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.

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.

Arelion Ethernet solutions offer secure, high-capacity networks with scalable bandwidth up to 40Gbps on 100GE interfaces and flexibility of EVPL and ELAN topologies. 

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…

Application-to-Person (A2P) messaging is one-direction messaging from an application to a person where no reply is expected. The utilization of A2P covers a broad spectrum, including notifications, PIN codes, 2FA (2-Factor Authentication) reminders and critical alerts to name a few. 

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.

Remotely Triggered Black Hole (RTBH) is best explained as “blocking undesirable data traffic at the edge of a network (based on either source or destination IP addresses) before it reaches the network”. Learn how it works here.
