This document outlines an assignment for a Modern Networks course to design, implement, and test graphical Java and C# applications that can communicate over TCP and UDP like the netcat utility. Students must demonstrate their applications can: connect between programming languages over TCP and UDP; and optionally connect to other applications like web servers. A report is due January 15th documenting the virtual demo, design, implementation, testing, references, and appendices. This assignment aims to help students understand distributed computing applications using TCP and UDP in mobile and fixed contexts.

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).

4. 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.

5. • 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
15th January, 2017.
Your report should include the following sections:
1. Virtual Demo
2. Design
3. Implementation
4. Test
5. References
6. Appendices
Please note that the work you produce must be your own and
you may be asked
