Assignment: Research Handling Multiple Clients

In this assignment, you study the different ways of handling multiple clients.

Using the South University Online Library or the Internet, research how multiple clients may be handled.

Based on your research and understanding, complete the following discussions:

Part 1

Answer the following questions:

In the distributed library application, would you prefer to use select for handling multiple clients? Is it possible to achieve the same task without using select? If yes, discuss various ways of doing this.
Compare the usage of select and accept in your multiclient network programs?

Part 2

Write a program to implement a TCP concurrent server with the following functionalities:

When the client starts up, it should display a menu with the following service choices:
Reversal of the string
Count of words given the separator
Count of characters
Check for palindrome
Provide the required functionality as a switch at the time of client invocation and convey it to the server as a part of the protocol by sending a message.
Once your program is done and running, post your response that includes the following:

Outline of the method of invoking your server and client programs
The server and client window screenshots for a sample service selected by the client
The source code of the programs

I would prefer to use select for multiplexing since it helps in better utilization of the resources. As an example, if there are 3 clients, it would check which clients are active and require service. It would provide service to the clients which require it rather than waiting for clients that do not require service. As per Stein (2001), it also helps to check whether an I/O operation would block prior to performing any operation. The select method is also less prone to errors compared to other methods....
