Simultaneous TCP connection initiations are rare, but simultaneous connection termination is relatively common. How do two TCP nodes negotiate the simultaneous sending of FIN packets to one another? Draw the ladder diagram, and label the states on each side. Which node goes into TIMEWAIT state?

For the Zhou-Gollman non-repudiation protocol discussed in the lecture on “Non-Repudiationand Anonymity Protocols”, which one of the following statements is false:

TCP is a sliding window protocol. This means. а. there can be more than one segment "in flight" (sent but no ACK has been received) at a time. O b. the TCP retransmission timer slides up as ACKS are received. O c. there can only be one segment outstanding (sent but no ACK has been received) at at time.

Write a Java TCP MultipleClient-Server Program for following scenario.   NOTE Server Details are in the above figure Client-Server communicates continuously until the Client send Bye to the Server Use Multithreading for Multiple Clients NOTE : 1 cm =  0.39 inches 1 cm =  0.03 foot 1 cm =  0.01 meter   Sample Ouput: Client Server 1 – cm to inches 2 – cm to foot 3 – cm to meter Enter length in cms (int) : 10 Received from Server 3.9 inches   1 – cm to inches 2 – cm to foot 3 – cm to meter Enter length in cms (int) : BYE Received from Server BYE   Client DISCONNECTED Server Waiting for the Cline to be Connected… CONECTION ESTABLISHED   Received From Client 10 cms Sent to Client 3.9 inches   Received From Client BYE Sent to Client BYE     HINT : When client choses 1 for cm to inches and enter 10, then the client sends the string 110 to the Server. Where the first char ‘1’ represents the cm to inches and the other 2 chars represents the 10.
