The goal of this exercise is to implement a peer-to-peer system (consisting of one server and

several clients) for the transmission of arbitrary (binary) files. Client and server are supposed

to be developed in C under Linux. Transmission of data as well as exchange of control

information is conducted using TCP. Additionally, UDP is used for server discovery on the

network.

**The most important thing is to have comments explaining what each function does, detailed and understandable.

Functional overview:**

The peer-to-peer client is supposed to be able to provide one file for download as well as to

download one file from another client. The server shall act as a broker for the clients and

maintains a TCP connection to each of them in order to exchange status information. Each

client offers an UI that displays a list of provided files and allows selecting one file for

download. The download is performed directly between two clients.

**Feature requests:**

1) The server has to support up to ten clients.

2) The client’s UI shall allow displaying and refreshing the list of provided files. If a file

has been selected for download, the progress is presented to the user.

3) In order to download a file the client connects to the providing client using TCP’s

“active open??. The peer directly starts to send the file and the process stays invisible

to the user. At client side, the transmitted file is saved to disk.

4) Clients discover a server by sending a UDP multicast message.

**Implementation requests:**
