BSc: Distributed And Network Programming

Distributed and Network Programming

• Course name: Distributed and Network Programming
• Course number: XYZ
• Knowledge area: xxx

Course characteristics

Key concepts of the class

• Network programming concepts: Layered architecture, TCP and UDP sockets, multithreaded servers
• Distributed systems concepts: system architecture, inter-process communication, remote procedure calls, peer-to-peer systems, coordination, replication, and fault tolerance.

What is the purpose of this course?

Distributed and networked systems have become an integral part of our life, we use various applications such as chatting, online transactions, or cloud storage apps. All these popular applications are supported by an infrastructure (of servers) that is organized based on some concepts of distributed systems. The purpose of this course is to provide the students with the necessary concepts, models, and real-world problem-solving techniques of network programming and distributed systems.

Course Objectives Based on Bloom’s Taxonomy

What should a student remember at the end of the course?

By the end of the course, the students should be able to recognize and define

• Concepts of network programming
• Different distributed system architectures
• Various synchronization and coordination techniques
• Different consistency models and replication methods
• Approaches to achieve fault tolerance and security in distributed systems

What should a student be able to understand at the end of the course?

By the end of the course, the students should be able to describe and explain (with examples)

• Difference between different transport protocols, when and why one is preferred over another
• Difference between different distributed system architectures (centralized, decentralized, and hybrid)
• How a mutual exclusion is achieved between concurrent servers (centralized, distributed, token-ring, and decentralized)
• How a new leader is elected in peer-to-peer systems (bully, ring)
• How to achieve a consistent replicas across distributed systems (consistency models and protocols, content replication and placement)
• Some methods to achieve the fault tolerance in distributed systems

What should a student be able to apply at the end of the course?

By the end of the course, the students should be able to apply

• Building a custom application protocols on top of the existing transport protocols
• Writing multithreaded server and client apps with sockets
• Using RPC for inter-process communication: command execution, file transfer
• Building peer-to-peer systems with distributed protocol such as Chord
• Building fault-tolerant systems with failure detection and leader election
