Question:

How does ExtremeZ-IP use TCP/IP and Appletalk?

Answer:

For file sharing, ExtremeZ-IP uses the standard TCP/IP protocols that Apple defines. We support AFP v3.1 for Mac OS X clients and AFP v2.2 for Mac OS 9 clients. We also use the Apple defined AppleTalk, SLP and Bonjour protocols for service discovery.

This allows us to work with the built in file sharing client on the Mac, which makes many things easier and more reliable than requiring our own client.

Most of our customers turn off SFM and rely on ExtremeZ-IP. ExtremeZ-IP does the same things on the server as SFM, creating hidden index files and a set of registry keys, where possible following SFM defined conventions so that 3rd party software can access those registry entries

A key point is that ExtremeZ-IP uses the same file format as SFM to store Macintosh forked files in a single NTFS streamed file. This allows you to move files from an ExtremeZ-IP share, using the Windows Explorer, to an SFM share with complete compatibility and confidence.

Our print sharing has to use its own versions of the TCP/IP protocols for Mac OS 9 since Apple does not define a TCP/IP based set of protocols for printing and printer discovery that allow us to give a TCP/IP based experience that matches the Chooser with AppleTalk. So we adopted LPR and SLP and our own client. On Mac OS X we use Bonjour for that purpose. Although you can use the normal Mac OS X LPR client with Bonjour discovery, we also support automatic PPD downloading which requires installation of our own client.
