Consider a 4-layer protocol implementation with application, TCP, IP, and Ethernet layers in that order (top to bottom). Each layer requires a header except the Ethernet layer, which requires a header and trailer. The application header is 16 bytes in length, TCP header 20 bytes, IP header 20 bytes, and let the Ethernet header be 14 bytes, and the trailer 4 bytes

Sketch and label the layered protocol model

Sketch a packet for this system carefully showing and labelling all headers, trailers, and data fields.

Assume a maximum data field for an Ethernet frame of 1500 bytes. What is the overhead (in %) for a 4096-byte application message?

Hint: the message must be segmented into multiple frames and be careful of how you consider the data field in the Ethernet frame.
