[comp.dcom.lans] AppleTalk hierarchy help needed

joel@gould9.UUCP (02/09/87)

Can anyone help me with the AppleTalk hierarchy and how it
relates to the ISO model?

This is roughly what I got from Bob Denny's article in MacTutor
of 11/85:

    1.	Physical	SCC, AppleTalk Personal Network, PhoneNet
    2.	DataLink	ALAP
    3.	Network		DDP + RMTP
    4.	Transport	ATP  (NBP?)
    5.	Session		AFP (Denny didn't mention it, since it didn't exist)
    6.	Presentation	(none)
    7.	Application	LaserWriter driver, any Mac program

The acronyms are
	AppleTalk Link Access Protocol
	Datagram Delivery Protocol
	Routing Table Maintenance Protocol
	AppleTalk Transaction Protocol
	Name Binding Protocol
	AppleTalk Filing Protocol (brand new)

These are handled by the software
	DRVR '.MPP': ALAP, DDP, RMTP, NBP
	DRVR '.ATP': ATP
	AppleShare: AFP

Did I screw up or miss anything?  And just out of curiosity, where does
the Kinetics chop it off, at Level 3 and below?

According to Inside AppleTalk (June 1986), there are slight differences in
what Joel said.  (His original message is prefixed by '> below.)

>    1.	Physical	SCC, AppleTalk Personal Network, PhoneNet
>    2.	DataLink	ALAP
     3. Network		DDP
     4. Transport	RTMP, EP, ATP, NBP
     5. Session		ADSP, ZIP, ASP, PAP
     6. Presentation	AFP, Postscript
>    7.	Application	LaserWriter driver, any Mac program

EP = Echo Protocol, ADSP = AppleTalk DataStream Protocol, ZIP = Zone
Information Protocol, ASP = AppleTalk Session Protocol, PAP = Printer Access
Protocol.
