Ratman

This is the documentation tree for the decentralised, delay-tolerant vector routing protocol "Ratman". It's basic design is influenced heavily by protocols such as B.A.T.M.A.N., serval, and others.

In Ratman, all routing is done on IDs that are represented as the blake2 hash of a user's public key. It has a real-time and buffered routing component: routing tables are built in userspace over a list of interfaces and interface specific IDs (not the pubkey!), to associate a pubkey with an interface route. This relationship is further explained in the netmod documentation.

If Ratman isn't able to find a route to a target, or based on various parameters, it will cache a message in the local journal, periodically checking if it can be delivered at a later point in time.
