Businesses and individuals may elect to migrate some or all of their applications and systems to the cloud for a number of reasons, among the most frequently quoted are: Competitive AdvantageBusinesses judge that moving to cloud-based services will provide them with a competitive advantage over other companies. There may be many ways in which an advantage may be quantified but they could include faster or more flexible responses to changing market conditions and the ability to roll new products and services out more quickly than would have been possible with a legacy IT architecture. The three following drivers can also...

Recorded: 23rd November 2021 Cloud computing has revolutionized the way IT Services are deployed and used, allowing major improvements in flexibility, availability, and simplification, whilst offering opportunities to speed up time to deploy new services and realise cost savings. The core technology behind Cloud based services is virtualization; could this be leveraged to provide the same benefits to the communications market? Many communications services are of course based on software applications, which do lend themselves to virtualization and thus cloud deployment. However, communications are also dependent on connectivity services – can virtualization of these services be modelled and managed in a...

5G, Network Virtualization -

The 5G core network architecture is designed to be cloud native making use of NFV (Network Function Virtualisation) and SDN (Software Defined Networking). NFV is used to decouple the logical function of a network element from its associated hardware and implement that function in software as a VNF (Virtualised Network Function). The VNF may be run on general purpose, off the shelf computing platforms. The VNF may be run on general purpose, off the shelf computing platforms. The main feature of SDN is a clear separation between control and user plane functions. SDN supports centralisation of control plane functionality while at the same time supporting...

Networks have passed the point where they need to evolve to meet the growing demands placed upon them, not only for the insatiable demand for modern services but for an ever-increasing number of connected devices requiring uninterrupted connectivity. Software Defined Networking (SDN) and Network Functions Virtualisation (NFV) have made inroads into the deployment and management of communication networks. They provide an agile and scalable solution to meet changing demands in minutes, which would previously have taken days or weeks to resolve. By taking hardware that can be virtualised and deployed on a common infrastructure with shared networking resources, efficiencies can...

SDN (Software Defined Networking) is an approach to data networking in which the control functions are decoupled from the physical infrastructure. This allows network administrators to support a dynamic, manageable and cost-effective network making it ideal for the high-bandwidth nature of today’s applications. SDN addresses the fact that the static architecture of conventional networks is not suited to the dynamic computing and storage needs of modern data centres, campuses, and network operator environments. A communications protocol known as OpenFlow is considered as an enabler of SDN. OpenFlow enables remote controllers to determine the path of packets through the network of...
