Server

Contains two threads, UDP Server and Application Server.

ApplicationServer

Application server is the server that communicates with the client and handles the task. Upon receiving a request, calls the UDPServer:broadcast(String) to send a broadcast message to all services nearby. After the timeout returns the best address available.

UDPServer

UDPServer is the server that manages all services. It calls all services with a broadcast message, and saves their responses to a map. For each request generates a unique code corresponding to the client. Then waits until the timeout. After that finds the service with the lowest load and returns it's Server Response.
