. When you have two different networks, one is ATM (Asynchronous Transfer Mode) Network and the other is legacy Ethernet LAN inter-connected by a layer 3 device, With the help of a detailed diagram describe the process of PDU (Protocol Data Units) creation at each layer and how they communicate between the server in ATM network and client PC in Ethernet LAN. With the detailed diagram you also need to explain each layer of TCP/IP model interact and any sub-layers interact for communication to be successful.
