Allowed? #11

Closed elear closed 2 months ago

elear commented 4 months ago

*Note:* The current SCION implementation uses the UDP/IP protocol as underlay. However, the use of other underlay protocols is possible and allowed.

This last sentence makes it seem like one might never run SCION on its own. Also, "allowed" isn't a word we should see in RFCs.

[ ] check for instances of allowed (on all three drafts)
[x] clarify that SCION may be run on L2 directly, so the SCION spec is underlay-agnostic. Maybe we could use "lower layer", then define it in the terminology.

Also look at IPv6 "link" as inspiration

This is more complicated than at first sight at the remaining usage of 'allowed' relates to ISD voting rather directly to how the protocol is implemented. There are also numerous references to 'disallow' and 'disallowed' which would also need to be changed.

elear commented 3 months ago

Other cases of allowed and disallowed absolutely should be addressed. In this case we're talking about the nature of the data link. Why is that the concern beyond even the router, much less the AS or ISD?
