Question

A 100-byte message is sent through a private internet using the tcp/ip protocol suite. If the protocol adds a 10-byte header at each layer, and a 10 byte trailer, what is the efficiency of the system?

Answer 1

Answer:

66.6% efficiency

Explanation:

100 bytes plus 10 bytes per layer header with 5 headers total gives us 150 bytes. 100 / 150 = 66.6% efficiency

Answer 2

Given:

A 100-byte message is sent through a private internet using the tcp/ip protocol suite and the protocol adds a 10 bytes header at each layer

Explanation:

A TCP/IP model has four layers.

Thus at each layer 10 bytes are added

Then,

The total size = 100 + 4×10

                       = 140 bytes

And Efficiency = Message/Total Size

                        = 100/140

                        = 0.7104

Efficiency % = 0.714 × 100

                    = 71.4%

Answer = 0.7104 ,71.4%
