Guide to SDN, SD-WAN, NFV & VNF

A deluge of buzzwords in the field of the networking industry often creates confusion for the ordinary reader. So many acronyms, similar to one another, and even the core technologies behind each one of these acronyms builds into another, with overlapping themes, which adds further confusion into the picture. It becomes difficult to understand their working and functionalities in a clear and distinct way.
Cisco vs VMware SD-WAN

No matter which market share report is considered, either Cisco or VMware holds the top SD–WAN vendor ranking. Both these giants have been battling for supremacy in the SD–WAN market ever since they began to spend millions of dollars in this field. Cisco paid 600 million dollars to buy Viptela in 2017, and VMware paid 450 million dollars to buy leading SD–WAN startup VeloCloud in the same year.
How To Deploy A DIY SD-WAN?

We have seen a rapid increase in the deployment of SD-WAN by organisations of all scales. It is essential to understand the various methods of SD-WAN deployment. Generally, there are two approaches to deploying software-defined networking: managed SD-WAN providers and do-it-yourself (DIY) methods. In the latter approach, any external service provider is not hired for the deployment of SD-WAN. Instead, it is managed and set up by the company’s own IT teams.
SD-WAN Helping Work From Home

COVID-19 dominates working life today. Office staff throughout the world have settled into their work-from-home set-ups. Nevertheless, a significant portion of the global population do not have access to broadband internet at home; even more have weak internet connections. Working from home rarely offers the high-quality connections employees enjoy at the office. Freelancers also suffer a similar problem. Individuals and organisations are therefore looking for technologies that will enable productivity as working from home continues.
Digital Transformation with SD-WAN

SD-WAN (Software-Defined Wide Area Network) is a virtual wide area network that has revolutionised how users connect to their applications, no matter where the application resides. Previously, 80% of applications were located in branch offices or core datacenters, and communication was through a leased line, usually MPLS. This has changed today. With the emergence of the public cloud and the adoption of the public cloud by enterprises, applications can be literally anywhere.
VeloCloud vs Fortinet SD-WAN

We live in an ever-changing era of information technology, where emerging technologies are increasingly dictating the way we do business and run operations. Technologies come and go, but SD-WAN, a comparatively new entrant in the network infrastructure, has shown surprising traction.
Is a Telco needed for SD-WAN?

A Software-Defined Wide Area Network (SD-WAN) is a network that abstracts the hardware layer of equipment, making a virtual network overlay. With this technology, users can communicate across branch offices over large distances and at lower costs.
