Types of Peer-to-Peer (P2P) Networks
Below are the types of P2P Networks:
1. Pure P2P Networks
Also known as decentralized or true P2P networks, pure P2P networks operate without any central authority or dedicated infrastructure.
- Peers in these networks have equal privileges and responsibilities, and they directly communicate and share resources with each other.
- Examples include BitTorrent and Gnutella.
2. Hybrid P2P Networks
Hybrid P2P networks combine elements of both decentralized and centralized architectures.
- They typically include some central servers or super peers that coordinate network activities, manage resources, or provide additional services.
- Hybrid P2P networks aim to achieve a balance between decentralization and efficiency. Examples include Skype and eDonkey.
3. Overlay P2P Networks
Overlay P2P networks create a virtual network on top of an existing infrastructure, such as the internet.
- Peers in these networks establish direct connections with each other, forming an overlay structure that facilitates resource sharing and communication.
- Overlay P2P networks often employ distributed hash tables (DHTs) or other routing mechanisms to locate and retrieve resources efficiently. Examples include Chord and Kademlia.
4. Structured P2P Networks
Structured P2P networks organize peers into a specific topology or structure, such as a ring, tree, or mesh.
- Peers maintain routing tables or other data structures to facilitate efficient resource lookup and data retrieval.
- Structured P2P networks offer predictable performance and scalability but may require additional overhead for maintenance. Examples include CAN (Content Addressable Network) and Pastry.
5. Unstructured P2P Networks
In contrast to structured P2P networks, unstructured P2P networks do not impose any specific topology or organization on peers.
- Peers in these networks typically rely on flooding or random search algorithms to locate resources, resulting in lower efficiency but greater flexibility and simplicity.
- Examples include early versions of Gnutella and Freenet.
Peer-to-Peer (P2P) Architecture
Peer-to-peer (P2P) architecture is a decentralized computing model where network participants share resources directly with each other without the need for a centralized server. In a P2P network, each node acts as both a client and a server, enabling distributed sharing of files, data, and computing resources. This article provides a comprehensive overview of the P2P architecture, including its characteristics, benefits, types, key components, bootstrapping process, data management, routing algorithms, challenges, security techniques, and applications.
