Assuming that for a given network layer implementation, connection establishment overhead is 100 bytes and disconnection overhead is 28 bytes. What would be the minimum size of the packet the transport layer needs to keep up, if it wishes to implement a datagram service above the network needs to keep its overhead to a minimum of 12.5%. (Ignore transport layer overhead)
- A.
512 bytes
- B.
768 bytes
- C.
1152 bytes
- D.
1024 bytes

Show answer & explanation
Correct answer: D
First, calculate the total connection overhead by adding the establishment cost (100 bytes) and disconnection cost (28 bytes), resulting in 128 bytes. To ensure this overhead remains within the 12.5% limit, the total packet size must satisfy the equation where 128 divided by Size equals 0.125. Solving this yields a minimum packet size of 1024 bytes.
