چکیده

Managing increasing traffic from Instant Messengers and P2P applications is becoming more important nowadays. We present an inkernel architecture of management gateway, namely kP2PADM, built upon open-source packages with several modifications and design techniques. First, the in-kernel design streamlines the data path through the gateway. Second, the dual-queue buffer eliminates head-of-line blocking for multiple connections. Third, a connection cache reduces useless reconnection attempts from the peers. Fourth, a fast-pass mechanism avoids slowing down the TCP transmission. The in-kernel design approximately doubles the throughput of the design in the user space. The internal benchmarks also analyze the impact of each function on performance. key words: P2P/IM management, gateway, in-kernel implementation

P2P Network Trust Management Survey

Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...

The OpenKnowledge Kernel

Web services are pieces of software that can be invoked via a standardized protocol. They can be combined via formalized taskflow languages. The OpenKnowledge system is a fully distributed system using P2P technology, that allows users to publish these taskflows, and programmers to register their web services or publish implementations of them, for the roles described in these workflows. Beside...
