Combinatorial Auction-Based Resource Allocation in the Fog

Network service composition is becoming increasingly flexible, thanks in part to advances in virtualisation and cloud technologies. As these penetrate further into networks, providers are often looking to leverage this infrastructure to improve their service delivery. This desire poses a number of obstacles, including a diversity in device capabilities and the need for a value exchange mechanism. In this demonstration, we present a platform that seeks to address a selection of these challenges

Siren:a platform for deployment of VNFs in distributed infrastructures

Fog computing is conceiving an Internet where general purpose compute is ubiquitous, in turn this is providing new infrastructures for Network Functions Virtualisation (NFV). However, current NFV designs focus on the Cloud, resulting in broken and suboptimal deployments when deploying to the Fog. Through a case study with preliminary results, this paper presents the e ectiveness of Siren: a new prototype platform designed as a tool to deploy and manage Virtual Network Functions in Fog environments

Siren:A platform for deploying virtual network services in the cloud to Fog continuum

The burden put on network infrastructures is changing. The increasing number of connected devices, along with growing demand, are creating an unsustainable future for the Internet. The recently introduced concept of Fog computing predicts a future Internet where general compute power is ubiquitous, extending the Cloud right the way to the network edge. In turn, this acts as a catalyst for Network Functions Virtualisation (NFV), increasing the potential infrastructure locations for deploying new services, specifically ones that can cater to the demands of the changing Internet. However, current realisations of NFV typically host network functions in homogeneous, centralised servers in Cloud infrastructures. This is in contrast to the Fog where environments are both distributed and heterogeneous, thus current management and orchestration platforms suffer from suboptimal service deployment. With the use of a multiple use cases, and a novel auctioning orchestration method, this paper presents Siren, which is an orchestrator for network functions in the Cloud to Fog continuum

Scalable and responsive SDN monitoring and remediation for the Cloud-to-Fog continuum

Since the inception of the digital era the sharing of information has been revolutionary to the way we live, inspiring the continuous evolution of computer networks. Year by year, humankind becomes increasingly dependent on the use of connected services as new technologies evolve and become more widely accessible. As the widespread deployment of the Internet of Things, 5G, and connected cars rapidly approaches, with tens of billions of new devices connect- ing to the Internet, there will be a plethora of new faults and attacks that will require the need to be tracked and managed. This enormous increase on Internet reliance which is stretching the limits of current solutions to network monitoring introduces security concerns, as well as challenges of scale in operation and management. Todays conventional network monitoring and management lacks the flexibility, visibility, and intelligence required to effectively operate the next generation of the Internet. The advent of network softwarisation provides new methods for network management and operation, opening new solutions to net- work monitoring and remediation. In parallel, the increase in maturity of Edge computing lends itself to new solutions for scaling network softwarisation, by deploying services throughout the network. In this thesis, two proof-of-concept systems are presented which together harness the use of Software Defined Networking, Network Functions Virtualisation, and Cloud-to-Fog computing to address challenges of scale and network security: Siren is an open platform which manages the resources within the Internet, bridging network and infrastructure management and orchestration. Tennison is a network monitoring and remediation framework which tackles monitoring scalability through adapting to network context and providing a suitable architecture to the network topology, including the use of centralised, distributed, and hierarchical deployments
