Simple Analysis of ipx spx Protocol

For online games, some compatibility protocols are very important. Today we will introduce the 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 protocol can be used in large-scale networks such as Novell) and local network 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.

◆ Features of ipx spx protocol.

Ipx spx (Internetwork Packet eXchange/Sequences Packet eXchange, Internet Packet eXchange/ordered Packet eXchange) is a communication protocol set of Novell. The obvious difference from NetBEUI is that ipx spx is relatively large and has strong adaptability in complex environments.

Because ipx spx has considered the problem of multiple CIDR blocks since its design. It has powerful routing functions and is suitable for large networks. When the client accesses the NetWare server, ipx spx and its compatible protocols are the best choice. However, in non-Novell network environments, ipx spx is generally not used. The ipx spx Communication Protocol cannot be used directly, especially in the Windows NT Network and the peer network composed of Windows 95/98.

◆ Ipx spx protocol.

Ipx spx and its compatible protocols do not require any configuration. It can identify itself through the "Network Address. The network address in the Novell Network is composed of two parts: the "Network ID" indicating the physical network segment and the "Node ID" indicating the special device ". The network ID is concentrated in the NetWare server or vro, And the node ID is the ID of each Nic card number ). All network IDs and node IDs are unique "Internal IPX addresses ".

It is precisely because of the uniqueness of the network address that ipx spx has a strong routing function. In the ipx spx protocol, IPX is the bottom-layer protocol of NetWare. It is only responsible for moving data in the network, and does not guarantee whether the data is transmitted successfully or provide error correction services.

When IPX is responsible for data transmission, if the receiving node is in the same network segment, it directly transmits the data according to the ID of the node. If the receiving node is remote and not in the same network segment, or in different LAN), the data will be handed over to the NetWare server or the network ID in the router, continue the next data transmission. SPX is responsible for error-free processing of transmitted data throughout the Protocol. Therefore, we call ipx spx a "Novell protocol set ".

◆ NWLink communication protocol.

Windows NT provides two ipx spx compatible protocols: "NWLink SPX/SPX compatible protocol" and "NWLink NetBIOS", collectively referred to as "NWLink communication protocol ".

The NWLink protocol is the implementation of Novell's ipx spx protocol in Microsoft's network. It inherits the advantages of the ipx spx protocol while adapting to Microsoft's operating system and network environment. Users of Windows NT and Windows 95/98 can use the NWLink protocol to obtain the services of the NetWare server.

If your network is switched from the Novell environment to the Microsoft platform, or the two platforms coexist, the NWLink communication protocol is the best choice. However, when using the NWLink protocol, the "NWLink ipx spx compatibility protocol" is similar to the "ipx spx compatibility protocol" in Windows 95/98. It can only be used as a client protocol to access NetWare servers, if you leave the NetWare server, the compatibility protocol will be ineffective. The "NWLink NetBIOS" protocol can not only transmit information between the NetWare server and Windows NT, moreover, it can be used for communication between Windows NT and Windows 95/98.
