Modern Networks Assignment 1 - CSY2026 Finish Date: 15th January, 2017 – By e-submission by 23:59 Aims & Objectives To enable the student to understand and extend Distributed Computing applications, using the Java programming language and C# .NET utilising the Transmission Control Protocol (TCP) as well as User Datagram Protocol (UDP). Brief: The netcat command line utility allows arbitrary TCP and UDP connections to be established between two or more instances of the utility, or between the utility and other applications, and for them to exchange data. Two console based applications, written in both Java and C#, have much of the functionality used by netcat. These source code behind these applications are available to you to help with this assignment. These two applications allow each to act as a: • • • •

TCP server TCP client UDP server UDP client

Design, implement and test a graphical version of netcat in both Java and C# so that these applications can be used in the same way as the netcat command line utility (There is no need to design the GUI behind the Java and the C# GUI applications as they are available as two skeleton applications. You need to design, implement and test the code behind each application). As, a minimum, you need to demonstrate that your two applications can communicate with themselves and each as follows. • • • • • •

Java TCP Listener Java TCP Java UDP Listener Java UDP C# TCP Listener C# TCP C# UDP Listener C# UDP Java TCP Listener C# TCP C# UDP Listener TCP UDP

You may also wish to show your application(s) communicating with existing applications. For example, with a web server (when acting as a web browser) or a web browser (when acting as a web server). Deliverables A report is required to be submitted to TurnitIn by 23:59 on 15
