NFV PHD THESIS

In he was awarded the Nokia Achievement Award for his work on cooperative networks. We will end the session with how leveraging applications to the edge helps meet the stringent requirement for 5G. As a concrete solution, the thesis presents Glasgow Network Functions GNF , a container-based NFV framework that allocates and dynamically orchestrates lightweight virtual network functions vNFs at the edge of the network, providing low-latency network services e. By simulation, the positive effects of the proposed routing and aggregation strategy and the usefulness of the algorithm. At the same time, future networks are aiming to push services to the edge of the network, to close physical proximity from the users, which has the potential to reduce end-to-end latency, while increasing the flexibility and agility of allocating resources. Cziva, Richard Towards lightweight, low-latency network function virtualisation at the network edge.

This allows implementation of a centralised control that takes the state of the entire network into account and configures nodes dynamically to avoid congestion. The optimisation being studied both with respect to total end-to-end delay and maximum end-to-end delay. PhD thesis, University of Glasgow. To cope with these challenges, service providers are exploiting softwarised, cost-effective, and flexible service provisioning, known as Network Function Virtualisation NFV. Communication networks are witnessing a dramatic growth in the number of connected mobile devices, sensors and the Internet of Everything IoE equipment, which have been estimated to exceed 50 billion by , generating zettabytes of traffic each year. At the same time, future networks are aiming to push services to the edge of the network, to close physical proximity from the users, which has the potential to reduce end-to-end latency, while increasing the flexibility and agility of allocating resources. Owing to its complexity, we propose a tabu search heuristic and numerically show that it is faster than the mathematical formulation by many orders of magnitude.

  GOLDER COLLEGE PREP SUMMER HOMEWORK

To be able to study the impact of control functions, some parts of the environment is fixed, such as the topology and the node capacities, and statistically average the traffic distribution in the network by randomly generated traffic matrices.

Due to state dependencies in space and time, the network dynamics are very complex, and resort to a simulation approach. In he was awarded the Nokia Achievement Award for his work on cooperative networks. To cope with these challenges, service providers are exploiting softwarised, cost-effective, and flexible service provisioning, known as Network Function Virtualisation NFV.

Towards lightweight, low-latency network function virtualisation at the network edge

Contact us The University of Glasgow is a registered Scottish charity: However, the heavy footprint of today’s NFV platforms and their lack of dynamic, latency-optimal orchestration prevents them from being used at the edge of the network. It eliminates the dependency between the network function software and hardware enabling pure-software based network function that runs on commodity hardware, called Virtualized Network Function VNF.

Communication networks are witnessing a dramatic growth in the number of connected mobile devices, sensors and the Internet of Everything IoE equipment, which have been estimated to exceed 50 billion bygenerating zettabytes of traffic each year. In particular, we tackle the online placement of VNFM to enable network operators to adjust the number and location of VNFMs in thewis to variation in workload.

NFV, along with other emerging technologies such as Software-Defined Networking SDNenables network operators to create dynamic and programmable network services, wherein VNFs are deployed on-demand, dynamically chained and optimized over time to cope with emerging business needs.

He co-founded several start-up companies starting with nnfv GmbH in Berlin in On the algorithmic side, a key challenge is to identify the number and location of the NFVO rhesis VNFM functional blocks since they have a significant impact on the overall system cost and performance, among others.
