The NetWare® Link/PPPTM software subsystem is based on the Point-to-Point Protocol (PPP), a protocol standardized by the Internet Engineering Task Force (IETF). When configured with a synchronous or asynchronous serial interface on a NetWare standalone router or file server, NetWare Link/PPP enables point-to-point transmissions of routed data across transmission facilities between interconnected LANs.
NetWare Link/PPP corresponds to the Data-Link layer of the Open Systems Interconnection (OSI) model, with additional services provided on behalf of the Network layer. It defines the automatic establishment and configuration of serial links, or connections, within router- and bridge-based network topologies.
Data transfer rates of up to 2.048 Mbps are possible, depending on the serial interface used. The only requirements are a full-duplex WAN link and modem status signals. You can use any physical interface, including RS-232, RS-422, RS-423, V.35, or X.21. Additionally, you can use copper, fiber-optic, microwave, Integrated Services Digital Network (ISDN), or satellite leased lines.
NetWare Link/PPP contains mechanisms for link configuration negotiation, call authentication, link error detection and correction, protocol multiplexing, and link header compression and data compression.
