Consider a source node A and destination node C connected to different WANS. Assume three applications namely HTTP,DHCP and DNS are enabled for the users. Let the length of the original user message be 600 bytes. Assume thal four layer model is used for data transfer. Determine the following. (i) The minimum size of the Service Data Unit at the 4/3 interface and the size of the layer 4 Protcol Data Unit. (ii) The minimum size of the Service Data Unit at the 3/2 interface and the size of the layer 3 Protcol Data Unit (iii) The minimum size of the Service Data Unit at the 2/1 interface and the size of the layer 2 Protcol Dala Unit (iv) Compute the efficiency for the layer 3 and layer 2
