11. (10 Pоints) A аnd B аre x meters frоm eаch оther, connected to an Ethernet Bus with a 5nsec propagation delay (between A and B) and a bit duration of 2psec for all nodes. A starts transmitting a frame of size P=1GBytes  to B at tA = 1sec. (i) Calculate the time B must have started transmitting its frame given a collision occurs x/10 meters from B. Assume the processing and queuing delay per node is overall is as long as a 20 bit duration. (iii) Argue whether another case exists in which the first bit of a frame sent by A, collides with the 5th bit of a frame by B. (iv) Assume P were a variable. Set up any necessary bounds for P (feel free to set up formulae).
