Peer-to-Peer Networking with Pastry and Tapestry Protocols

Distributed systems power much of modern internet infrastructure, but how do decentralized nodes find each other and share data without a central server? This course introduces you to the core architecture of structured peer-to-peer (P2P) networks. You will transition from understanding basic network models to grasping the algorithms behind Distributed Hash Tables (DHTs). Through clear, written explanations and conceptual walkthroughs, you will learn how protocols like Chord, Pastry, and Tapestry handle routing, node joins, and fault tolerance. What you'll learn: - Understand the fundamental principles of peer-to-peer architectures and Distributed Hash Tables (DHTs). - Compare the lookup mechanics of Chord with the prefix-based routing of Pastry and Tapestry. - Analyze how proximity neighbor selection optimizes routing latency in decentralized systems. - Explore how nodes dynamically join, leave, and maintain routing tables in an active network. - Examine modern applications of these protocols in decentralized storage and content delivery. The course starts with foundational networking definitions and basic P2P concepts before diving deep into the algorithmic details of each protocol. You will explore step-by-step routing examples and finish with practical scenarios demonstrating how these systems scale. Designed for beginner software engineers, network students, and decentralized technology enthusiasts, this course requires no prior experience with peer-to-peer protocols.
