Next Generation Converged Digital Infrastructure. 07/10/2020
Professor Nicholas Race.
Network Systems, University of Lancaster. Principal Investigator for NG-CDI.
The UK’s Digital Infrastructure is critical to the commercial and social activities and success of the country. It is essential that this infrastructure continues to be world leading. To keep ahead we need an infrastructure which responds quickly to changing needs, and at minimum cost. The creativity of the whole ecosystem will give rise to opportunities that we cannot predict. This means that services need to be configured in software rather than hardware to reduce the barriers to experimentation and scaling. Distributed autonomic technologies offer the opportunity to manage the expanding scale and complexity, and support faster ways to assess opportunities and risks, make decisions, and simplify service delivery. The operation of such an infrastructure will require new skills, cultures and practices. Nick introduces the research underway to deliver these aims & describes the approaches being taken and how the different aspect of the architecture fit together.
Intent Based Networking. 03/11/2020
Professor Ning Wang, Networks, University of Surrey.
Dr Harris Rotsos, Computer Networks, University of Lancaster.
Increasing the rate of delivery and value of new services will depend on smarter ways to capture customer needs and translate these into service definition and delivery. The research is investigating the capture of customer intents in machine-readable ways. The research covers not only service creation and DevOps, but also methods to maintain or re-negotiate service levels in real-time in the face of changing network dynamics, using autonomous distributed agent architectures.

Towards a µvnf monitoring architecture.
Will Fantom, Lancaster University. 22/10/2020
µVNFs are the next step towards network softwarization. Taking the form of containers and unikernels, they offer to networking many parallels with microservice architectures. This presentation introduces UniMon, a monitoring approach that integrates monitoring directly into unikernel VNF pipelines. UniMon can provide detailed, contextual, timely data, yet remain in keeping with the minimal nature of the unikernel. Also introduced is UniProbe, a unikernel based monitoring architecture that inserts unikernel µVNFs into heterogenous network infrastructures to perform in-network monitoring, enabling decentralized monitoring and policy enforcement. Collecting application specific metrics, the UniProbe architecture can also couple with modern DevOps workflows, supporting greater network automation.
Will Fantom is a PhD student at Lancaster University, investigating the roles that unikernels will play in next generation network infrastructure.
David Lake, University of Surrey. 22/10/2020
The talk will consider the development of P4 and P4 Runtime explaining how the notion of programmable networks has moved from the early days of OpenFlow. P4 as a programmable data-plane will be discussed as will P4Runtime as the network programming language associated with “Next-Generation SDN.” The Trellis architecture based around P4, P4Runtime and Stratum running on both hardware and software switches will be explained. Detail of current work to create a high-performance UPF based on P4 and P4Runtime using the open-source Free5GC components will explain how a mixture of hardware and software can provide the benefits of softwarization without compromising throughput in a 40Gbit/s UPF.
David Lake is a part-time PhD student at the University of Surrey and a member of the technical staff in the Office of the CTO at DELL.
IBN Demo presentation.
Mehdi Bezahaf, University of Lancaster. 24/09/2020
Recently, intent and Intent-Based networking (IBN) concepts have created enormous interest in academia and industry. The idea behind these concepts is to allow the user and the operator to express their intentions (i.e., a desire state or behavior) without the need to specify every technical detail of the process and operations to achieve it. In this talk, we introduce our technical demo on IBN from an Internet Service Provider (ISP) point of view. We present our intent implementation and demonstrate its utility in action in three use-cases (traffic engineering, predictive maintenance, and service protection period). It is still a work in progress and we keep updating our implementation with new use-cases.
Mehdi Bezahaf is a Senior Research Associate at Lancaster University, investigating future network architecture and network automation."
EPSRC Prosperity Partnerships
EPSRC has a strong track record of working closely with universities and business to develop high-quality funding programmes which deliver world-leading academic research whilst also delivering impact to business and the wider economy, through a variety of different routes.
Next Generation Converged Digital Infrastructure.
University of Bristol, University of Cambridge, Lancaster University, University of Surrey, BT. 01/11/2017
This EPSRC (Engineering and Physical Sciences Research Council) programme brings together a team of internationally renowned scientists and engineers working across top universities and BT. Together they will deliver the next generation converged digital infrastructure for the UK. This will create an agile, resilient network capable of meeting the future needs of our rapidly changing society and ensure that the UK’s digital infrastructure continues to be world leading. The partnership builds on long-term research collaborations between BT and each of the consortium’s members. This unique, multidisciplinary partnership with BT pioneers the way in which data science is harnessed with the latest research in networking.
Prosperity Partnerships: the first year.
New ideas and innovations are built on strong foundations of excellent research and fundamental science. That’s why, a year ago, EPSRC announced a really substantial investment to strengthen the links between the UK’s research base and business partners, driving innovation, growth and productivity. Here’s a quick update on some of the partnerships a year on.
