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)
A new era in telecommunications is emerging. Virtualised 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 virtualised(More)
The purpose of autonomic networking is to manage the business and technical complexity of networked components and systems. However, the lack of a common lingua franca makes it impossible to use vendor-specific network management data to ascertain the state of the network at any given time. Furthermore, the tools used to analyze management data, which(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)
Network functions virtualization (NFV) continues to gain attention as a paradigm shift in the way telecommunications services are deployed and managed. By separating network function from traditional middleboxes, NFV is expected to lead to reduced capital expenditure and operating expenditure, and to more agile services. However, one of the main challenges(More)

The policy continuum is a fundamental component of any policy-based management implementation for autonomic networking, but as of yet has no formal operational semantics. We propose a(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)
