Abstract: In this paper we present what are, in our experience, the best practices in Peer-To-Peer(P2P) application development and how we combined them in a middleware platform called Mesmerizer. We explain how simulation is an integral part of the development process and not just an assessment tool. We then present our component-based event-driven framework for P2P application development, which can be used to execute multiple instances of the same application in a strictly controlled manner over an emulated network layer for simulation/testing, or a single application in a concurrent environment for deployment purpose. We highlight modeling aspects that are of critical importance for designing and testing P2P applications, e.g. the emulation of Network Address Translation and bandwidth dynamics. We show how our simulator scales when emulating low-level bandwidth characteristics of…

PeerNet helps broadband operators to minimize network traffic by making better use of the existing infrastructure. Large and popular content files are temporarily stored and distributed from local P2P-caches in the access networks, reducing peak traffic loads on weak links further up in the network. Product features: Content type agnostic. Dynamic traffic detection; Caching content with largest network traffic impact. Fault tolerant: P2P caching nodes can fail without damaging QoS. Cost efficient: Caching on inexpensive consumer grade hardware. Diagram 2. Decrease in link load from using locality aware P2P. (Source: H. Xie, A.
