User Requirements (0) : The real user requirements that should be taken into account during the early phase of system design can be classified according to various perspectives and metrics, including durability, fault-tolerance and manageability. First, the user should be capable of maintaining a persistent connection to servers of interest. The model of peer-to-peer systems, although criticized for its business potential, has highly been adopted by the Internet community, due to the provision of a high degree of connectivity in a transparent fashion, even in the presence of failures. Users can always retrieve data regardless of the server location, whilst queries are optimized to fetch the nearest replica, exploiting locality and minimizing the necessary resources. Local loop unbundling aims at fast, always-on Internet access. These efforts have their counterparts in the mobile industry via the integration of Wireless LANs and 3G systems. The underlying objective is to combine a cheep, flexible, easily deployed but untrustworthy technology with a stable, resilient infrastructure. Users registered with a 4G provider would require that they be always connected enjoying an acceptable level of quality of service, while roaming among diverse systems including direct video. Thus, the issue have been split into: -Requirements on connectivity -Requirements on servive provision -Requirements on adaptibility and reconfigurability

Research agenda

In this section we identify the key research challenges in the future software systems enabling seamless service provisioning in heterogeneous, dynamically varying computing and communication environments. The division is not orthogonal; same or similar research topics and issues appear in more than one research challenges. We have divided the research space into the areas of:

• Adaptable Service Architectures
• Efficient and “always on” connectivity
• Application architectures for the support of Reconfigurability and Adaptability
• Generic Requirements & System Concepts
• System Integration
