Youre giving not much information of what you exactly are trying to do.
Do you need to use streetmap data or is local stored data also possible?
Basically a route-solve is handled here:

You do no neet internet. You also could use local street data from whereever you get this, and transform this to a traversable network dataset. With this and the network analyst extension you can solve a route (see linked thread).
