$**$Task $2$: Network delay analysis for Packet $**($LO$1\_$Components and LO$2\_$Models$)$

A company is experiencing delays in its network performance. After investigating their network and routers, the image below and the details illustrate the path of a packet.

The image above shows:

A network topology with four segments and three routers.

A varying bandwidth for each segment: $1Mbp{s}_{s_s}2Mbp{s}_s$ and $4$ Mbps $.$

Different distances between segments and routers $($as shown in the image$).$

$3$ Routers with different processing delays as follows: Router $1$: $3$ ms Router $2$:$4ms$ Router $3$:$5ms.$

A queuing delay of $2$ ms for each router.

A packet size of $1500$ Bytes.

Requirements:

Calculate the overall end$-$to$-$end delay for a packet traveling from End System $1$ to End System $2.$ Consider each segment and router's transmission, propagation, processing, and

queuing delays.

Explain your calculations.
