Note NetWare 4.0 supports encapsulation of IPX packets in standard IEEE 802.3 frames. Like XNS, RIP derived from work done at Xerox for the XNS protocol family. Using NetWare's LU 6.2 capability, NetWare nodes can exchange information across an IBM network. NetWare packets are encapsulated within LU 6.2 packets for transit across the IBM network. If so, the NetWare shell packages the requests and sends them to lower-layer software for processing and network transmission.
Client applications are unaware of any network access required for completion of application calls.
Services provided by NCP include file access, printer access, name management, accounting, security, and file synchronization. NetWare's NetBIOS emulation software allows programs written to the industry-standard NetBIOS interface to run within the NetWare system. NetWare MHS is a message delivery system that provides electronic mail transport. NLMs are implemented as add-on modules that attach into the NetWare system. NLMs for alternate protocol stacks, communication services, database services, and many other services are currently available from Novell and third parties.
