- IPX and SPX are two separate protocols. The fact that one driver typically
- provides support for both is irrelevant. IPX is a lower level protocol, which
- provides routing, etc. It is comparable to IP. SPX is a higher level protocol
- that provides connection oriented communication. It uses IPX as its lower
- level protocol, and is comparable to TCP. NCP is another protocol, used by
- workstations to talk to a Novell NetWare server. It uses IPX as its lower
- level protocol also. I don't know what it would be comparable to in the TCP/IP
- world (possibly the protocol used by NFS - if I'm not mistaken, NFS does not
- use TCP).
-
- IPX is then used by NCP to carry its traffic to and from the server.
