Draw a sequence diagram for the following scenario. In a network, two nodes communicate with each other. These are the sequence. 1) Node J sends ping message to Node L 2) Node L sends ICMP echo reply to node L. Now Node A is having the MAC address of Node L. 3) Node J starts TCP handshake with Node L by sending SYN message. 4) Node L sends (SYN+ACK) back to node J. 5) Node J sends the ACK to Node L.

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. d. Suppose the two segments sent by A arrive in order at B. The first acknowledgment is lost and the second acknowledgment arrives after the first timeout interval. Draw a timing diagram, showing these segments and all other segments and acknowledgments sent. (Assume there is no additional packet loss.) For each segment in your figure, provide the sequence number and the number of bytes of data; for each acknowledgment that you add, provide the acknowledgment number.
Please draw a sequence diagram for the following scenario. In a network, two nodes communicate with each other. These are the sequence. 1) Node F sends ping message to Node H 2) Node H sends ICMP echo reply to node H. Now Node F is having the MAC address of Node H. 3) Node F starts TCP handshake with Node H by sending SYN message. 4) Node H sends (SYN+ACK) back to node F. 5) Node F sends the ACK to Node H.

TCP sessions are full-duplex, which means that data can be sent in either direction during the lifetime of the session. Consider a session in which the connection is established, the client sends 100 data segments, all of them are ACKed, and all of the ACKS are received by the sender, then the session is ended by both sides closing the connect. How many segments in total have the SYN bit of the header set to 1? а. 4 O b. 2 с. O d. 1 е. 209
TCP is a connection-oriented protocol. This means that... а. there is a direct physical connection between the two endpoints of a TCP session. O b. both of the endpoints communicating over TCP keep information about the state of the connection. с. both endpoints of a TCP session have to connect to a third party before data can be sent or received. O d. a TCP sender can start sending data to the receiver before the three-way handshake takes place.
Consider a TCP session between Hosts A and B. Assuming that Host A sends a 10byte segment with sequence number 5, what will be the sequence number of the acknowledgment sent from B to A
Consider a client connecting to a web server via a router as shown in Fig.Q2. Client A sends a request to the server to retrieve a 7.5 Mbytes file. Given that the segment size is 50 Kbytes, the round trip time (RTT) between the server and client is 10 ms, the initial slow-start threshold is 16 and the client's buffer always has a storage space of 1 Mbytes. Assume that TCP Reno is used, there is no loss during transmission and the headers of protocols are ignored. 400 Mbps 200 Mbps 400 Mbps Link a Link b Link c Client Web Server Fig.Q2 (a) Describe how the value of sending window changes as a function of time (in units of RTT) during the whole connection time. 2.
14 The following figure shows a TCP transaction. Assume Host A always has data to send, and each packet has size 20 Bytes. Assume Host A has a sending window of 40 Bytes, that is, it can send two "in-flight” packets maximum. Answer the following questions. A. At the time marked "1", i.e., when the first packet times out, will Host A send any packet? if your answer is no, explain why not; if your answer is yes, how many packets will be sent, what are the sequence numbers of them? B. At the time marked "2", i.e., when the ACK of the 2nd packet is received by Host A, will Host A send any packet? if your answer is no, explain why not; if your answer is yes, how many packets will be sent, what are the sequence numbers of them?
