Need help with this computer network homework. Need to create a TCP and UDP client and server program. You can implement the project in any programming language you like. But try to use python and also add screenshots. Thank you...
Project 3: Math Service via Network You are required to implement a math server and a math client. The behaviors of the clients and server in this project are similar to that of the clients and server in Project 1. The client should allow the user to continuously issue requests until the user inputs "Quit". The differences are: Users will input some math expression, such as "2 + 3", 2 *3 The client will send the math expression to the server , 2 + 3 * 4/s", etc., in the client. . The server will evaluate the result of the received math expression, and send back the final result back to the requesting client. The result should be sent back as a string. For example, if the server receives "2 +3", it will send back "5. If the server receives "2 *3, it wil send back "6" Basically, instead of sending strings and receiving capitalized strings, the client will send math expressions and receive the results of the math expressions. You can tell that this project is not very different from the Project 1. You can potentially reuse some part of your original code. On the server side, you need some evaluation function to evaluate a math expression. You can implement our own, or you can use some existing library functions/methods. In either case, your server should support valid math expressions that involve the four basic operators: "+", "-", " and ". The math expressions can have arbitrary number of spaces/tabs within them, and they should still be regarded as valid. Requirements 1. You are required to implement the UDP version. The UDP server should be able to serve multiple clients at the same time by default, without multi-threading. You are required to implement the TCP non-persistent version. The TCP non-persistent server should be able to serve multiple clients at the same time by default, without multi-threading You are required to implement the TCP persistent version without multi-threading. The TCP persistent server should be able to serve multiple clients, not necessarily at the same time. That is, the server should be able to serve one client, and have several other clients pending while it is serving the first client. When the first client is done (quit gracefully), the server can pick up the next pending client and serve it; after this client is done, the server can again pick up the next pending client ant serve it. You are required to submit a project report. In your project report, you should include 2. 3. 4. ehensi to demonstrate that all your programs meet the requirements. For example, for the UDP version, your testing should show that your server really can serve multiple clients at the same time. You can include a screenshot with multiple clients concurrently running and getting the service. Also, show that when a client gracefully quits (by issuing "Quit"), other clients can still get the service without a problem, and new clients can come to get the service without a problem. The project report will have a large weight in terms of grading. You are highly because you are required to implement multi-threading for the group project anyways.
