Trends towards Next Generation Internet

In recent years we can witness a new wave of activities and projects to explore different paths towards Next Generation Internet. After the decade where the Internet Protocol becomes mainstream in communication networks integrating and carrying all new types of services with increasing traffic volume and complexity, there are rising concerns whether the aging Internet protocol architecture with its underlying legacy routing algorithms, control and security mechanisms would soon collapse under the load of new applications and the rapid change of traffic patterns and service generation paradigms in the next decade. In the talk we will focus on trends and evolution paths towards the Next Generation Network. The talk will discuss these trends together with issues of system performance and stochastic scalability, which are current topics of intensive research. These issues are crucial to dimension networks and applications, both from network provider and equipment manufacturer viewpoints. Some observations on future services will commence the talk. It will discuss the notion of Multi-Network Services, i.e. the paradigm shift from a network-centric view to a applicationcentric view. In the current existence of several wireless and wireline networks (PSTN, UMTS, WiMAX, etc.) users of different networks can install service-enabling software and start a new type of service in a short time scale and in a very dynamic way (e.g. VoIP platforms like Skype, software distribution schemes like Bittorrent, etc.). Those services are multi-networks services, which correspond to the term of Edge-based Intelligence.
