Internet Protocol (IP)
Internet Protocol (IP) is a routable
protocol, which works on the Network Layer of the OSI Model and the
Internet layer of the TCP/IP Model. IP provides packet delivery and
addressing for source and destination. Connectionless IP, working
together with the connection-oriented TCP, are the de facto protocol
standards of the Internet.
Because IP is a connectionless service,
it is unreliable and does not guarantee the delivery of data or the
order in which it was sent. However, unlike a connection-oriented
protocols, such as TCP or HTTP, which can be slow when delivering
packets, IP provides a fast delivery of data.
Internetwork Packet Exchange (IPX)
Internetwork Packet Exchange (IPX) is a
connectionless routable protocol, which also works on the Network
layer of the OSI Model and the Internet Layer of the TCP/IP model. It
is responsible for handling the broadcasting issues particular to
NetWare. While most commonly used for a Novell NetWare network, IPX
can also be used for Windows NT networks.
IPX is very efficient, scalable with no
performance issues, contains no addressing problems, and is capable of
being used with Ethernet (1500 byte packet size) and Token Ring (4000
byte packet size) networks using the proper Network Interface Card (NIC)
drivers. However, IPX is largely being replaced by the IP protocol.
NetBIOS Extended User Interface
(NetBEUI)
NetBEUI, which is commonly used for
smaller LANs, is a non-routable protocol and operates on the Network
and Transport Layers of the OSI model. Because NetBEUI is a
non-routable protocol, it is quick and easy to configure.
Configuration is minimal once NetBEUI is installed and bound to a
network adapter. However, since it is non-routable, it cannot
participate in Internet communications and is therefore limited in its
usefulness and scalability.
