A dynamic pricing algorithm for a network of virtual resources
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Restricted access - publisher's policyA service chain is a combination of network services (e.g. network address translation (NAT), a firewall, etc.) that are interconnected to support an application (e.g. video-on-demand). Building a service chain requires a ... -
A path generation approach to embedding of virtual networks
(2015-07-21)
Article
Restricted access - publisher's policyAs the virtualization of networks continues to attract attention from both industry and academia, the virtual network embedding (VNE) problem remains a focus of researchers. This paper proposes a one-shot, unsplittable ... -
Autonomic resource management in virtual network
(2012)
Conference report
Restricted access - publisher's policyVirtualization enables the building of multiple virtual networks over a shared substrate. One of the challenges to virtualisation is efficient resource allocation. This problem has been found to be NP hard. Therefore, most ... -
Contributions to efficient resource management in virtual networks
(2014-06-30)
Article
Restricted access - publisher's policyNetwork virtualisation is a promising technique for a better future Internet by allowing for network resource sharing. However, resource sharing requires that virtual nodes and links be embedded onto substrate nodes and ... -
Design and evaluation of algorithms for mapping and scheduling of virtual network functions
(2015)
Conference report
Restricted access - publisher's policyNetwork 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, ... -
Design and evaluation of learning algorithms for dynamic resource management in virtual networks
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Conference lecture
Open AccessNetwork virtualisation is considerably gaining attention as a solution to ossification of the Internet. However, the success of network virtualisation will depend in part on how efficiently the virtual networks utilise ... -
Dynamic resource management in SDN-based virtualized networks
(2014)
Conference report
Restricted access - publisher's policyNetwork virtualization allows for an abstraction between user and physical resources by letting a given physical infrastructure to be shared by multiple service providers. However, network virtualization presents some ... -
Management and orchestration challenges in network functions virtualization
(2016-01)
Article
Open AccessNFV continues to draw immense attention from researchers in both industry and academia. By decoupling NFs from the physical equipment on which they run, NFV promises to reduce CAPEX and OPEX, make networks more scalable ... -

Network Function Virtualization: state-of-the-art and research challenges
(Institute of Electrical and Electronics Engineers (IEEE), 2015-09-04)
Article
Open AccessNetwork Function Virtualization (NFV) has drawn significant attention from both industry and academia as an important shift in telecommunication service provisioning. By decoupling Network Functions (NFs) from the physical ... -
Neural network-based autonomous allocation of resources in virtual networks
(2014)
Conference report
Restricted access - publisher's policyNetwork virtualisation has received attention as a way to allow for sharing of physical network resources. Sharing resources involves mapping of virtual nodes and links onto physical nodes and links respectively, and ... -
