IT Interview Questions: What is RAS Protocols ?

A RAS connection running PPP can support the TCP/IP, IPX/SPX, and NetBEUI protocols simultaneously. For example, you may browse a remote network and share files using NetBEUI, browse the World Wide Web using TCP/IP, and access a Novell NetWare file server using IPX--all over a single dial-up RAS connection.

The SLIP protocol is TCP/IP-only and does not support the multitude of options available in PPP. It has fallen out of favor for these reasons and can be avoided in most situations. The NetBEUI protocol will not generally be able to run over the RAS connection unless you have a Microsoft operating system at both ends of the connection. NetBIOS functions such as file sharing, printing, and NetBIOS name service can all be made to work over either a TCP/IP-only PPP or a SLIP connection using NetBIOS over TCP/IP (NBT).
