The figure below shows a network of four clients: A, B, C, and D, connected through a router, X. The transmission rate of each device and length of each link are shown on the figure. In addition, the processing delay of the router is 200ms. At t = 0, clients A, B, and C each send a packet of size 2 Mbits to Clien D (through the router X).

3. The figure below shows a network of four clients: A, B, C, and D, connected
through a router, X. The transmission rate of each device and length of each
link are shown on the figure. In addition, the processing delay of the router is
200ms. At t = 0, clients A, B, and C each send a packet of size 2 Mbits to Client
D (through the router X). Assume that the propagation speed over all links is 2
x 108 m/s and the router's queue (buffer) is empty.
Calculate the total delay for each packet until they are received at D.
