Packet delivery

Packet delivery

The successful delivery of a packet over a NetWare network depends on the proper addressing of the packet. To send a packet, the sender must know the full IPX address (network, node, and socket) of the recipient. The address is specified in the packet's medium-access protocol and IPX protocol address fields. Once the sender has the recipient's address, it can address the packet. The way the MAC header of that packet is addressed, however, depends on the network's topography. Specifically, it depends on whether the sending node and the destination node are separated by a router. The effect of network topography on IPX addressing is discussed in the following sections.
