The field of structured P2P systems has seen fast growth upon the
introduction of Distributed Hash Tables (DHTs) in the early 2000s.
The first proposals, including Chord, Pastry, Tapestry, were
gradually improved to cope with scalability, locality and security
issues. By utilizing the processing and bandwidth resources of end
users, the P2P approach enables high performance of data
distribution which is hard to achieve with traditional
client-server architectures. The P2P computing community is also
being actively utilized for software updates to the Internet,
P2PSIP VoIP, video-on-demand, and distributed backups. The recent
introduction of the identifier-locator split proposal for future
Internet architectures poses another important application for
DHTs, namely mapping between host permanent identity and changing
IP address. The growing complexity and scale of modern P2P systems
requires the introduction of hierarchy and intelligence in routing
of requests. Structured Peer-to-Peer Systems covers fundamental
issues in organization, optimization, and tradeoffs of present
large-scale structured P2P systems, as well as, provides
principles, analytical models, and simulation methods applicable in
designing future systems. Part I presents the state-of-the-art of
structured P2P systems, popular DHT topologies and protocols, and
the design challenges for efficient P2P network topology
organization, routing, scalability, and security. Part II shows
that local strategies with limited knowledge per peer provide the
highest scalability level subject to reasonable performance and
security constraints. Although the strategies are local, their
efficiency is due to elements of hierarchical organization, which
appear in many DHT designs that traditionally are considered as
flat ones. Part III describes methods to gradually enhance the
local view limit when a peer is capable to operate with larger
knowledge, still partial, about the entire system. These methods
were formed in the evolution of hierarchical organization from flat
DHT networks to hierarchical DHT architectures, look-ahead routing,
and topology-aware ranking. Part IV highlights some known P2P-based
experimental systems and commercial applications in the modern
Internet. The discussion clarifies the importance of P2P technology
for building present and future Internet systems.
