X.25 is finally getting its day

In fact, the proposal really is strikingly similar to X.25. On the other hand for the breath of problems that they try to solve it makes sense. On the other hand there really is no reason to create one unified protocol to solve all that at once. IETF's “all that can be done on IP and this is how” is kind of bold statement, as there are applications where only reason to involve IP is marketing, eg. there is little reason to involve IP in various hard-realtime-ish short range IoT-ish things (that one popular hard-realtime safety critical industrial automation protocol involves not only IP but DCOM on top of slightly non-standard ethernet to solve problem that is perfectly solved by RS-485 based bus is another thing)

  "Just always do IP" is because of the existing ecosystem of tools, techniques and so on, which all assume IP because IP is very popular. Almost every application can benefit from this† For every single problem there will be a hypothetical ideal solution that's custom in every way like a bespoke suit, but you (or your customers) probably can't afford that solution and so that's the wrong solution. If IP isn't good enough, I would strongly urge you to go help it be better rather than sit on the sidelines saying people shouldn't bother using IP. Mostly for self-preservation reasons, if it can be done somebody is going to do it, and that might as well be you - if it can't be done you'll end up the expert on why not. † Really often these applications says they use IP to benefit from this ecosystem but they aren't on the Internet, and when you look closer - oops, nobody told the people implementing them about not being on the Internet, so they actually are on the Internet, peeking out from unexpected places.

    That is essentially my point with the exception that there are things that are inherently L2 and thus you don't want to bother with IP or for that mater any other L3 protocol.

Time to dust of my old X.400 and x.500 skills and update my cv then. Sigh I could have had such a cool email address if that had taken off C=UK CN=Nickname - I was third line support for the UK x.400 ADMD and had admin
