Network and service co-management addressing QoE and optimised resource allocation

The emergence of new technologies and services generates a situation in which an operator agonizes to manage uniformly and efficiently a complex network environment consisting of a number of underlying heterogeneous networks and a plethora of services with variant requirements. The network and service co-management of such a chaotic environment is a very intricate task which requires a notion of automation, harmonization and efficiency not foreseen by the current management frameworks. In this direction, the proposed policy translation framework aims at simplifying the network, as well as the service management by automatically translating the high level business goal imposed by the operator into low level enforceable policies customised to the peculiarities of each heterogeneous technology and service. In contrast to other similar studies, the proposed framework succeeds in comanaging network and services by using a set of policy templates, which constrains the policy translation process to only meaningful translations, by classifying the business goals based on KPIs, and by facilitating ontologies and ontological rules to all steps of policy translation.
