Abstract
In recent years, the growth of the Internet and the emergence of new network services contributed to the development of various architectures for distributed computing. In this context, P2P technology has fostered the interest of the scientific community due to its features and innovative characteristies. One of the factors responsible for this popularity is coming from consumer applications and file sharing. This service also occurs in a significant way into networks of smaller scope (e.g. LANs), where features present in the workstations are often wasted while corporations invest heavily in infrastructure to provide this particular service. A possible alternative in the face of this scenario is the adaptation of some concepts of P2P paradigm to the local network infrastructure. However, there are few efforts to explore the potential of communication peer-to-peer coupled with the patterns and advantages available in LANs. Due to its distributed nature, conventional P2P approaches adopted this system mainly in long distance (MANs and WANs) to overlay structure formation. However, these aspects do not make use of some techniques and features of P2P networks smaller. These factors motivated the proposal of LP2P-Local Peer-to-Peer-Protocol- a distributed communications platform that applies technology in P2P file sharing on local networks.
