Client-Server-using-IPC

This is a C++ assignment that mimics client server interaction.

This is a client program that connects to a given server. The server defines a communication protocol, which the client has to implement by sending properly formulated messages over a communication pipe. The server hosts several electrocardiogram (ECG) data points of 15 patients suffering from various cardiac diseases. The client’s goal is to obtain these data points by sending properly-formatted messages that the server understands. In addition, the server can send raw files potentially in several segments. Obtained the above dataset from physionet.org.

This project was part of my operating systems class, and was recently moved to my public repo.

Server Specification

The server supports several functionalities. The client requests a certain functionality by sending the appropriate message to the server. Internally, the server will execute the correct corresponding functionality, prepare a reply message for the client, and send it back.

Connecting to the Server You will see the following in the server main function: FIFORequestChannel* control_channel = new FIFORequestChannel ("control", FIFORequestChannel::SERVER_SIDE); which sets up a communication channel over an OS-provided IPC mechanism called “named pipe”. Note that the first argument in the channel constructor is the name of the channel. To connect to this server, the client has to create an instance with the same name, but with CLIENT_SIDE as the second argument: FIFORequestChannel chan ("control", FIFORequestChannel::CLIENT_SIDE);

Flag Description

• p flag is the patient number
• t flag is for time
• e flag is for the ecg number (1 or 2)
• m flag is the buffer capacity
• f flag is for file transger
• c flag is for channel creation
