Dear all, Thanks Brian for going through all this work, and Tom and Alexandre for providing interesting feedback. In section 3, it may be more interesting to divide Examples of Limited Domain Requirements into networks containing human end-users and networks that don't contain human end-users (su

Andy, and Alex, Yes. I think we need to say more about this aspect. It's clear that a technology boundary is a kind of "natural" domain boundary, but on the other hand we've been overcoming such boundaries for many years (anybody remember Ethernets bridged together over FDDI?). And of course VLANs

Alex and Brian, Any time you have a limited domain layer 2 network (such as a campus Ethernet, or more application-specific networks like Alex was mentioning), one thing that commonly occurs is that people want to use tunnels to interconnect such networks either over the Internet, or alternatively

Hi Brian, Thanks for the draft! I am still concerned about the implications and perceptions this draft might entail. Particularly, I wonder whether this will fracture the Internet (even more) and encourage (even more) protocol ossification by allowing developers and protocol designers to take sho

I read the draft. I find it describes well a state of matters in networking along a Limited Domain paradigm. Maybe some call IP-enabled Limited Domains 'walled gardens'. 4. Examples of Limited Domain Solutions This section lists various examples of specific limited domain solutions th
