Subscriber internet routing service [SIRS]

[lakeman]

[aka gateway of last resort]

Serval Mesh lets you communicate with your local neighbours, now it's time to add the capability to route packets globally.

• for control of any potential scalability issues, registration with the gateway should be via invitation only
• the invitation should include the SID and name/IP of the server which should be added to servald config
• servald should send a packet on connection to a network, and every interval to the routing service
• the gateway should remember the IP and port from each incoming packet, and remember the mapping from SID
• IP & port mappings may be serialised and reloaded after a restart
• any packets addressed to a subscriber that is not reachable on the local network should be forwarded to the routing service
