Peer-to-peer (P2P) file sharing has become increasingly popular, accounting for as much as 70% of Internet traffic by some estimates. Recently, we have been witnessing the emergence of a new class of popular P2P applications, namely, P2P audio and video streaming. While traditional P2P file distribution applications target elastic data transfers, P2P streaming focuses on the efficient delivery ...

The Peer-to-Peer (P2P) architectures that are most prevalent in today's Internet are decentralized and unstructured. As the peers participating in unstructured networks interconnect randomly, they rely on flooding query messages to discover objects of interest and thus introduce remarkable network traffic. Empirical measurement studies indicate that the peers in P2P networks have similar prefer...

Peer-to-Peer (P2P) can support service for lots of end users with little hardware investment, which suits for the efforts to lower down the service cost for Multiplayer Online Games (MOG). In this paper, we introduce PKTown, a P2P middleware inserted into Star Craft and the network layer. PKTown captures all packets generated by Star Craft. Application Layer Multicast (ALM) is a popular techniq...

Modeling peer-to-peer (P2P) networks is a challenge for P2P researchers. In this paper, we provide a detailed analysis of large-scale hybrid P2P overlay network topology, using Gnutella as a case study. First, we re-examine the power-law distributions of the Gnutella network discovered by previous researchers. Our results show that the current Gnutella network deviates from the earlier power-la...

The Peer-to-Peer (P2P) paradigm provides an alternative design approach for distributed systems, which relaxes the requirement for dedicated service providers as it is the case in client-server systems. The P2P approach explores the potential to create distributed systems based on the resources and the services that can be provided by any end-point device connected to a common communication med...

As Peer-to-Peer (P2P) systems are widely deployed in the Internet, P2P traffic control becomes a challenge for Internet Service Providers (ISPs) and P2P system vendors. Some recent works consider the interaction between ISPs and P2P systems and propose ISP-friendly P2P traffic control mechanisms for reducing cross-ISP traffic. In this paper, we consider another fundamental problem: the interact...

This paper presents RING, a novel peer-to-peer (P2P) voice communicating system on mobile ad hoc network (MANET). RING proposes a ring overlay, a set of protocols, and an implementation enabling the delivery voice among peers without connecting to Internet. The logical overlay is proximal to the physical topology based on cross-layer scheme, which detects the network dynamics and peer movement ...
