I'm not as familiar with QGIS as I would like to be so I'm not going to pretend to be an expert. But.... I would start looking at pgRouting I know this can be done in ArcGIS and I'm sure theres a way in the open source environment. Hope this helps.
You could try using a PostGIS database with topology data type and functions. QGIS also has some topology functionality built in - this could be used if you're looking to have a desktop front end to your platform.
You can use our free converter for changing OSM into a routable network, that splits at all intersections. This means OSM ways are changed into multiple links. Input is OSM XML files, output is for instance SHP. Find it at www.routeware.dk, download section.
