70226 - Network Programming

Learning outcomes

At the end of the course the student should be able to understand the more common technologies used to design network applications and the most common protocols.

Course contents

The course will present the basic principles of design and implementation of network applications. The theoretical concepts presented will be applied in laboratory projects aimed at understanding the implementation of network application in today Internet.

The course will follow the so called "top-down" approach.

• Internet and computer networks: Internet, protocols, client-server architecture, protocol layers and service models.
• Protocol analysis: sniffing, collection of traffic traces, analysis and debug, use of the Wireshark protocol analyzer.
• Application layer: architectures, application level protocols (Web and HTTP, FTP, SMTP, POP3, IMAP, DNS), P2P architectures (BitTorrent), socket programming.
• Transport layer: services, multiplexing and demultiplexing, connectionless service, UDP protocol, reliable data transfer, connection-oriented communication, TCP protocol, congestion control.
• Basics of cybersecurity: authentication, authorization, digital signatures and certificates.
