The public Internet is a complex mesh of almost one hundred thousand different, but ‘open’ networks - linked together with an almost limitless inventory of network hardware and millions of kilometers of fiber-optic cable. In technical terms, these are known as Autonomous Systems (AS). An AS is essentially a unique collection of IP addresses/address blocks and network hardware within a common administrative domain. Autonomous Systems communicate route information and steer traffic to each other using a protocol known as the Border Gateway Protocol, or BGP.
The Internet backbone can be simply defined as the core of the Internet. Here, the largest and fastest networks are linked together with fiber-optic connections and high-performance routers. Internet networks are primarily owned and operated by commercial, educational, government or military entities. Collectively, they facilitate a stable foundation for the Internet Service Providers (ISPs), content and cloud providers who provide Internet access or online content, applications and services to end-users and businesses.
The largest providers are known as Tier 1 networks. Positioned at the top of the Internet ecosystem, these networks are sufficiently comprehensive that they don’t purchase IP Transit from anyone else. Tier 1 networks exchange Internet backbone traffic on the basis of privately negotiated interconnection agreements, usually on the principle of settlement-free IP peering. In general, networks lower down in the hierarchy pay for upstream IP Transit and networks of similar size and merit peer with each other. Arelion (AS1299) is one of the largest and best connected global Tier 1 providers today. As a Tier 1 network owner we can reach every other network on the Internet solely via settlement-free interconnection. Our AS1299 is currently ranked #1 and our IP customers account for nearly 65% of all Internet routes. Whether you're a startup or Fortune 500, our network is the backbone of your business - connecting you directly to everything and everyone that matters.
The Internet is massive and immense, so who is its owner? The answer is no one, i.e., there is no organization, no company nor person that owns the complete Internet. Even control of the Internet is not regulated on a common level, though some governments have been trying to introduce a more controlled Internet for their specific location, but on the global level there is no organized control.
Internet infrastructure is on the other hand owned by some large communication companies.
Whilst Internet connectivity is often viewed as a commodity, performance can vary significantly between suppliers. When selecting an Internet backbone, there are a number of important things to consider:
Reach - a larger footprint generally means a service provider has greater control of network resources, and ultimately, quality.
Scalability - is a backbone built on leased capacity or own infrastructure? This will dictate the ability of a supplier to scale-up capacity, quickly and efficiently.
Proximity - How well connected is a backbone with the rest of the Internet and in what tier do they reside?
Connectivity – Does a backbone connect via third party transit networks and public exchanges or through a well-managed ecosystem of private peering connections with critical networks?
We use our own optical fiber backbone that spans thousands of kilometers across the world. We control, operate, and monitor all our routes to ensure cable stretches and exact fiber routings are thoroughly checked, documented, and maintained. We apply a rigorous process to all fiber routes, including fast, in-field action for fiber repairs to maintain high fiber availability.
Internet backbone maps depict the connections between different points of presence (PoP), making it easier for customer to see and define the shortest way to connect keeping the best possible quality and cost.
See Arelion’s Network maps as a good example.
Serving customers in 125 countries, our 70,000 km fiber backbone spans North America, Europe and Asia. Our PoPs give you a direct route to the world’s best content and billions of end-users. Fiber-up control of our network with cutting-edge optical and IP technology deliver the scalability you need, whenever you need it.
