[Routing] Do I need a routing server?

[王仁侠]

Hi,

I now have set up my own osm server by following the tutorial published on
the osm wiki and it works well.
Now I would like to use OSRM to deal with the routing matter,

How can I Integrate it with my osm map server?  Do i need an other routing
server?
After the path is figured out by the OSRM, do I need to put the path data
into map server and render the map?
or just send the data of path to the client(here is Android, with osmdroid
project), and the client add a layer on its map?

best regards,
