A new architecture, with N layers, is proposed. User application at the top layer generates a message of M
bytes. At each layer, an H bytes header is added. The second layer of that architecture also adds T bytes trailer.
In this architecture, the message M is not divided into smaller packets at any layer.
• What is the size of the final message (in bytes) transferred by the lower layer?
• If we consider the headers and trailers to be an overhead, what is the percentage of such overhead to
the total size of the final message?
