Peer-to-Peer (P2P) gained a lot of interest these days and variety of P2P applications are increasing too. Among these all applications, P2P frameworks try to simplify the development process. In past, they provided some high level functions and had a static architecture dedicated to a network structure or topology. In present, complex applications have become more interesting. For instance, applications require communicating with numbers of different overlay networks, topologies and underlying networks. An open and flexible architecture would be interesting in such cases. Changes and updates of applications make them difficult to maintain. Extendible and pluggable architecture can reduce change and update costs which lead to reduce the maintenance costs. Thus, the need to a new generation of P2P frameworks to support these requirements is inevitable. In this paper, we propose a new extendable framework with a flexible architecture. This framework so-called TierPeer is based on three-tier model of client-server paradigm and OSI model of distributed system paradigm.
