Given the data-bits m = 11010110 , determine the number of k (parity-bits) by using Hamming Code requirements. Illustrate the error detection and correction scheme using Hamming code method, for both the sender and receiver to detect an error at the following positions: a. 6 th bit position . b. 11 th bit position . Assume an odd-parity scheme for this problem. You must show detailed calculations to receive full-credit.

Prob.4 A digital transmission system sends strings of binary (0 or 1) bits through the channel to the receiver. Assume that the probability of a bit error in the channel is 10-2 and that a string of 1000 bits is transmitted (a) Calculate the probability that more than three bit errors will occur in the 1000 transmissions (b) Use the Poisson approximation to calculate the probability that more than three bit errors wil occur in the 1000 transmissions.

1. For TCP end-to-end flow control, suppose the capacity of the
receiver buffer is 10 packets. Suppose the packets that are being
queued in the receiver buffer are packets 4, 5, 6, 7, 8, 10, 11.
What is the advertised window size the receiver sent to the sender?
Suppose packet 12 is the last packet sent by the sender. What’s the
effective window size at the sender? Can the sender send out packet

6. (10 points) TCP Suppose a TCP Reno sender (congestion avoidance, fast retransmit, fast recovery) has an ssthresh 16 and a cwnd - 4. The sender has no outstanding unacknowledged segments and 240 more segments left to transmit. In addition, the receiver currently has an empty socket buffer that can hold up to 32 segments, and will continue to advertise a receiver advertised window that can hold 32 segments. Assume that there is no further loss of any segments or...
