WHAT IS...?

SD-WAN is a virtual connectivity platform that separates network control and management from the data plane, using a service agnostic underlay. As such, SD-WAN acts effectively as an overlay, on top of existing network infrastructure.

The public Internet is a complex mesh of almost one hundred thousand different, but ‘open’ network. At the core of the Internet is the Internet backbone provider. Here you can find out more about its fundamental principles.

IP Transit is a wholesale Internet access service which facilitates access for AS networks to the rest of the Internet via the border gateway protocol (BGP). This guide explains how it works.

DWDM has played an important role in optical networks, and increased the data capacity and utilization of the physical fiber dramatically. DWDM technology is based on the combination and transmission of multiple optical signals, with dedicated wavelengths simultaneously using the same fiber cable. Here’s how it works…

Border Gateway Protocol (BGP) is effectively the universal navigation system of the Internet, a digital postal service that provides the necessary routing information for public Internet networks, or autonomous systems (AS) to steer traffic to each other. Learn more about it here.

RPKI is a secure identification system for BGP updates between autonomous systems. It reduces the risk of accidental route leaks and hijacks – learn how it works here.
