Abstract:
The scalability and efficiency of P2P systems are
determined largely by two factors: the degree of matching
between the P2P overlay and its underlying physical network, and
the efficiency ofthe P2P application routing scheme. Most current
P2P systems address one or the other but not both in an
integrated manner. This paper proposes PIPPON, a two-layer
architecture to address these performance issues. At the overlay
network layer, the paper proposes a simple but effective Geo-
LPM/Geo-Partitioning scheme for constructing overlay that
mirrors the physical Internet. At the application routing layer, the
paper introduces a dynamic Key Tree that is built on the
optimized overlay to rout P2P messages efficiently. Simulation
results indicate that PIPPON is scalable and efficient, and holds
promise as a platform for large scale P2P applications.
