I just need #9 and part c and d on #10. Thanks.

9. You have the following data, consisting of three 16-bit words: WO: 1110 1101 1011 0011 W1: 1011 0011 1010 1010 W2: 1000 0010 0010 0001 Compute the checksum (also 16-bits) and provide the value as would have to be inserted in the checksum field of TCP or UDP header. Please write your answer in GROUPS OF FOUR BITS! (e.g. XXXX XXXX XXXX XXXX). 10. Two geographically-located hosts, one in San Francisco, another one in New York are communicating using the stop and wait protocol. The servers are connected via a link with rate Rlink = 1.25 Gbps, and an observed RTT of 60ms. Packets of size L = 1480 bytes are transmitted from San Francisco and New York. Please compute the following: a. What is the transmission time of a packet along this link (i.e. compute dtrans). b. Once a packet is transmitted, when will the last bit arrive at the destination? c. Suppose the ACK packet sent from New York back to San Francisco is so negligible as to take O time to transmit that we don't need to compute its transmission time. How long from the point the packet is transmitted from San Francisco, until we get that ACK packet back from New York? d. What would the utilization be in this particular scenario? (state answer ONLY in percent (%)). 9.
