Brief description of the course unit:

Introduction to Network Protocol Stacks. General requirements, resource sharing, multiplexing, layered network architecture, program interfacing. ISO/OSI reference model, 5-layer model.

Direct Link Networks. System properties of physical media. Bandwidth, latency, trip-time concepts and “keeping the pipe” full. Nodes and links, link encoding, data frame protocols and error protection. Reliable transmissions and use of automatic repeat request protocols and sliding window algorithm.

Local Area Networks. Ethernet (IEEE 802.3), Wireless LAN (IEEE 802.11, IEEE 802.15), physical structures, access protocol and operational properties.

Packet Switching. Reliable vs. unreliable connections, datagrams, network switching, virtual circuits, store-and-forward concepts. LAN switches, routing algorithms. Unicast, multicast and broadcast concepts.

Internetworking. The Internet Protocol (IPv4) – service model, datagrams, addressing, host configuration and error reporting. Routing algorithms (distance vector, link state) and routing metrics. Concepts of sub-netting and classless routing.

End-to-End Protocols. Unreliable (UDP) and reliable (TCP) protocols, segment formats, connection establishment and termination, sliding window and adaptive retransmission.

Domain Naming and Hierarchies. The Domain Name System.

Embedded Systems Networks. Specific requirements and design issues of embedded systems networks: topologies, protocols, robustness, error handling. Synchronous and asynchronous protocols. Examples of embedded systems networks: I2C, SPI, CAN, LIN.

Coding of digital dataHamming codes, parity, CRC and IP checksums.

Network Security. Cryptographic algorithms: symmetric key, public key, message digest. Security services: privacy, authentication, integrity control, non-repudiation.
