CALL FOR PAPERS JOURNAL OF NETWORK AND SYSTEMS MANAGEMENT http://www.cstp.umkc.edu/jnsm/ Special Issue on Peer-to-Peer Technologies in Network and Service Management One of the most interesting and promising technologies of the last five years is the Peer-to-Peer (P2P) technology. This technology allows users to voluntarily share computer resources such as storage space, processing power, and bandwidth. An important characteristic of P2P systems is that there is little or no central control, and each system can act as a client as well as a server. Initially, P2P systems were used for file-sharing purposes; examples of such systems are Kazaa and Bittorrent. Nowadays, P2P technologies are also used for many other kinds of applications, including VoIP (Skype), video distribution (GhostShare), and decentralized auctions (PeerMart). From a management perspective, P2P systems pose completely different challenges than traditional client-server systems. P2P systems include hardly any centralized management components and most distributed management functions are performed in an automatic way; examples of such functions include resource discovery, security, and NAT traversal. From a management perspective, P2P technologies are also interesting to manage traditional client-server application. Compared to traditional manager-agent technologies, the promise of P2P technologies is better scalability, improved reliability, and lower operational costs. This special issue of Journal of Network and Systems Management will focus on the management of P2P systems and the use of P2P technologies for managing traditional systems. Submissions may span a broad range of topics, including: • P2P-based management architectures and protocols • Distributed control and management in P2P systems • Accounting and payment in P2P environments • Security and trust management for P2P systems • (identification, authentication, reputation, auditing) • Performance, scalability, and reliability of P2P systems • (bandwidth, CPU load, memory usage) • Detection and analysis of P2P traffic • Impact of data retention legislation for P2P systems • Case studies and measurements Authors are invited to submit high quality and unpublished papers that are not under review in any other conference or journal. Submissions should be in single-column PDF format through the JEMS system (https://submissoes.sbc.org.br/jnsm). Paper preparation instructions can be found in any copy of the Journal, or by visiting the JNSM Web site at http://www.cstp.umkc.edu/jnsm/.
