• Create two (2) programs: 1) an iterative (single-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 iterative (single-threaded) server should handle one client request at a time (serially)
  • The Java ServerSocket object caches client requests automatically
• The iterative (single-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
    • 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
  • Perform any necessary clean up activities
  • Go back to listening for client requests
• 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 and 25)
  • 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)
