A Wireshark trace of TCP traffic between hosts A and B indicated the following segments. Host A sent a segment with SYN flag set to B at time 0 seconds. Host A retransmitted the SYN segment at 1 second, 3 seconds, and 7 seconds. There were no further segments sent between A and B. At what time, did host A give up on getting a response from host B? ________seconds!

A Wireshark trace of TCP traffic between hosts A and B indicated the following segments. Host A sent a segment with SYN flag set to B at time 0 seconds. Host A re-transmits the SYN segment at 1 second, 3 seconds, and 7 seconds. There were no further segments sent between A and B. At what time, did host A give up on getting a response from host B?
A Wireshark trace of TCP traffic between hosts A and B indicated the following segments. A sent a segment of 0 bytes data payload to B with FIN flag set, sequence number 1000 and ACK number 500. Later B sent a segment of 0 bytes data with FIN flag set, sequence number 500 and ACK number 1001. What is the state of the connection in host B after receiving FIN from A______________________ and after sending its FIN to A __________________________?
. Suppose Host A sends over a TCP connection to Host B one segment with sequence number 3777 and 1500 bytes of data. Assuming the segment is received correctly, what is the sequence number of the ACK that Host B sents to Host A for this segment? 2.Calculate the the Internet checksum of 0100 1011 1001 1111 and1100 1100 0101 1101. 3.How many control messages are required to close a TCP connection?
Explaination A Wireshark trace of TCP traffic between hosts A and B indicated the following segments. Host A sent a segment with SYN flag set to B at time 0 seconds. Host A re-transmits the SYN segment at 1 second, 3 seconds, and 7 seconds. There were no further segments sent between A and B. At what time, did host A give up on getting a response from host B?
Hosts A and B have a TCP connection with neither side having any unacknowledged data. Now, host A sends two TCP segments back to back to host B. Host B sends an acknowledgement (ACK) for each segment. Host A receives the second ACK, but not the first one. How many packets does host A retransmit?
Given evolution of TCP's congestion window, provide following: a. List the times, at which TCP is in slow start, congestion avoidance and fast recovery states. b. List the times, at which the first packet in the sent flight of packets is lost and indicate whether the packet loss is detected via timeout, or by triple duplicate ACKs. c. List the times at which the value of ssthresh changes and provide the new value of ssthresh.
One host is launching syn flood attacks against a service, identified by the port number and the IP address of a server. This host uses its own IP address rather than spoofed IP addresses to send SYN packets to the service simultaneously. Assuming the network bandwidth is sufficient, what is the maximal number of distinct TCP connections will the server need to maintain for these attacking packets from this host?
Consider the following scenario in which host 10.0.0.1 is communicating with an external web server at IP address 128.119.40.186. The NAT table shows the table entry associated with this TCP flow. What are the source and destination IP address and port numbers at: Points A, B, and C.
Suppose Host A sends two TCP segments back to back to Host B over a TCP connection.The first segment has sequence number 90; the second has sequence number 110. Suppose that the first segment is lost but the second segment arrives at B. In the acknowledgment that Host B sends to Host A, what will be the acknowledgment number?
True or false? With nonpersistent connections between browser and origin server, it is possible for a single TCP segment to carry two distinct HTTP request messages.
Suppose Host A sends two consecutive TCP segments to Host B over a TCP connection. The sequence number of the first segment is 748, and the sequence number of the second one is 995. Determine the size of the payload carried by the first segment. Suppose that the first segment is lost but the second segment arrives at host B. What will be the acknowledgment number of the acknowledgment segment that Host B sends to Host A?
Host A and B are communicating over a TCP connection, and Host B has already received from A all bytes up through byte 126. Suppose Host A then sends two segments to Host B backto-back. The first and second segments contain 80 and 40 bytes of data, respectively. In the first segment, the sequence number is 127, the source port number is 302, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A.a. In the second segment sent from Host A to B, what are the sequence number, source port number, and destination port number?b. If the first segment arrives before the second segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number, the source port number, and the destination port number?c. If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number?d. Suppose the two segments sent by A arrive in order at B. The…
