Re: [v6ops] Thoughts about wider operational input

[Vasilenko Eduard <[e-mail]>]

Hi Jordi,

I understand the desire to fix broken things. (I doubt it is possible)
But why NPT+ULA is not enough for MHMP now?
It is very similar to what Enterprises and small businesses have now.
They would be happy.

You’re right. Let’s say it in a different way, as may be my first email was not clear on this.


  1.  I don’t think we want again to repeat the NAT problems, so NPT is not a valid solution for me.
  2.  I think in the future almost every site could want to be multihomed, in some cases “n” links active, many other cases just as a backup.
  3.  This means that renumbering is not (probably) a valid choice in any cases.
  4.  Can we make PI work in such “huge scale” scenario?
  5.  Can source-address forwarding work and solve all that, or we need that and/or something else.

Only if we solve this, organizations could learn that NAT with IPv6 is not the solution, but something better that provides the same results, and no need to have “private” addresses, because the way NAT is offering a “different” addressing inside and outside is not NAT per-se, but statefull firewalling.

Jordi

Is it really hncp that we needed here?  I think the key tech we need is source-address-based forwarding, and babel i think has delivered that. Granted, getting that into soho routers is a problem.

Maybe the terminology is not the most appropriate and we should talk about "organizations", because there are many types of networks that have the same problem and those are not enterprises (such as government sites, NGOs, etc.).

The problem is the same regardless of the "size" of the organization. The difference is that "today" most SMEs don't have that problem because they don't have PI, but it may turn the same when they realize that not being PI have renumbering issues if changing the ISP. Of course, again, if we talk about a "small" SME, then may not be an issue, they only have 40 or 50 devices to renumber (your mileage will vary), not easy but not "terrible".

On the rest of Gert comments, definitively I agree, and specially on our big mistake not working further on HNCP.

    What is "an enterprise"?

    My stance on this is that for "largely unmanaged SoHo networks" - which
    could be called "small enterprise" - dual-enduser-ISP with dual-/48 or
    NPT66 gets the job done in an easy and scalable way (HNCP would have
    been great, but IETF politics killed it).

    "Enterprise that truly need their own independent fully managed network
    with multiple ISP uplinks and fully routed independent address space"
    are probably way less than 10 million...

    Half of them do not want Internet access anyway, just access to their
    ALGs that will do the filtering and TLS inspection and everything, and
    then out to the Internet as a new TCP session (= could be done with
    DMZ islands of upstream-provider-allocated space just fine).


    We need to work on our marketing regarding multihoming.  "What is it that
    you get, what is the cost, which of the variants do you want, and why...?"
