Bridge for network communication-network protocol XFile (III)

In the previous issue, we introduced the familiar TCP/IP protocols and the content of IP, IPv6, and TCP Protocols. This section describes the IPX/SPX protocols closely related to Netware servers and games, as well as the IPX routing protocol and SPX protocol.

　　 IPX protocol

Description: Internetwork Packet Exchange (Packet Exchange between networks). IPX is the underlying network protocol that comes with Novell NetWare. It is mainly used to control the addressing and routing of packets within or between the LAN, it is only responsible for the transmission of data packets in the LAN, does not guarantee the integrity of the message, and does not provide error correction services.

Application: When data packets are transmitted in a LAN, if the receiving node is in the same network segment, the data is directly transmitted to the receiving node based on the node ID through the IPX protocol. If the receiving node is not in the same network segment, the IPX protocol can be used to send data packets to the NetWare server and continue transmission. During use, the network administrator can add or configure a static IPX route in the ipx route table by using the corresponding IPX route command, such as "routing IPX add/set staticroute, "routing ipx set global" indicates configuring global IPX route settings.

　　 SPX Protocol

Note: The full name is Sequences Packet Exchange (ordered Packet Exchange). The SPX Protocol is based on Xerox SPP (Sequences Packet Protocol, ordered Packet Protocol) Protocol of Xerox, it is also a network protocol for LAN developed by Novell. In the LAN, the SPX protocol is mainly responsible for error-free processing of the entire transmitted data, that is, error correction.

Application: the SPX protocol is generally used in combination with the IPX protocol described above to form the IPX/SPX protocol. It is mostly used in Netware network environments and online games.

　　 IPX/SPX Protocol

Note: The IPX/SPX protocol is a combination of IPX and SPX protocols. It is a communication protocol developed by Novell to adapt to the development of the network. It has strong adaptability and is easy to install, it also provides the routing function to implement communication between multiple network segments. IPX is responsible for data packet transmission, and SPX is responsible for data packet transmission integrity. In Microsoft's NT operating system, the NWLink IPX/SPX protocol and the NWLink NetBIOX IPX/SPX protocol are generally used, that is, the NWLink protocol, the compatible protocol inherits the advantages of the IPX/SPX Protocol and is more suitable for the Windows network environment.

Application: IPX/SPX protocols can be used in large-scale networks (such as Novell) and LAN game environments (such as anti-terrorism elites and Starcraft ). However, if the IPX/SPX protocol is not used in the Novell Network Environment, IPX/SPX compatibility protocol is used, especially in the Peer network consisting of Windows 9x/2000.

For example, in Windows XP, open the "Network Connection" window and right-click "Local Connection ", select "properties" to open the Local Connection Properties window. Then, click "Install", select the "protocol" component, and click "add; in the displayed window, select "NWLink IPX/SPX/NetBIOS Compatible Transport Protocol" () and click "OK. After installation, you can use it without any settings.
