Add "Supported Layers"?
opened this issue · comments
It'd be nice if peers could announce somehow an ordered / conditional list of preferential layers for peering.
I'm thinking:
- Local-only peers could use this to announce that they're available as public peers, but only within geographical boundaries.
- Conditional public peers could announce their existence for members of, for example, a hackerspace.
- Public-public peers could announce themselves but indicate that they only accept peering over Tor, or Wifi, or IP-over-carrier-pigeon.
- Public peers without preferences could simply point out that if you're living somewhere local, it'd be better to use a direct peering system than to tunnel over the clearnet: a peer might have an ordered list of preferences starting with "ethernet/cat6", then "wifi/band:channel", then "clearnet/ipv4", or something.
This would need RFCifying or standardisation, and because each interface might present differently, it might even require multiple peer entries, with a new key indicating applicability, geographical boundaries, or special conditions.
This might seem at first glance like a way of adding conditions to the public peering list that make it less useful, but I think conditions like these would actually make it easier to add a public peer without worrying about becoming an inappropriate global hub.
Of course, that would rely on people actually respecting the instructions given therein, so perhaps a way to announce a peer without actually providing peering credentials, and instead indicating an email address to ask, might also be needed to make it work in practice..
