Consider a 4-layer protocol stack with the following layers (numbered 1 to 4 from bottom to top), physical, network, transport, and application. The physical layer uses one-byte flags to mark the start and the end of a packet. The other three layers all use four-byte headers.
-
Sketch the layered protocol model.
-
Sketch a packet for this system carefully showing and labeling all the fields.
-
The transport layer imposes that the maximum packet payload (data portion) for this layer must not exceed 100 bytes other layers have no such restriction. Calculate the percentage overhead assuming a message of 450 bytes is to be transmitted
