Computer network programs - repost 2

1. Write a UDP Java socket program that allows a sender to transfer a text file to a receiver using a variation of the sliding window protocol as described below to achieve flow control and reliability. Upload the source code files for the sender and receiver, named as [login to view URL] and groupnameRecv.java. Also upload ONE text file, named as [login to view URL], with 8000 bytes that you used for a successful run with retransmission, and using the example values below. Include screenshots showing all activity at the sender and receiver for that file (screenshots will show filename, buffer sizes, timeout entered by the user, and all program output) named as groupnameSendscreen and groupnameRecvscreen.2. Write a TCP Java client socket program that asks the user to enter names of two Websites. The program will then send a correct HTTP Get request to these two Web sites and put the text of the page received from each site in two separate files. The program should have a separate thread to handle each request so that each request is independent and runs concurrently with the other. At the end of each file, print the current date and time after the page download is completed and the time it took for the request to complete (for example, 11:27 pm November 1, 2013, 21 ms). Upload the source code file for the client, named as groupnameClient.java. Also upload the two files containing the output and date/time and timing results, named as groupnameOutput1 and groupnameOutput2. For further description check the document uploaded NOTE: I have started this project but little challenges and i don't have the time to complete it. I will send the code to the bid winner
