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. To cope with these challenges, service providers are exploiting softwarised, cost-effective, and flexible service provisioning, known as Network Function Virtualisation NFV. Contact us The University of Glasgow is a registered Scottish charity: In this thesis, the opportunities of bringing NFV to the network edge are identified. Having worked as everything from unix sysadmin to Chief Technical Officer with a number of leadership roles in between, Van has contributed to technologies from mobile, enterprise data centre, multi-national networks and beyond.
This role has her speaking at conferences around the world, and spreading the word about the strength of the NFV Ecosystem. He has been involved in several international, EU, national and industrial research projects: Most hands-on sessions will be performed by using virtual machines. This thesis will try to accommodate as much traffic as possible, and study the effect of routing and aggregation on a rather general mix of traffic types. Tuesday, November 27, —
This thesis will try to accommodate as much traffic as possible, and study the effect of routing and aggregation on a rather general mix of traffic types.
NFV Management and Orchestration in Large-Scale Distributed Systems
He has been involved in several international, EU, national and industrial research projects: The load in the network depends on many factors, such as thesos characteristics and the traffic matrix, topology and node capacities.
We will end the session with how leveraging applications tjesis the edge helps meet the stringent requirement for 5G. In particular, we tackle the online placement of VNFM to enable network operators to adjust the number and location of VNFMs in response to variation in workload.

Tutorials – IEEE Conference on Network Function Virtualization and Software Defined Networks
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. PhD thesis, University of Glasgow. Full text available as: We will talk about how 5G applications can meet these requirements and thesie the Network Transformation technologies that help meet these goals.
The optimisation being studied both with respect to total end-to-end delay and maximum end-to-end delay.
Assumes that node controls can pdh expressed in commands supported by OpenFlow v1. This allows implementation of a centralised control that takes the state of the entire network into account and configures nodes dynamically to avoid congestion.
Since traffic is stochastic in nature, high demand may arise anywhere in a network and possibly causing congestion.
The tutorial is split into two sections: This thesis elaborates and addresses key architectural and algorithmic research challenges related to the NFV management and orchestration in distributed and large-scale systems. Congestion results when demand temporarily exceeds capacity and leads to severe degradation of Quality of Service QoS and possibly loss of traffic.
At the same time, future networks are aiming to push services to the edge of the network, to close physical proximity from the users, ohd has the potential to reduce end-to-end latency, while increasing the flexibility and agility of allocating resources.
In he was awarded the Nokia Achievement Award rhesis his work on cooperative networks. The results also show that GNF can carefully manage the placement of vNFs to provide low-latency guarantees, while minimising the number of vNF migrations required by the operators to keep the placement latency-optimal. Van spent much of her career as a contractor, working for every telco as well as major retailers in Canada over the years.
He is author or co-author of more than papers published in international journals, books, and conferences in networking, with particular reference to performance modeling, cross-layering, wireless networks, cognitive radios and networks, green networking and smart grid communications.

The results also show that GNF can carefully manage the placement of vNFs to provide low-latency guarantees, while minimising the number of vNF migrations required by the operators to keep the thdsis latency-optimal. We also propose an architecture of Virtual Network Platform-as-a-Service VNPaaS that utilizes the hierarchical orchestration to offer next-generation mobile networks as-a-service. Today, the network is used for content delivery, e.
In this thesis, the opportunities of bringing NFV to nfb network theesis are identified. 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.
We will also touch upon how the audience in the room can leverage these technologies and help move these forward.
Towards lightweight, low-latency network function virtualisation at the network edge
There are different ways to mitigate the effects of congestion, by rerouting, by aggregation to take advantage of statistical multiplexing, and by discarding too demanding traffic, which is known as admission control. Towards lightweight, low-latency network function virtualisation at the network edge.
The first wave of NFV was about taking a network function and running it as-is in a virtual environment. 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.
