Its components include: Active X Data Objects (ADO), OLE DB, and Open Database Connectivity (ODBC).
The Network Library router had the job of managing all these protocols, however now only the named pipes secondary Net-Lib is managed by the router.
The Super Socket Net-Lib also handles data encryption via the use of the Windows SSL API.
Each Net-Lib supported network protocol has a separate driver (not to be confused with a device driver), and has support for a session layer in its protocol stack.
There are two general types of Net-Lib: the primary and the secondary.
