Advanced TCP/IP

The Novell^® TCP/IP software is now multiprocessor (MP) enabled and multithreaded. The transport layer (TCP & UDP) is completely MP enabled so that the stack can process any TCP/UDP connections on any processor. These features take advantage of the multiple processors available and make the stack scale more than it does on a uni-processor machine.

The Novell TCP/IP stack consists of the following six NetWare^® Loadable Module^TM (NLM^TM) programs:

• tcp.nlm provides the transport layer TCP and UDP interfaces.
• tcpip.nlm provides IP, ICMP, IGMP, Routing, and other networking layer protocols.
• bsdsock.nlm provides the BSD standards sockets interface.
• netlib.nlm is a library for the entire stack.
• nirman.nlm allows you to configure the stack through a browser.
• inetcfg.nlm allows you to configure the stack with the help of tcpcfg.nlm.
• tcpstats.nlm allows you to perform web-based TCP/IP monitoring

  The stack configuration information is stored in sys:\etc\tcpip.cfg and sys:\etc\netinfo.cfg.

  NOTE:  An abend may cause the corruption of both .CFG files, so always make a backup of the files.

The stack provides the TCP/IP protocols as per the Request For Comments. NetWare 6.5 includes the following new features:

• Selective Acknowledgement
• Large Windows
• Multihoming
• Load Balancing
• Fault Tolerance
• Virtual IP Address
• Multiple Default Gateway
• Dead Gateway Detection
• Path MTU Black Hole Detection and Recovery
• Classless IP Addresses
• Non-ARPable Secondary IP Address
• TCP Defend Fin Attack
• NIC Teaming
• Default IP Address
• Pragmatic General Multicast
• Command Line Utilities
