consider the possibilities of South America and Africa and finding a transit provider that has a robust presence everywhere, my choices are very limited. I need to be multihomed and I need to be provider agnostic in my addressing. Using that scheme above does create some potential performance issues. While my transit provider collects the traffic from a remote location and routes it to the more specific location in my network, If a provider in Europe, for example, sees only the /48 announced from the US, maybe they haul the traffic across an ocean to a point where they peer with my provider … who then must haul it back to Europe to the /56 corresponding to the destination because the original traffic source doesn’t see my /56 unless they are using the same transit provider I am. Then based on earlier discussion on the list a while back, I was concerned that a /48 wasn’t even enough to get me connected to some nets that were apparently filtering smaller than a /48 but my mind is somewhat eased in that respect and I believe that a /48 announced from space where /48s are issued will be accepted by most people. Then I was informed of ARIN 2009-5 which seems aimed at our situation; data centers widely separated by large geographical distances that are fairly autonomous and aren’t directly connected by dedicated links. It now seems that we (and the rest of the Internet) might be better served if we get a RIPE AS and net block for our Europe operations, and APNIC AS and net block for our APAC operations and get a regional /48 that I can split into /56 nets for the various satellite facilities within that region as those satellite offices CAN be directly connected to the regional data center which would act as the regional communications hub. There are probably 16 different ways to slice this but I would like to get it as close to “right” as possible to prevent us having to renumber later while at the same time not taking more space than we need. A /48 per region seems like the right way to go at the present time. So we would have a /48 for the US, a /48 for Asia (and possibly one /48 dedicated to China) and a /48 for Europe. Satellite facilities would collect a /56 (or two or three) out of that regional block for their local use. Then I am free from being nailed to the same providers globally and have less chance of traffic crossing an ocean twice. The probability of needing 200 /48s in the next several years is pretty slim and do not warrant our getting a /32 when currently three or four /48 nets will fill the requirements. Thanks again for the input, Mick.

A /48 becomes too small, a /32 very much borderline. Is this a similar scenario for you? How are you justifying a /48 vs a /32?

The cost of nines
by Eric Brunner-Williams 24 Dec '09

24 Dec '09

Hi all, On the 7th of next month I'll be participating in an ICANN consultation on the proposed draft registry agreement, and the number of "nines" that have crept into it, relative to what was expected of new registry operators a decade ago, is one of the hidden cost increases I will discuss with ICANN's lawyers, who are responsible for the extra nines. I'm looking for sources of cost-per-nine, network provisioning, and host provisioning, where "host" is usually a bunch of boxen, not just a pizza box. The way the requirements are now, a startup of another .museum, say for libraries or archives, or a new .coop, or a new linguistic and cultural say a .scot, has to provide a higher level of performance than Verisign currently does for com/net/name, which is slightly absurd, if not worse. I can cite sources, or not, as preferred, and while CORE is comfortable at any number ICANN's lawyers can come up with under the theory that "more nines is what security and stability mean", my goal is to allow real startups, like .museum and .coop were in 2001, not be forced to outsource registry operations to an already highly capitalized registry service provider, for competition policy reasons. I'm also "in the market" for recent failure data, such as Ultra's yesterday, and Verisign's v6, not for competitive reasons, but to show that the SLA expectation of ICANN's lawyers may need modification if placed proximal to actual operational failure data. Off-list or on, and thanks in advance, from my Yule tree to your own. Cheers, Eric
