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
โ
Correct Answer: (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.
