Abstract

The diffusion of ultra-broadband (in terms of high bandwidth and low latency) connection, IT hardware advances, and growing availability of open-source software are causing a paradigm shift in the world of network architectures. In the last years, the number of devices and smart-objects connected to the network has grown exponentially and the so-called "machine intelligence'' has become part of the life-cycle of industries, agriculture, smart cities, and eventually public institutions. In this context, the initiative to integrate heterogeneous networks, including wired/wireless networks and smart-objects, from both the service management and control viewpoints is considered a critical aspect of Future Networks. The effect of all these drivers is the so-called "Softwarization" of telco infrastructures, where the approach to this integration is through the deployment of a flexible and programmable network infrastructure supporting software-driven network features that can be instantiated on-demand. These instantiations will be addressing the changing service requirements and resource constraints, yet be scalable across multiple services and multiple domains, can maintain QoS for end-users of a service, and that provide a level of isolation and security from one service to another. Research and development activities are currently clearly focused on several concepts such as programmable networks, network virtualisation, open interfaces and platforms, and increasing the degree of intelligence inside the network. The next generation of Software Defined Infrastructures needs to move from being merely Defined by software to be Driven by software and must be capable of supporting a multitude of players that exploit an environment in which services are dynamically deployed and quickly adapt over a heterogeneous physical infrastructure, according to chaining requirements. One of the main challenges includes the design and the implementation of specific mechanisms for run-time orchestration of logical resources in wired environments. In addition to mechanisms for controlling virtual resources in Software Defined Infrastructures, another challenge includes the design and implementation of specific algorithms for the efficient mapping of virtual resources onto physical resources. This thesis shows how network architectures based on open network features and resources abstraction offers innovative solutions addressing some of the challenges of Future Networks.
