Consider a fictional six-layer protocol hierarchy where layer 1 is the lowest layer, and layer 6 is the highest layer. Therefore, an application sends a message M by passing it to layer 6. All the even-numbered layers attach a trailer Ti (i = 2, 4, 6) to their payload, and all the odd-numbered layers attach a header Hi (i = 1, 3, 5) to their payload. Draw the headers, trailers, and original message M in the order they are sent out.
