2.Bit stuff the following HDLC frame. The frame is organized by fields in a vertical format. Remember you stuff all fields except the start and end flag fields.01111110 starting flag11111111010101001111100111111000001011001110111111111000001011011101001001111110 ending flag3.For a 10 Mbps data link using 12000 bit frames and assuming that electrical signals propagate at 2.5 x 108 m/s: a. How long does it take to introduce a single frame onto the link? b. How long does it take for the trailing edge of the frame to travel 1620 km? c. What is the total transmission time of this frame from start to finish? d. If an ACK is only 6 bytes long what is the total round trip time from start of frame transmission until the ACK for that frame is received?
