P2P Networks - Introduction

Peer-to-peer networks, AKA P2P networks, are networks of computer communicating without a central server. Peers are different from clients and servers in that clients and servers have different roles, whereas peers typically all have the same roles - each acting as both client of, and server to, other peers in the P2P network.

There are multiple P2P network topologies - such as unstructured P2P topologies, N-dimensional grid P2P topologies, tree P2P topologies, ring P2P topologies and my own - the polyring P2P topology. I introduce each of these topologies in this video.
