Solution
The correct answer is 76.19%
EXPLANATION:
The header of the IP datagram given is in hexadecimal format.
Size of the header is 20 to 60 Bytes
Version = 4 bits = (0100)2 (It is IPv4)
Header length = (0101)2 to (1111)2 = 5 bits to 15 bits
Total length = 216 bits
Identification = 216 bits
Fragment Offset = 216 bits
Time to live = 28 bits
Protocol = 28 bits
Header Checksum = 216 bits
SOLUTION:
IP Datagram = 45000054 00030000 2006.......
4 5 00 0054
The efficiency of an IP datagram can be determined by calculating the ratio of the payload (data) size to the total datagram size.
As we have determined above:
- The total size of the datagram is 84 bytes.
- The size of the header is 20 bytes.
Subtracting the header size from the total size gives us the payload size:
- Payload size = Total size - Header size Payload size = 84 bytes - 20 bytes = 64 bytes
The efficiency of the datagram is then:
- Efficiency = (Payload size / Total size) * 100%
So,
- Efficiency = (64 bytes / 84 bytes) * 100% ≈ 76.19%
Therefore, the efficiency of this datagram is approximately 76.19%.
