All, There is no intention to divide an IP connection into pieces, no matter the entity is a host or router (or called "network edge"). Based on the use cases we have recognized so far, they are applications taken from operator's perspective. Thus, we are focusing on the associated channel used between routers. But you are right, ACH over IPv6 should not be limited between routers. If there is a need of control/mgmt messages transmitted on an IP path, ACH should fit. So the authors encourage people to provide more use cases, to utilize ACH thoroughly. Thanks in advance!

I'm not advocating that it should be, but the prohibition surprises me. What is the reason to restrict this to network nodes such as routers? > Why are some people still differentiating between a "host" and a "router"? My mobile phone is a router, forwarding packets between the 4G/5G network and the connected "internet sharing" clients. My laptop is a router, forwarding packets between VMs, containers, the host OS, internet and peripherals connected over e.g. USB. Even some of the VMs running on the laptop are actually routers, forwarding packets from and to other virtual instances... And all of these changes their role dynamically, based on what application is used, and whenever clients are connected or disconnected, VMs and containers are created and destroyed... You can't know in advance if something is a "host" or a "router", and whatever it is right now, might not be what it is in 5 minutes. To restrict anything to either a "host" or a "router" in this day and age does not make any sense. /Ola (T) -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
