Given the message size of 16Kb, packet size of 2Kb, speed of 4Kbps over 3 links, how much time, will it take the message to trav el from the source to the destination considering there are no packet delays?
1 answer:
Answer:
5 seconds
Explanation:
Given that :
Message size = 16kb
Packet size = 2kb
Speed = 4kbps
Number of links = 3
The time taken is calculated using the formula :
[Number of packets + (Number of links - 1)] * (packet size / speed)
Number of packets = message size / packet size
Number of packets = 16kb / 2 kb = 8
Hence,
[Number of packets + (Number of links - 1)] * (packet size / speed)
(8 + (3 - 1)) * (2 / 4)
(8 + 2) * (1 /2)
10 * 1/2
= 5 seconds

Answer:
67%
Explanation:
TCP Header = 20 bytes
IP Header = 20 bytes.
Data chunk = 20 bytes
Adding the 20 byte data chunk to the TCP/IP header makes 60 total bytes.
Total = 60 bytes
Overhead is 40 of the 60
i.e (40/60) * 100 = 66.67 %
