+Gnutella \cite{gnutellaurl} is a flooding broadcast file-sharing system which 
treats all nodes in the network functionally equivalent. Each peer tries to 
maintain 
 a small number of active connections to its neighbor. These peers are selected 
from a locally maintained host catcher list, which contains 
 the addresses of the neighbor peers. Gnutella uses a Breadt-First-Search (BFS) 
traversal with depth limit L, where L is the system-wide maximum TTL 
 of a message in hops. Every node receiving a query will forward the message to 
all of its neighbour nodes, unless the message has

+\section{YAPPERS}
+YAPPERS (Yet Another Peer-to-Peer System) \cite{ganesan02yappers} is hybrid 
peer-to-peer system. YAPPERS operates on top of an arbitrary overlay network 
+, such as Gnutella, while providing DHT-like search efficiency. Furthermore, 
in YAPPERS approach, many small DHTs are built instead 
+of one imposing DHT structure. YABBERS divides a large overlay network into 
many small neighborhoods. The data within each neighborhood is partiotioned 
among 
+other neighbors like a regular DHT. Lookup queries relies on forwarding 
mechanism, similar to Gnutella-style flooding, to traverse all the small 
+DHTs in the network. Specifically, within node's immediate neighborhood, 
YAPPERS behaves like a DHTs. When using extended lookup outside of immediate 
+neighborhood, YAPPERS behaves like Gnutella, but with more intelligence.
