In this context, in order to provide SOA-based applications with high levels of QoS (quality of service), service providers may employ P2P (peer-to-peer) networks to bring applications closer to their consumers, overcoming slow backbone paths, network congestions and physical latencies. The ability to efficiently carry out service discovery activities is a key issue for effectively managing the QoS of SOA-based P2P applications. To this purpose, this paper introduces QSHARE, an approach for the QoS-enabled description and discovery of services in SOA-based P2P applications. The proposed approach introduces a novel peer architecture that makes use of QoS-enabled service descriptions and its effectiveness is shown within the context of a model-driven framework for managing the QoS of SOA-based P2P applications.}, keywords = {Computer networks, Enabling technologies, P2P applications, Quality of service}, isbn = {0769528791; 9780769528793}, issn = {15244547}, doi = {10.1109/WETICE.2007.4407144}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-51149106143\&partnerID=40\&md5=6e581af0df8d7f406326082475a8262d}, author = {Bocciarelli, P. and Andrea D{\textquoteright}Ambrogio and Angelaccio, M.} } @conference {Angelaccio200695, title = {A model-driven framework for managing the QoS of collaborative P2P service-based applications}, booktitle = {Proceedings of the Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises, WETICE}, year = {2006}, note = {cited By 6}, pages = {95-100}, abstract = {Distributed and collaborative applications are rapidly converging towards the adoption of a computing paradigm based on service-oriented architectures, according to which an application results from the composition of a set of services in execution on networked server hosts. In this context, a major challenge for collaborative businesses and application service providers is to provide services with high levels of QoS to geographically dislocated consumers. In order to enable better QoS, service providers may employ overlay networks to bring applications closer to their consumers, overcoming slow backbone paths, network congestions and physical latencies. This paper introduces a model-driven QoS management framework that provides both a standard (UML-based) notation to describe QoS-aware collaborative P2P service-based applications and a method for adaptive QoS management based on the automated building of performance models. {\textcopyright} 2006 IEEE.}, keywords = {Application service provider (ASP), Architectural design, Collaborative Applications, Collaborative businesses, Computing paradigms, Distributed computer systems, Enabling technologies, In order, Industry, Information services, International workshops, Model-driven, Network architecture, Network congestions, Overlay Networks (ON), performance modelling, QOS management, Service oriented architectures (SOAs), Service provider (SP), Service-based, Standards, Systems analysis, Telecommunication networks, Unified Modeling Language}, isbn = {0769526233; 9780769526232}, issn = {15244547}, doi = {10.1109/WETICE.2006.9}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-46449083466\&partnerID=40\&md5=9f8545baa48661a0597b49ba825a295a}, author = {Angelaccio, M. and Andrea D{\textquoteright}Ambrogio} }
