whitepaper QoS Routing for P2P Networking2008-01-01 Helsinki University of Technology
  "Peer-to-peer" concept is the core of today's Internet but it will become even greater factor in the future Internet. P2P-networks grow on their own by flooding and updating the information using peer-to-peer concept. The peers (storage and computing power) are used to make the routing and data-searching faster. This paper focuses to QoS routing and to P2P networking. Techniques like Resource Reservation (RSVP), Differential Services (DiffServ) and MultiProtocol Label Switching (MPLS) are briefly introduced.

whitepaper Towards Data Mining in Large and Fully Distributed Peer-to-Peer Overlay Networks2008-01-01 Vrije Universiteit
  The Internet, which is becoming a more and more dynamic, extremely heterogeneous network has recently became a platform for huge fully distributed peer-to-peer overlay networks containing millions of nodes typically for the purpose of information dissemination and file sharing. This paper targets the problem of analyzing data which are scattered over a such huge and dynamic set of nodes, where each node is storing possibly very little data but where the total amount of data is immense due to the large number of nodes. The paper presents distributed algorithms for effectively calculating basic statistics of data using the recently introduced newscast model of computation and the paper demonstrates how to implement basic data mining algorithms based on these techniques.

whitepaper Distributed Data Mining in Peer-to-Peer Networks2008-01-01 university of maryland
  Distributed data mining deals with the problem of data analysis in environments with distributed data, computing nodes, and users. Peer-to-peer computing is emerging as a new distributed computing paradigm for many novel applications that involve exchange of information among a large number of peers with little centralized coordination. Peer-to-peer file sharing, peer-to-peer electronic commerce, and peer-to-peer monitoring based on a network of sensors are some examples. This paper offers an overview of distributed data mining applications and algorithms for peer-to-peer environments. It describes both exact and approximate distributed data mining algorithms that work in a decentralized manner.

whitepaper P2P-Based Collaborative Spam Detection and Filtering2008-01-01 Universita degli Studi di Milano
  Spam is one of the major problems of today email systems. While many solutions have been proposed to automatically detect and filter spam, spammers are getting more and more technically sophisticated and aware of internal workings of anti-spam systems, finding ways to disguise their emails to get around the different controls that can be enforced. This paper proposes a decentralized privacy-preserving approach to spam filtering. The solution exploits robust digests to identify messages that are a slight variation of one another and a structured peer-to-peer architecture between mail servers to collaboratively share knowledge about spam.

whitepaper Performance Analysis of a Hybrid Media Streaming System2008-01-01 Purdue University
  Recent research efforts have demonstrated the promising potential of building cost-effective media streaming systems on top of Peer-to-Peer (P2P) networks. A P2P media streaming architecture can reach large size and streaming capacity that are difficult to achieve in conventional server-based streaming services. Hybrid streaming systems that combine the use of dedicated streaming servers and P2P networks were proposed to build on the advantages of both paradigms. However, the dynamics of such systems and the impact of various factors on system behaviors are not totally clear. This paper presents an analytical framework to quantitatively study the features of a hybrid media streaming model.

whitepaper GridCrypt: High Performance Symmetric Key Cryptography Using Enterprise Grids2008-01-01 University of Melbourne
  Today's cryptanalysis on symmetric key cryptography is encouraging the use of larger key sizes and complex algorithms to achieve an unbreakable state. However, this leads an increase in computational complexity. This has promoted many researchers to develop high-performance symmetric key cryptography schemes using approaches such as the use of high-end computing hardware. Peer-to-Peer (P2P) or enterprise grids are proven as one of the approaches for developing cost-effective high-end computing systems. By utilizing them, one can improve the performance of symmetric key cryptography through parallel execution. This approach makes it attractive for adoption by businesses to secure their documents. This paper proposes and develops an application for symmetric key cryptography using enterprise grid middleware called Alchemi.

whitepaper Verifying Data Integrity in Peer-to-Peer Media Streaming2008-01-01 Purdue University
  The paper studies data integrity verification in peer-to-peer media streaming for content distribution. Challenges include the timing constraint of streaming as well as the untrustworthiness of peers. The paper shows the inadequacy of existing data integrity verification protocols, and proposes Block-Oriented Probabilistic Verification (BOPV), an efficient protocol utilizing message digest and probabilistic verification. The paper then proposes Tree-based Forward Digest Protocol (TFDP) to further reduce the communication overhead. A comprehensive comparison is presented by comparing the performance of existing protocols and the protocols, with respect to overhead, security assurance level, and packet loss tolerance.

whitepaper Source Vs Data-Driven Approach for Live P2P Streaming2008-01-01 Laboratorie d'Informatique de Paris 6
  Live streaming applications are increasing on the Internet. These applications are delay sensitive and need group communication. Presently, protocols designed for this kind of communication do not rely on the classical client/server model used in the Internet but organize the receivers into an overlay network, where they are supposed to collaborate with each other following the peer-to-peer model. Live p2p streaming protocols can be classified in three different categories: source-driven, receiver-driven and data-driven protocols. Each of them manages the overlay differently. This paper compares them by simulation to specify what is the most appropriate approach for these protocols.

whitepaper A Peer-to-Peer On-Demand Streaming Service and Its Performance Evaluation2008-01-01 University of Massachusetts
  Providing on-demand video streaming service over the Internet is a challenging task. This paper proposes DirectStream, a directory based peer-to-peer video streaming service that efficiently and cost-effectively provides video on-demand service with VCR operation support. The paper analytically and experimentally examines the system performance, and show that the proposed scheme can significantly reduce the workload posed on the server, and that it scales extremely well as the popularity of the video increases even if participating clients behave non-cooperatively. The paper proposes a QoS parent selection algorithm to construct the appropriate peer-to-peer networks, and discuss how to provide continuous playback in the face of clients' early departures.

whitepaper Analysis of a Hybrid Architecture for Cost-Effective Streaming Media Distribution2008-01-01 Purdue University
  To distribute video and audio data in real-time streaming mode, both CDN (Content Distributed Network) based and peer-to-peer based architectures have been proposed. However, each architecture has its limitations. CDN servers are expensive to deploy and maintain. The storage space and out-bound bandwidth allocated to each media file are limited and incur a cost. Current solutions to lowering such cost usually compromise the media quality delivered. On the other hand, a peer-to-peer architecture needs a sufficient number of 'Seed' supplying peers to 'Jumpstart' the system. Compared with a CDN server, a peer offers very low out-bound bandwidth. Furthermore, it is not clear how to fairly determine the contribution of each supplying peer.
