Welcometothe11thInternationalConferenceonTelecommunications(ICT2004)ho- ed by the city of Fortaleza (Brazil). As with other ICT events in the past, this professional meeting continues to be highly competitive and very well perceived by the international networking community, - tracting excellent contributions and active participation. This year, a total of 430 papers from 36 countries were submitted, from which 188 were accepted. Each paper was - viewed by several members of the ICT2004 Technical Program Committee. We were very pleased to receive a large percentage of top-quality contributions. Thetopicsofsubmittedpaperscoveredawidespectrumfromphotonictechniques,signal processing,cellularnetworks,andwirelessnetworks,toadhocnetworks.Webelievethe ICT2004papersofferawiderangeofsolutionstokeyproblemsintelecommunications, and describe challenging avenues for industrial research and development. In addition to the conference regular sessions, seven tutorials and a workshop were organized.Thetutorialsfocusedonspecialtopicsdealingwithnext-generationnetworks. The workshop focused on particular problems and solutions in heavily distributed and shareable environments. We would like to thank the ICT 2004 Technical Program Committee members and referees. Without their support, the creation of such a broad conference program would not be possible. We also thank all the authors who made a particular effort to contribute to ICT2004. We truly believe that due to all these efforts the ?nal conference program consisted of top-quality contributions. We are also indebted to many individuals and organizations that made this conference possible. In particular, we would like to thank the members of the ICT2004 Organizing Committee for their help in all aspects of the organization of this professional meeting.

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.

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. TheICN2005programcoveredavarietyofresearchtopicsthatareofcurrent interest,startingwithGridnetworks,multicasting,TCPoptimizations,QoSand security, emergency services, and network resiliency. 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 standardization.
