A TCP endpoint can abort the connection, which entails the sending of a RST Packet rather than a FIN. The endpoint then moves directly to TIMEWAIT. To abort a connection using the Berkeley socket library, one first sets the SOLLINGER socket option, with a linger time of 0. At this point an application close() triggers an abort as above, rather than the sending of a FIN.

Network Protocols

A network protocol is a set of rules that govern how data is exchanged between the devices in a network. Network protocols enable communication between devices that are located in different parts of the world. Consequently, they are critical in today's digital communications.

Question

A TCP endpoint can abort the connection, which entails the sending of a RST Packet rather than a FIN.
The endpoint then moves directly to TIMEWAIT. To abort a connection using the Berkeley socket library,
one first sets the SOLLINGER socket option, with a linger time of 0. At this point an application close()
triggers an abort as above, rather than the sending of a FIN.

Write a Java program to create a TCP Socket program to receive an input message from client socket, reverse the input message and send it back to the client. Note that the program should have the comments embedded in it to explicitly explain why that code is being used. Explain in detail the client process and the server process with reference to the code given by you for this task.
I made a TCP server using socket python,basically my server can: - Upload (“put”) request: The client should, at the very least, open (in binary mode) the local file defined on the command line, read its data, send it to the server through the socket, and finally close the connection. - Download (“get”) request: The client should, at the very least, create the local file defined on the command line (in exclusive binary mode), read the data sent by the server, store it in the file, and finally close the connection. To avoid accidents, the client should deny overwriting existing files. - Listing (“list”) request: the client should, at the very least, send an appropriate request message, receive the listing from the server, print it on the screen one file per line, and finally close the connection. I want you to draw an ER diagram that can show the process above please.
in java fx Write a program that launches 1,000 threads. Each thread adds 1 to a variable sum that initially is 0. You need to pass sum by reference to each thread. In order to pass it by reference, define an Integer wrapper object to hold sum. Run the program with and without synchronization to see its effect.
Suppose an HTTP client makes a first GET request to the gaia.cs.umass.edu web server for a base page that it has never before requested, which contains an embedded object, which causes the client to make a second GET request. A very short time later, the client then makes a third GET request - for the same base page, with that third GET request having an If-Modified-Since field (as does the 4th GET request that the client makes for the embedded object). Neither the base object nor the jpeg object has changed. How many round trip times (RTTs) are needed from when the client first makes the third GET request (i.e., when it requests the base object for the second time) to when the base page and the jpeg file are displayed a second time, assuming that: any time needed by the server to transmit the base file, or the jpeg file into the server's link is (each) equal to 1/2 RTT the time needed to transmit an HTTP GET into the client's link is zero? the time needed by the server to transmit…
