2. (a) Suppose an end device A wants to send a frame containing a black and white image to another end device B. There are a total of 4 routers(R1,R2,R3,R4) in between them. The image being sent is a 1080*1920 pixel image. Every pixel is represented with 1 bit. The processing time(p) of each router in given below: I. R1: p = 1us II. R2: p = 1.5µs III. R3: p = 2µs IV. R4: p = 1us The image is being sent through a link of bandwidth 7 MBPS and device B is 3500 Km away from device A. The signal passes through the link at a speed of 2.5x10^8m/s. Considering there is no queuing time, calculate the total delay for this transmission.
