$**$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: $1Mbps,2Mbps,$ 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 $2$: $4$ ms $,$ Router $3$: $5$ ms $.$

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

A packet size of $1500$ Bytes.
