Which NetWare protocol works on layer 3-network layer of the OSI model ?

The correct answer is IPX.

Key Points

• IPX (Internetwork Packet Exchange) is a network layer protocol used in Novell NetWare operating systems.
• It is responsible for routing data between nodes on a network, functioning at the OSI model's layer 3 (Network Layer).
• IPX is similar to the IP protocol used in TCP/IP networks but was specifically designed for NetWare networks.
• IPX uses a unique addressing scheme that includes a network number and a node number, ensuring each device on the network can be uniquely identified.
• IPX was widely used in the 1980s and 1990s but has largely been replaced by TCP/IP in modern networks.

Additional Information

• IPX was often used in combination with SPX (Sequenced Packet Exchange), a transport layer protocol that provides connection-oriented communication.
• NetWare Core Protocol (NCP) operates at the session layer (layer 5) of the OSI model and provides file and print services.
• NetBIOS (Network Basic Input/Output System) operates at the session layer and is used for communication in Windows-based networks.
• IPX networks can be configured to use RIP (Routing Information Protocol) for dynamic routing information exchange.
• Despite its decline, understanding IPX is essential for legacy network support and historical knowledge of networking protocols.
