Remote users can access Apple systems via the Internet using the first native PowerPC implementation of the PPP network access standard. Apple has added support for PPP (Point to Point Protocol) to its Open Transport networking system for Mac OS computers, as a move towards its goal of offering Internet access directly from Mac OS.
Open Transport/PPP is the first PPP implementation to run natively on PowerPC-based Mac systems. It allows users connected remotely via TCP/IP or the Internet to use a modem or ISDN adapter to access TCP/IP network services. Open Transport is a framework to extend Apple connectivity to support industry standards. The PPP version can be downloaded from the networking area of Apple's Software Updates Archives (http://www.info.apple.com/swupdates/) or from Apple sites on America Online or Compuserve.
This release marks the completion of phase two of the Appletalk Remote Access (ARA) Roadmap, first outlined at the PC Expo show in June. Phase one was the incorporation of ISDN support in the ARA family. Phase two adds dial-up connections via PPP.
Phase three will consist of version 3.0 of the ARA product line, which will concurrently support Appletalk and TCP/IP over PPP. It will introduce the Open Transport standards support to the Appletalk Remote Access Protocol (ARAP). On PowerPC systems, ARA 3.0, like Open Transport/PPP, will offer the advantages of running in native code.
"Our approach is to include TCP/IP and multi-protocol networking as a standard, built-in feature of Mac OS, which began with the introduction of System 7.5," commented product manager Richard Ford. "We will continue to provide customers with plug and play networking capabilities, while working towards offering seamless Internet access directly from the Mac OS."
Standards supported by Open Transport/PPP are Unix System V Streams, PPP - including Link Control Protocol extensions, authentication protocols and reliable transmission - IPCP (Internet Protocol Control Protocol), and compression of TCP/IP headers for low speed links. In the future, Apple will add support for further PPP standards such as Appletalk over PPP (the RFC 1378 protocol).
Open Transport/PPP requires Mac OS version 7.1 or above, with Open Transport 1.1.1.
The products from ARA phase one are now shipping through retail channels. They are ARA 2.1 client, personal server, multiport server and multiport server PCI.
