Complete Chapter 10 Case Project 4 “Installation Troubleshooting at North Jetty Manufacturing” (page 496 in print text).  Find a PRODUCT to recommend for each scenario.  (For example, taking frequent breaks from the computer might be a good idea if someone is experiencing discomfort, but there are also ergonomic products which might help the situation.  You are to find one or more of those products for each of the six scenarios.)  For each of the problems listed, include not only your product recommendation, but also the URL that directly takes the reader to the product you are recommending on the Web. (Do not include a URL to the home page of the supplier, but rather the complete URL that links directly to the one product you are recommending.) Also include a link to a web site of reviews of that product. (If the reviews are on the same page as the product itself, note that in your memo).Make CERTAIN that your document is in the form of a memo to Candace Van Camp, as stated in your textbook. (There is a business memo template in Microsoft Word, if you need help with memo format).Spelling, grammar, correct citations, and content will all influence your project grade.

In this programming project, you will be writing sending and receiving data link layer code for implementing a simple reliable data transfer protocol. There are two versions of this project, the stop and wait for version and the GBN version.This project prototypes are protocol3 and protocol5 in chapter 3 the data link layer of the textbook. You should implement the function from_physical_layer() and to_physical_layer() using UDP socket API. You should also implement other functions to make protocol3 and protocol5 runnable. Sender must display variable next_frame_to_send, ack_expected, s.seq. Receiver must display variable frame_expected. Sender will send 9 frames every 10 frames to simulate frame lose.You must submit the following files:The project design document: for example, flow chart and running screen display.Source code and executable file
