The Super Socket Net-Lib deals with inter-computer communications and coordinates the secondary Net-Libs – though the TCP/IP secondary Net-Lib is an exception in that it calls on the Windows Sockets 2 API directly. The Banyan VINES, AppleTalk, ServerNet, IPX/SPX, Giganet, and RPC Net-Libs were dropped from MDAC 2.5 onwards. 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.
