Self-adaptation can be achieved by autonomic management of facets of a system's constituent components. This paper reports on a generic autonomic management framework and on its application to a key-based routing protocol as used in the peer-to-peer overlay Chord. The framework implements generic components of the autonomic management cycle. In the work reported here it was used to build a manager...
In order to inspire players of P2P MMOG to provide resources proactively, this paper presents a contribution level based incentive mechanism. Firstly, according to the resource consumption of the player nodes, the mechanism calculates the players' contribute score by a quantitative method of definite integral. Then, the contribute score is mapped into the contribute level with the sample data of the...
Internet users consume a large volume of rich media, and the consumption is increasing dramatically with the pervasiveness of network. BitTorrent has been well accepted as a solution to large-scale content distribution without requiring major infrastructure investment. However, it has not taken into account the link optimization across networks, causing heavy traffic across networks. This limitation...
In order to achieve the access of massive high-dimensional data on P2P network efficiently, we present a distributed similarity retrieval system named R-Chord using modified iDistance based on relative position code (RPCID). RPCID calculates the lower bound distance between the query point and the data point using relative position code (RPC). RPC is a data object encoding method based on spatial...
Peer-to-Peer (P2P) media streaming applications are increasingly popular on the Internet and offer a wide variety of media content, attracting potentially millions of viewers simultaneously. However, much content is duplicated, synchronously and asynchronously: popular Hollywood movies are often offered by many different on-demand streaming service providers; live streaming service providers distribute...
The searching mechanism of Gnutella in unstructured peer-to-peer network and its working principle are introduced. By analyzing its poor scalability problem, this paper proposes an improvement strategy based on dynamic topology regularization. The simulation results show that the strategy can effectively reduce the resource consumption of network and optimize the load-balancing among peers, and then...
