Q
If there are N routers from source to destination, the total end to end delay in sending packet P(L-> number of bits in the packet R-> transmission rate) is equal to ______________
AA. N
BB. (n*l)/r
CC. (2n*l)/r
DD. L/r
Correct Answer:
B. B. (n*l)/r
Explanation:
The equation to find the end to end delay when no. of bits, transmission rate and no. of routers is given by (N*L)/R. The total end to end delay, that is, nodal delay is the sum of all, the processing delay, queuing delay, transmission delay and propagation delay.
