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.

DDoS attack stands for "Distributed Denial-of-Service (DDoS) attack" and refers to a bombardment of an Internet entity with a huge amount of data traffic in order to destabilize the system and disturb regular data flow.

The benefits offered by cloud technology explain its widespread adoption in today's globally interconnected network landscape. Simply defined, the term 'on-ramp' is 'a short road that provides access to a highway or other main road'. Learn more here.

Network security is the protection of network infrastructure from unauthorized access, misuse, or theft. Learn more here.

Dark fiber services are for those that need a lot of traffic between two endpoints and at the same time want to have full control of the network at the highest security level. Learn more here. 

Dedicated Internet Access or DIA is a direct, private-line connection, ensuring fully dedicated IP connectivity with a high level of security. DIA is the critical point where your own network meets the Internet. Learn more here. 

Network latency can be defined as the time delay incurred when transmitting data between a source and its destination. It is a critical consideration in the telecommunications industry, especially as the demand for real-time applications and services continues to grow. Learn more here. 

Network redundancy exists where technologies and strategies are implemented within a network to preserve network stability by reducing or eliminating disturbances and downtime. Learn more here. 

A flash call is an authentication method for verifying identity without requiring any specific action from the end-user. It is a relatively new technique for implementing two-factor authentication (2FA). Learn more here.

VPN (Ethernet Virtual Private Network) is a WAN technology used to extend Layer 2 and Layer 3 connectivity between different network sites and segments. It is commonly used for interconnecting Layer 2 networks within and between large data centers. Learn more here. 

An E-LAN connection is an any-to-any or multipoint-to-multipoint Layer 2 Virtual LAN service that connects two or more user points or sites, offering a full mesh connectivity. Learn more here.

Internet rankings serve as a valuable tool for diverse stakeholders and decision-makers, including users, businesses, policymakers and researchers, offering important insights into Internet performance, market dynamics, security threats, and policy implications.

A network map is a visual representation of the various links and elements in a network. It illustrates physical and even logical relationships within a certain geographical area, making it easier to manage and monitor the network - and plan for future growth.

A managed network is a service where providers assist in building and maintaining a core network – ensuring it grows efficiently, quickly, and is sufficiently scalable for evolving business needs.

Toll-free numbers (starting with 8xx) allow callers to make free calls, with costs covered by the recipient. They are billed for incoming calls.

Virtual phone numbers, or VoIP numbers, are not tied to a specific device or location, offering flexibility and allowing users to be reached anywhere.

In today's digital age, enterprise cybersecurity is essential for protecting organizations from evolving cyber threats. It involves a comprehensive set of processes, rules, and measures designed to prevent and mitigate network attacks.

In a complex networking world, the difference between underlay and overlay network technologies and functionality is useful to understand.
