Question

Question 6 6.25 pts Select the best answer. A client sends five equal sized segments with sequence numbers 15, 35, 55, 75, 95 Segments with sequence numbers 55 and 75 get lost. The server will likely send a segment with acknowledgement number after receiving segment with sequence number 35. None of these answers 55 15 115 35 Question 7 6.25 pts Select the best answer A client sends five equal sized segments with sequence numbers 15, 35, 55, 75,95 Segments with sequence numbers 55 and 75 get lost. The server will likely send a segment with after receiving segment with sequence number 35 sequence number 15 115 55 35 None of these answers Provide a numerical answer. A client sends seven equal sized segments with sequence numbers 15, 25, 35,45, 55, 65, and 75. Segments with sequence numbers 45 and 65 get lost. The client will receive the acknowledgement after the server receives segment #75 number Question 9 12.5 pts Provide a numerical answer. A client has in its sending buffer these equal sized segments with sequence numbers 15, 25,35,45,55, 65, and 75. Based on congestion control and flow control, its offered window is 20 bytes. So far, the client sent segments with Sequence numbers 15,25, and 35. The highest acknowledgement it received is 25. The next segment that the client could send is segment with Sequence number to .(Answer -1 if the client cannot send anymore new segments) C

Answer 1

(6)segment sequence number 15,35,55,75,95
Here,segment size = 20 bytes
lost sequence numbers 55 and 75.
upto sequence number 54 received
Here Acknowledgement number = 55(next sequence needed)

(7)segment sequence number 15,35,55,75,95
Here,segment size = 20 bytes
lost sequence numbers 55 and 75.
upto sequence number 54 received
Here sequence number = No detail given about previous sequence number
None of these answer

(8)segment sequence number 15,25,35,45,55,65,75
Here,segment size = 10 bytes
lost sequence numbers 45 and 65.
upto sequence number 44 received
Here Acknowledgement number = 45(next sequence needed)

(9)segment sequence number 15,25,35,45,55,65,75
Here,segment size = 10 bytes
window size = 20 bytes
Last Acknowledgement number = 25(upto sequence number 24 consumed by server)
client sent segments = 15,25,35.
Hence now server contains data from sequence number 25 to 44(size = 20 bytes)
window full.
Hence no segment will be sent by client .
Answer = -1.
