Routing algorithms in Peer-to-Peer (P2P) networks
Routing algorithms in P2P networks determine how data packets are routed between nodes. Common routing algorithms include flooding, random walks, and greedy routing. The goal of these algorithms is to balance efficiency, scalability, and resilience in decentralized networks.
- Flooding:
- This simple algorithm involves a peer forwarding a query to all its neighbors. Each neighbor repeats this process until the query reaches its destination or expires.
- While straightforward, flooding can lead to redundant traffic and scalability issues, especially in large networks.
- Random Walks:
- Peers select random neighbors to forward queries, repeating this process until the target is found.
- Random walks are decentralized but may be inefficient for large networks and can take longer to locate resources.
- Distributed Hash Tables (DHTs):
- DHTs are structured routing algorithms that use a distributed hash table to map keys to peers responsible for storing corresponding data.
- Examples include Chord, Kademlia, and Pastry. DHTs organize peers into a structured overlay network, providing efficient and scalable routing with logarithmic time complexity for resource location.
- Small-World Networks:
- Small-world routing algorithms aim to exploit the “small-world phenomenon,” where most nodes can be reached from any other node in a small number of hops.
- These algorithms combine local and global knowledge to efficiently route queries in a decentralized manner.
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.
