Content-aware networking in virtualised environments for optimised resource exploitation

Abstract : Today, the heterogeneity of current networking infrastructures, along with the lack of interoperability in terms of architectures and frameworks for adapting content to the various users’ contexts, prevent prosumers to deliver high QoE over different platforms and under diversified contexts. Consequently, the objective of this PhD thesis is to study, design, and develop a novel architecture capable to offer guaranteed QoS/QoE by efficiently exploiting the available resources and by dynamically adapting the network performance across the various Service, Network and User environments. To this end, the proposed architecture is based on (1) a distributed management framework that exploits Content Aware Network (CAN) mechanisms – on top of the Internet Protocol (IP) – for identifying content in transit and mapping its QoS/QoE requirements into specific network characteristics, and on (2) a network resource allocation mechanism for adapting the intra-domain resources to the requested QoS/QoE. A prototype Media-Aware Network Element (MANE) has been achieved, offering content type recognition and content-based routing/forwarding as a matter of guaranteed QoS/QoE provision in an end-to-end approach. Furthermore, it proposes a synergetic management system capable to orchestrate cross-layer optimization processes for service differentiation/classification, towards efficient resource exploitation. The validity of the proposed architecture is verified through a large number of experiments conducted using physical and virtual infrastructures. A large-scale test-bed conforming to the architectural design specifications was deployed for validating the proposed approach.
