Project Description
This project requires students to implement a concurrent (multi-threaded) server for use in a client-server configuration to examine, analyze, and study the effects a concurrent server has on the efficiency (average turn-around time) of processing client requests.
Instructions
Students may refer to this Java ServerSocket TutorialLinks to an external site. and Running System Commands TutorialLinks to an external site. to help them create the server and client programs. Students must demonstrate their client and server programs, as well as collect data, using the provided Course Servers. Students should refer to the Accessing the Course Servers page for instructions on connecting to and using the two (2) Course Servers.
Create two (2) programs: 1) a concurrent (multi-threaded) server that accepts requests from clients, and 2) a multi-threaded client capable of spawning numerous client sessions that connect to the server The server and client programs must connect to the same network address and port The concurrent (multi-threaded) server should spawn a new server instance for each client request (in parallel) The concurrent (multi-threaded) server must support the following client requests: Date and Time - the date and time on the server Uptime - how long the server has been running since last boot-up Memory Use - the current memory usage on the server Netstat - lists network connections on the server Current Users - list of users currently connected to the server Running Processes - list of programs currently running on the server Create a multi-threaded client that transmits requests to the server on a specified network port The client program must be able to spawn multiple client sessions When the server program is launched, the server should Listen for client requests on the specified network address and port When a client request is received, the server should Spawn a new server instance to handle the request Determine which operation is being requested Perform the requested operation and collect the resulting output Reply to the client request with the output from the operation performed Destroy the server instance Perform any necessary clean up activities When the client program is launched, the client should Request the network address and port to which to connect Request the operation to request (refer to the list above) Request how many client requests to generate (1, 5, 10, 15, 20, 25 and 100) Collect the following data Turn-around Time (elapsed time) for each client request The time required for the client request to travel to the server, be processed by the server, and return to the client Total Turn-around Time (sum of the turn-around times for all the client requests) Average Turn-around Time (Total Turn-around Time divided by the number client requests) Deliverables
Program (50 points)
The source code, as well as any other software required, of the client and server programs.
Demonstration (50 points)
Teams will demonstrate the operations of their client and server programs to the professor in one of the School of Computing labs.
Report (50 points)
The report must contain a minimum of 1,000 words (not counting the Title Page). The report must contain the following sections (at a minimum):
Title Page (must include the following at a minimum, in some order): Title of the assignment (i.e., Concurrent Socket Server) Names of two (2) students Name of the class (i.e., CNT4504 - Computer Networks & Distributed Processing) Professor's Name Introduction Describe the purpose of the project in your own words Describe the goals of the project in your own words Introduce readers to what they will find in the remaining sections of the paper Client-Server Setup and Configuration Describe the design of the Client and Server programs Discuss the design decisions that were made Explain the basic operation of the Client and Server programs Testing and Data Collection Explain how the concurrent server was tested List and explain the data collected Provide at least one (1) chart or graph for the data collected for each of the six (6) operations Include the charts or graphs created for the Iterative Socket Server assignment Data Analysis Answer the following questions: What affect, if any, does increasing the number of clients have on the Turn-around Time for individual clients? What affect, if any, does increasing the number of clients have on the Average Turn-around Time? How do the Average Turn-around Time results contrast between the iterative server and the concurrent server? In which situation(s) might you want to use an iterative server? In which situation(s) might you want to use a concurrent server? Conclusion Explain the conclusion(s) you can draw from your data analysis Lessons Learned List any lessons you learned during the Concurrent Server assignment Some examples may inclue Writing the Client and Server programs Having a program execute Linux commands Collecting data Problems you had to overcome
