- RE: NETBIOS vs NETBEUI
- Session API vs Transport Protocol
-
- Actually, IBM invented all this stuff and they are often the source of
- the confusion between NETBIOS the API and the NETBIOS Frames Protocol
- (aka NETBEUI).
-
- NETBIOS the API came on the scene with the first IBM PC Network
- Program. The hardware was a Sytek designed broadband card that used an
- Ethernet data link chip and outboarded the transport protocol to the card's
- processor.
-
- When IBM finally launched their Token Ring hardware and the PC LAN
- Program (note the subtle insertion of "LAN") this transport protocol got a
- dose of 802.2 LLC type 2 connection oriented data link. The original token
- ring support software came with two primary files:
- TOKREUI.SYS and NETBEUI.EXE
- where TOKREUI was the Token Ring card driver, and NETBEUI was the transport
- TSR.
- In the next version, IBM changed the packaging and created the
- currently known LAN Support Program, and changed the software files to
- the current DXMxxx.SYS scheme.
-
- If you read the IBM LAN Tech Reference (SC30-3383), the Transport
- protocol is described there as the "NETBIOS Frames Protocol". Only the
- industry has dubbed it "NETBEUI" after the original file name.
-
- NETBIOS the API has been alse defined on OS/2, and implemented
- on many transports stacks: TCP/IP (RFC1001/1002), DECnet (in PATHWORKS),
- NBP (from 3Com), SPX/IPX (Novell), OSI (TOP NETBIOS)...
