—Network function virtualization has received attention from both academia and industry as an important shift in the deployment of telecommunication networks and services. It is being proposed as a path towards cost efficiency, reduced time-to-markets, and enhanced innovativeness in telecommunication service provisioning. However, efficiently running(More)
This paper describes an approach for application specific conflict prevention based on model-driven refinement of policies prior to deployment. Central to the approach is an algorithm for the retrieval of application-specific data from an information model relating to the subject and targets of a given policy. This algorithm facilitates the linkage of(More)
— The increase in complexity of network management systems and a consequent lack of association to business requirements has driven the need for autonomic communications. By integrating context information, autonomic computing can provide more efficient means to counter technical problems found in complex network systems and at the same time address(More)
This paper presents an approach to provisioning network services in an autonomic network, using virtualised routers as an enabler. The approach provides business users a method of describing the requirements and behaviour of a set of network services using policies, while abstracting the users from complicated network configuration tasks. It then dimensions(More)
Networks are becoming service-aware implying that all relevant business goals pertaining to a service are fulfilled, and also the network resources are used optimally. Future Internet Networks (FIN) have time varying topology (e.g. such networks are envisaged in Autonomic Internet [1], FIND program [2], GENI program [3], FIRE program [4], Ambient Networks(More)
—A new era in telecommunications is emerging. Vir-tualised networking functions and resources will offer network operators a way to shift the balance of expenditure from capital to operational, opening up networks to new and innovative services. This paper introduces the concept of Edge-as-a-Service (EaaS), a means of harnessing the flexibility of(More)
The AUTOI project is creating a virtual communication resource overlay with autonomic characteristics to adapt the services and resources offered to meet changing user needs, business goals, and environmental conditions. Self-knowledge enables the network to reconfigure itself in the face of change to adapt its services according to business goals. The(More)
