The lollowing lyme is Facket store and Forward$)$ switchung network$6$ PointsGiven that: whole information size to be transferred is $10$ MB$,$ the packet size is $600$B including $100$B header, the transmission rate is IMbps, all channels $($cables$)$ are IMbps, $1\mathrm{.}5$ Km length and with $2$ x $108$ m see propagation speed. The processing time in each router is $5$psec. Assuming error free channel Find: How many packets are needed? What is the throughput efficiency?What is the transmission time for one packet $($T$)?$ What is the propagation time for one hop $($T$,)?$What is the total transfer time for one packet from Is to Rx$?$ What is the total transfer time for whole packets from Tx to Rx$?$
