The ScionStack model
The central abstraction of the SDK. What a ScionStack is, how you build one, and how addressing, paths, and underlays all hang off it.
Addressing
How SCION addresses work. The ISD-AS model, how an endpoint is named, and the SDK types you use.
Paths and path policies
Path awareness is SCION's defining feature. What a path is, how to inspect the paths to a destination, and how to choose one.
Transport underlays
How your SCION packets physically reach the network. The UDP and SNAP underlays, and how to choose between them.
