A framework for P2P application development

Although Peer-to-Peer (P2P) computing has become increasingly popular over recent years, there still exist only a very small number of application domains that have exploited it on a large scale. This can be attributed to a number of reasons including the rapid evolution of P2P technologies, coupled with their often-complex nature. This paper describes an implemented abstraction framework that seeks to aid developers in building P2P applications. A selection of example P2P applications that have been developed using this framework are also presented

A Configurable Overlay Network Architecture

The application area of peer-to-peer (P2P) networks has grown in the last years. In a recent work the authors introduced a peer-to-peer overlay network based on the super peer model. In order to implement this overlay network the development of core P2P functions is required. These functions include peer organization, identification, message routing and fault tolerance among others. Different P2P frameworks were considered including JXTA and JGroups. In general, these frameworks provide a set of basic functionalities to facilitate P2P application development. However, they require extensive internal modifications for developing our P2P, because they already define the basic building blocks without the required flexibility. This paper introduces a configurable overlay network architecture for the development of core P2P functions. The architecture is based on the processing of messages, events and states. Thus, it is possible to translate a protocol definition based on a Finite State Machine into this architecture. On the other hand, a dynamic behavior definition is supported in order to introduce flexibility. Both features are suitable to implement a P2P overlay network.Sociedad Argentina de Informática e Investigación Operativ

A programmable structured peer-to-peer overlay

Structured peer-to-peer (P2P) overlay are scalable, robust and selforganizing in nature, and provide a promising platform for a range of largescal distributed applications. Applications proposed to date utilize a similar key-based routing service but "re-invent the wheel" by deploying their own dedicated structured P2P overlay network. This is highly inefficient and results in a significant duplication of work in terms of development, deployment and maintenance of the overlays. To address this problem, we propose a PROgrammable STructured P2P infrastructure (PROST), which allows the dynamic and incremental deployment of multiple applications over a single structured P2P overlay. In this paper, we outline the PROST architecture and discuss the implementation of our prototype

PROST: A programmable structured peer-to-peer overlay network

We present the idea of a programmable structured P2P architecture. Our proposed system allows the key-based routing infrastructure, which is common to all structured P2P overlays, to be shared by multiple applications. Furthermore, our architecture allows the dynamic and on-demand deployment of new applications and services on top of the shared routing layer
