Posts about SDN

In recent years, SDN and NFV have matured from technologies with potential into mandatory requirements for agile, fast and cost-efficient production of communication services. We’re now seeing widespread deployment with communication service providers (CSPs) implementing ambitious digitization projects. Many CSPs are combining this with a transition towards full automation and even autonomous operations, while also minimizing the amount of proprietary hardware. Standard hardware components in combination with network operating systems and software appliances will form the networks of the future ...

Amid all of the technological and architectural changes taking place in data infrastructure heading into 2019, the elephant in the room is the internet of things. Even without the prospect of millions – no, billions – of connected devices feeding data back to processing centers, and vice versa, the world was on a trajectory of exponentially larger volumes every year. Now, that process has been kicked into even higher gear, and networks are on the front lines in the effort to keep it all on track ...

Did you visit any of this year’s major communication conferences? If so, I’m sure you noted service providers and vendors talking a lot about the increasing relevance of the network edge. There’s a common understanding that powerful edge servers will soon be hosting virtual network functions and control processes in proximity to the customer or an enterprise appliance. But what might look like a logical complement to central clouds needs to be seen as a disruptive change to long-standing network design best practices, with complexity being centralized to create economies of scale and operational savings. So what created this shift in network architectural preferences and how will this unfold next year?

Communication service providers are adopting a range of approaches to 5G. Some are focusing on fixed wireless access as a substitute to copper or fiber transport. Others see huge opportunities in accessing sensors with new narrowband radio access technologies such as NB-IoT and LTE-M. There is also great value in end-to-end virtualization, aka slicing, for offering customized private mobile networks to enterprises and governments ...

Inflexible and monolithic transport network solutions are little use when it comes to meeting the agile connectivity requirements of the cloud, 5G and IoT. Networks must be able to respond immediately to changing bandwidth needs. Complex network planning and time-consuming, failure-prone manual provisioning processes are no longer an option. Networks need to support and eventually replace slow processes with automation and intelligent control ...
