Question

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 travel from the source to the destination considering there are no packet delays?

Answer 1

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
