As communications networks become increasingly dynamic, heterogeneous, less reliable, and larger in scale, it becomes difficult, if not impossible, to effectively manage these using traditional approaches that rely on human monitoring intervention ensure they operate within desired bounds. Researchers practitioners are pursuing the vision of autonomic network management, which we view as capability entities self-govern their behavior constraints business goals a whole seeks achieve. However,...

The continued movement towards converged networks changes the focus to building application services that enable customers move between different types of service providers based on their needs. Policy management becomes paramount for rapid deployment and these services. This paper presents concept a policy continuum discusses importance modeling natural languages in presence continuum, resulting novel architecture suitable autonomic computing

The focus of new service development continues to move from network services towards application services. This is driven by many factors, such as converged networks, ambient networks and seamless mobility. These other efforts enable customers one provider another based on the availability desired services, well metrics concerning their performance (e.g., reliability cost). In order rapid deployment these policy becomes paramount. paper presents first experiences with implementation...

Telecommunication companies with expensive networks may become the biggest beneficiaries of SDN; however, in contrast to traditional routers, development SDN controllers is driven by open-source projects involvement industry. Two prevalent are OpenDaylight and ONOS controllers. These advanced their - having gone through a number releases have been described as being useful for large use-cases. In this work, we compare evaluate these controllers, particular northbound interfaces, configuring...

We outline an approach to policy specification and analysis in which information model is used as the starting point for semi-automated generation of integrated suite languages, tools ontology. The includes separate domain-specific languages systems structure policies respectively, editors checkers these a baseline ontology that can be augmented with semantic support analyses processes. describe prototypical realisation approach, showing how are transformation conflict detection

The idea of virtualizing network functions is driven by recent advances in network-focused hardware. In 2012, several large telecommunication operators issued a call to action for Network Function Virtualization (NFV) <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> . underlying that every service currently delivered on proprietary, application specific hardware should be deliverable using virtual machines. This means routers, firewalls,...

Monitoring and management of modern telecommunication networks has become more challenging due to the explosion in scale data generated by network elements. Not only size network, number nodes, customers increased, but amount dimensionality coming from each managed element also increased. To support sophisticated monitoring strategies it is desirable forward as much trace possible into operators' operations systems (Operations Support Systems (OSSs)). In this paper a heuristic algorithm...

The development of three-dimensional aperiodic energy storage devices is in part impeded by the lack appropriate templates that can withstand thermal conditions required to deposit materials within their void space.

Network management has suffered from increases in business, system, and operational complexity. This been exacerbated by the heterogeneity data as well high quality requirements of multimedia services. Autonomic networking manages this growing complexity adding intelligence inside network nodes applications. While most autonomic applications simply use a control loop to monitor configure entities, our work is aimed at building self-governing that able fulfill current future means need...

Next generation networks, as well the future Internet, aim to provide context-sensitive business services that adapt changing user needs, goals, and environmental conditions.
