$**$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. $$ A varying bandwidth for each segment: $1$ Mbps$,2$ Mbps$,$ and $4$ Mbps$.$ Different distances between segments and routers $($as shown in the image$).3$ Routers with different processing delays as follows: Router $1$: $3$ ms$,$ Router $2$: $4$ ms$,$ Router $3$: $5$ ms$.$ A queuing delay of $2$ ms for each router. $$ A packet size of $1500$ Bytes. $$ Requirements: $$ 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.End System $1$ Segment $1$
