Compare gbn, sr, and tcp (no delayed ack). assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding acks can be received (if not lost in the channel) by the receiving host (host b) and the sending host (host a) respectively. suppose host a sends 5 data segments to host b, and the 2nd segment (sent from a) is lost. in the end, all 5 data segments have been correctly received by host b.
(i)-how many segments has host a sent in total and how many acks has host b sent in total?
(ii)-what are their sequence numbers?
(iii)-if the timeout values for all three protocol are much longer than 5 rtt, then which protocol successfully delivers all five data segments in shortest time interval? answer this question for all three protocols.

Write a computer program to calculate the three-phase fault current for a fault at f in figure 1.16, with the network normal, and with one line at a time removedproblems 1.1 write a computer program to calculate the three-phase fault current for a fault at f in figure 1.16, with the network normal, and with one line at a time removed 20 power system relaying from service. the positive-sequence impedance data are given in the accompanying table. use the commonly made assumption that all prefault resistance values are (1.0+j0.0) pu, and neglect all resistance values. calculate the contribution to the fault flowing through the cb b and the voltage at that bus. for each calculated case, consider the two possibilities: cb b2 closed or open. the latter is known as the stub-end fault í• figure 1.16 problem 1.1 system data for figure 1.16 from to positive sequence 0.0+j0.1 0.05j0.15 0.04 j0.2 0.01 jo.i 0.015 + j0.15 0.01 j0.19 0.01 +j0.19 0.03+j0.1 0.0+j0.08 6 6 6 from service. the positive-sequence impedance data are given in the accompanying table. use the commonly made assumption that all prefault resistance values are (1.0 + j 0.0) pu, and neglect all resistance values. calculate the contribution to the fault flowing through the cb b1, and the voltage at that bus. for each calculated case, consider the two possibilities: cb b2 closed or open. the latter is known as the “stub-end” fault.
