Abstract — in a typical overlay network for routing or content sharing, each node must select a fixed number of immediate overlay neighbors for routing traffic or content queries a selfish node entering such a network would select neighbors so as to minimize the weighted sum of expected access costs to all its destinations. Overlay and p2p networks unstructured networks (similar to kazaa) overlay networks can result in really bad application. Skype – an example overlay peer-to-peer voip – developed by kazaa in 2003, acquired by microsoft in 2011 for us$ 85 billions – 34% of the call market share, 50 million concurrent online. Understanding kazaa article nevertheless, because kazaa is proprietary and uses encryption, little is understood about kazaa's overlay structure and dynamics, its messaging protocol, and its . The kazaa overlay: a measurement study more by virgil pruteanu both in terms of number of participating users and in traffic volume, kazaa is one of the most important applications in the internet today.
However, largely because kazaa is a proprietary protocol which encrypts its signalling messages, little has been known to date about the speci¯cs of kazaa's overlay, the maintenance of the overlay, and the kazaa signalling protocol. From kazaa to skype by the year 2002, niklas zennstrom and janus friis not only invented kazaa, but also entered the internet telephony market known as voice over internet protocol (voip) with their new service, skype. 13 p2p file sharing ualice runs p2p client application on her notebook computer uintermittently connects to internet gets new ip address for each connection uregisters her conten.

Two groups of clients: client and overlay emule, kazaa pure equipotent peers, all peers have equal amount of power what are peer-to-peer networks what is a . Nevertheless, because kazaa is proprietary and uses encryption, little is understood about kazaa’s overlay structure and dynamics, its messaging protocol, and its index management we have built two measurement apparatus- the kazaa sniffing platform and the kazaa probing tool- to unravel many of the mysteries behind kazaa.
