SDN and NFV in network realisation
SDN (Software Defined Networks) and NFV (Network Function Virtualisation) are two developments in the networking field that are complementary. SDN is mainly mentioned as a function within computing centres, with the example of how Google has set up the networks within its computing centres.
In the first presentation by Prof Robert Meijer TNO was shown, that SDN has been implemented by PhD students from the UvA (University of Amsterdam) on a global scale in a virtual network with routers based on NFV over PaaS (Platform as a Service).
These routers are located in centres of Amazon around the world.
This was followed by a number of practical examples, where the implementation of SDN is already happening.
The entire network within a wafer stepper at ASML is based on this, but also in the network within modern commercial aircraft. In the future, we will also start to see clusters of small satellites that are part of a common SDN network for communication.
In the second lecture by Wim van der Bijl Cap Gemini covered NFV provision in depth, showing how NFV is related to SDN. The benefits of the new network setup were discussed in detail. Management and Orchestration features were also discussed.
Finally, Jurrien Veldhuizen spoke about the practical application of SDN and NFV. Unfortunately, these slides are Huawei-confidential.
With regard to NFV, it clearly emerged that there are still major problems with the implementation of management functions for NFV, which do not allow a practical application well.
The interfacing of network hardware with the Management and Orchestration function is still insufficient to undefined, preventing the use of equipment from different vendors.
It became an extremely interesting evening about innovations and limitations in modern networks.
Description
The Department of Telecommunications invites you to the lecture evening on the theme: SDN (Software-Defined Networking) and NFV (Network Function Virtualisation) in network realisation.
SDN and NFV are usually mentioned in the same breath, yet are different things that both have a big impact in building networks.
In SDN, the control software is taken out of the network devices and centralised, allowing the function of the network to be controlled by central software and greatly simplifying the management of a complex network. The application of SDN takes place mainly in computing centres.
With NFV, specific network functions such as those normally provided by a router or a modem are virtualised on a standard IT infrastructure, so that the specific network functions are provided software-based. NFV is currently of particular interest to telecom operators that provide network services to customers and would like to become more flexible and independent of hardware.
As an example, the home router/modem is built specifically for a provider by a hardware vendor. With NFV, a telecom operator could provide a standard server with router/modem software for the home and manage it remotely for the end user.
