Re: ietf.org end-to-end principle

[DIEGO LOPEZ GARCIA <[e-mail]>]

Hi,

For quite a while I have been asking whoever was willing to pay attention whether the good-ole e2e principle is no longer applicable, and we should start to formulate something like a c2c (where c would stand for “cloud”) or similar principle, and think about how to preserve the desired properties of Internet communication in its context.

Be goode,

Hi,

This brings to mind the Aug. 2000 paper, "Rethinking the design of the Internet: The end to end arguments vs. the brave new world" (D. D. Clark, M. Blumenthal).

Best regards,

Hi,

But the fact that these solutions exist points to a need unmet by existing e2e approaches. Someone in IETF operations had presumably thought out their requirements when this service was procured. Embedding e2e within a solution that satisfies those same operational requirements sounds like a potential IETF WG charter in the making.

I'm sure that the situation as it is now is the result of planning; this solution satisfies a need.

For the IETF as an SDO, this should be a lesson learnt then: we keep developing protocols for an end-to-end world. The world out there is not end-to-end though. (*)

And then people in the IETF wonder why the IETF is becoming more and more irrelevant to the world out there.

It might be time to admit that end-to-end is not the one noble thing to aspire to; but instead to accept deployed reality and develop protocols which are of relevance in the presence of proxies, load-balancers, and more.

Is that a job for "just" a working group? I don't know; it more feels like a cross-cutting job for the entire organisation.

Greetings,

Stefan Winter

(*) Since we all love anecdotes: I remember a Minneapolis IETF when a bar BOF had the topic of "proxy threats" which aimed to create a document stating why proxies (be it web, RADIUS, ...) are evil and should be avoided. Fast forward to this discussion here, and I have to wonder when exactly I slipped into this parallel universe.
