4) Sequence Number of TCP SYN Segment : 0[Stream index: 0]

Sequence number: 0 (relative sequence number) Header length: 40 bytes Flags: 0x002 (SYN)

Th SYN Flag is set to 1 and hence it is identifies the segment as a syn segment.

5) Sequence Number of TCP SYNACK Segment : 0 Acknowledgment Field Value in SYNACK Segment : 1 The value of the ACK field in the SYNACK segment is got by adding 1 to the initial sequence number of SYN segment from client computer. Both the SYN ACK flags are set to 1 and hence it is identified as a SYNACK segment.

[Stream index: 0] Sequence number: 0 (relative sequence number) Acknowledgment number: 1 (relative ack number) Header length: 40 bytes Flags: 0x012 (SYN, ACK)

6) Sequence number of the TCP segment containing the HTTP POST : 1Note : I looked in the data field while analyzing the packet which contained the "POST"

word. Sequence number: 1 (relative sequence number)

8) Length of the first six segments =1448

9) Minimun amount of buffer space advertised =28960The reciever window size increases till 182528No the sender is never throttled.

10) There are no retransmitted segments since all sequence numbers are increasingin the inspection.
