IPX Reference Model :

Physical Layer : It is related to the selection of n/w (LAN) depending on components of n/w. It selects Ethernet/Arch net/Token Ring for INSTALLATION.

Datalink Layer : Depending on the type of NIC selected at Physical Layer. Datalink selects IEEE frame format i.e. for Ethernet it selects IEEE 802.3. Datalink Layer combines with Physical Layer in ORDER to form Host to n/w layer

Network Layer : It is based on only IPX Protocol.

TRANSPORT Layer : Like TCP/IP this layer is based on 2 end to end Protocols NCP & SPX.

Application Layer : It is related to the end users such as SAP users & File Server Users. SAP users selects SPX for data trans because it is mainly used for multimedia applications. File Server users selects NCP for data trans as it is related to File Transfer Protocol (FTP).
