The paper reports on in-depth measurements and analysis of Gnutella signaling traffic collected at the Blekinge Institute of Technology (BIT), Karlskrona, Sweden. The measurements are based on a week-long packet trace collected with help of the well-known tcpdump application. Furthermore, a novel approach has been used to measure and analyze Gnutella signaling traffic. Associated with this, a d...

This paper describes our Gnutella compatible P2P system Gridella which is based on the P-Grid approach. P-Grid has several advantages over the standard Gnutella infrastructure, for example, that probabilistic estimates can be given for successful search requests and that it scales gracefully in the total number of nodes and data items. Gridella is designed for interoperability with Gnutella and...

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...

Modeling peer-to-peer (P2P) networks is a challenge for P2P researchers. It is the key to provide insight into the nature of the underlying system and building a successful model able to generate realistic topologies for simulation purpose. In this paper, we provide a detailed analysis of large-scale P2P network topology, using Gnutella as a case study. First, we re-examine the power-law distri...

Gnutella is a classical Peer-to-Peer network designed for file-sharing. The absence of pure servers is one of its main properties, given that every Gnutella host is client and host in one. It uses the resources of the participants to distribute content, e.g. mp3 compressed audio files, and shares the processing capacity to provide the routing and searching capabilities for the network. In this ...

The paper is focused on signaling traffic between Gnutella peers that implement the latest Gnutella protocol specifications (v0.6). In particular, we provide analytically tractable statistical models at session level, message level and IP datagram level for traffic crossing a Gnutella ultrapeer at Blekinge Institute of Technology (BTH) in Karlskrona, Sweden. To the best of our knowledge this is...

In the past few years much attention is given to an information exchange framework called Peer-to-Peer (P2P). This paper focuses on the Gnutella project as a successful example of decentralized P2P network. The author gives an overview of original and present Gnutella network architecture, makes the detailed description of messages exchange within the network, provides the reader with own exper...
