Thebeginningofthe21stcenturyiswitnessingadrivetotheconvergenceof?xed and mobile telecommunication networks and the increasing adoption of IP te- nologies for implementing seamless multimedia applications in next-generation networks. The IEEE International Workshop Series on IP Operations & M- agement (IPOM) is documenting this evolution by providing snapshots of the state of the art in the ?eld of operations and management in IP-based networks. The 5th IEEE International Workshop on IP Operations & Management (IPOM2005), devotedtothe O&MChallengesinNextGenerationServicesand Networks, was held in Barcelona, Spain, October 26 28, 2005. Here IPOM was one of the ?ve collocated events under the banner First International Week on ManagementonNetworksandServices(www.manweek2005.org), togetherwith the 16th IFIP/IEEE International Workshop on Distributed Systems: Ope- tionsandManagement(DSOM2005), the8thInternationalConferenceonM- agement of Multimedia Networks and Services (MMNS 2005), the 2005 Sym- siumonSelf-stabilizingSystems(SSS2005)andthe1stIEEE/IFIPInternational Workshop on Autonomic Grid Networking and Management (AGNM 2005). Thisbookcontainstheo?cialproceedingsofIPOM2005.Itfeatures21hi- quality papers grouped into seven technical sessions looking at O&M for VoIP, IMS and managed IP services, management of open interfaces, QoS and pricing in NGNs, autonomic communications, policy-based management, routing and topologies, routing and tools, as well as experiences from testbeds and trials. Additional papers presented in two short sessions are published separately. Wewouldliketothanktheauthorsforalltheire?orts, aswellasthemembers of the Technical ProgramCommittee, and the reviewers. Without their support the high-quality program of this event would not have been possible. We are also indebted to many individuals and organizations that made the conference possible (IEEE, IARIA, Fraunhofer Institute FOKUS, JEMS s drivers, and the Universitat Polit ecnica de Catalunya)."

The International Conference on Networking (ICN 2005) was the fourth conf- ence in its series aimed at stimulating technical exchange in the emerging and important ?eld of networking. On behalf of the International Advisory C- mittee, it is our great pleasure to welcome you to the proceedings of the 2005 event. Networking faces dramatic changes due to the customer-centric view, the venue of the next generation networks paradigm, the push from ubiquitous n- working, andthenewservicemodels.Despitelegacyproblems, whichresearchers and industry are still discovering and improving the state of the art, the ho- zon has revealed new challenges that some of the authors tackled through their submissions. InfactICN2005wasverywellperceivedbytheinternationalnetworkingc- munity. A total of 651 papers from more than 60 countries were submitted, from which 238 were accepted. Each paper was reviewed by several members of the Technical Program Committee. This year, the Advisory Committee revalidated various accepted papers after the reviews had been incorporated. We perceived a signi?cant improvement in the number of submissions and the quality of the submissions.

The Program Committee selected also three tutorials and invited speakers that addressed the latest - search results from the international industries and academia, and reports on ?ndings from mobile, satellite, and personal communications related to 3rd- and 4th-generation research projects and standardiz

The 1st Workshop on Service Assurance with Partial and Intermittent Resources (SAPIR 2004) was the first event in a series introducing the concept of pi-resources and bridging it with the emerging and important field of distributed and heavily shared resources. The topics concerning this event are driven by a paradigm shift occurring in the last decade in telecommunications and networking considering partial and intermittent resources (pi-resources). The Internet, converged networks, delay-tolerant networks, ad hoc networking, GRID-supporting networks, and satellite communications require a management paradigm shift that takes into account the partial and intermittent availability of resources, including infrastructure (networks, computing, and storage) and service components, in distributed and shared environments. A resource is called partial (p-resource) when only a subset of conditions for it to function to complete specification is met, yet it is still able to provide a (potentially degraded) service, while an intermittent or sporadic resource (i-resource) will be able to provide a service for limited and potentially unpredictable time intervals only. Partial and intermittent services are relevant in environments characterized by high volatility and fluctuation of available resources, such as those experienced in conjunction with component mobility or ad hoc networking, where the notion of traditional service guarantees is no longer applicable. Other characteristics, such as large transmission delays and storage mechanisms during the routing, require a rethinking of today's paradigms with regards to service assurance and how service guarantees are defined.

This book, AICON 2022, constitutes the post-conference proceedings of the 4th EAI International Conference on Artificial Intelligence for Communications and Networks, AICON 2022, held in Hiroshima, Japan, in November 30- December 1, 2022. The 9 full papers and 4 short papers were carefully reviewed and selected from 36 submissions. The papers detail research in the areas of AI and communication systems related to intelligent systems and computational intelligence for communication and networks. They are organized in topical sections on AI and networks; machine learning; and evolutionary computation.
