The journal "Peer-to-Peer Networking and Applications" aims to disseminate cutting-edge research and development results in this rapidly evolving field, facilitate the deployment of P2P networks and applications, and bring together the academic and industry communities to foster interaction that stimulates further research interest and activities, leading to new P2P applications and services. This journal covers not only research topics related to network and communication theory but also considers the standardization, economic, and engineering aspects of P2P technology, as well as their impacts on software engineering, computer engineering, network communication, and security. It serves as a forum for addressing the technical issues arising from file sharing and media streaming applications and includes state-of-the-art technologies in the field of P2P security. "Peer-to-Peer Networking and Applications" regularly publishes papers, tutorials, review articles, case studies, and letters from the research, development, and standardization communities. Papers addressing issues related to systems, applications, and services are encouraged.
