In the long run, this will not only be important to strengthen the connectivity capacity throughout the EU, but also to balance out the prices of connectivity services, both for citizens and for network operators. The average budget for this between 2021-2023 is around of €130m. More specifically, this will be possible by funding key infrastructures such as submarine cables and, where necessary, improvements in connectivity with satellite ground stations. In particular, in the Outermost Regions, islands and Member States with coastlines, as well as the Overseas Countries and Territories where connectivity standards are often lower. The objective is to ensure high-quality connectivity in all parts of the Union. In the field of digital, she mentioned how important it is to make sure all parts of the Union can have equal access to open and secure internet.ĬEF Digital will contribute to this Global Gateway strategy by supporting the deployment of backbone connectivity and networks throughout the EU. In her 2021 State of the Union speech, Commission President Ursula von der Leyen highlighted the need to strengthen strategic connectivity within the European Union through Global Gateway partnerships. Backbone connectivity plays a fundamental role in ensuring that our internet traffic remains strong and consistent despite growing data flows. That traffic goes from a source computer to a Tier 3 ISP that routes it to a Tier 2 ISP that routes it to a Tier 1 backbone provider that routes it to the appropriate Tier 2 ISP that routes it to a Tier 3 access provider that delivers it to the destination computer.Did you know that most of the internet traffic today passes through submarine cables that are fundamental to connect Europe with its islands and Outermost Regions and the rest of the world? It is these same submarine cables that help provide backbone connectivity, transporting big volumes of information across extended geographical areas. This arrangment makes it possible for traffic from a computer on one side of the world to connect to one on the other side. Traditional backbone network construction and O&M pay more attention to meeting. In order to do that, Tier 2 ISPs contract with Tier 1 ISPs for access to the global backbone, and in that way make the entire internet accesssible to their customers. It is an important part of IT infrastructure for financial institutions. So often Tier 3 ISPs contract with Tier 2 (regional) ISPs that have their own networks that can deliver traffic to a limited geographic area but not to all internet-attached devices. These providers have no access of their own to the internet backbone, so on their own would not be able to connect their customers to all of the billions of internet-attached computers.īuying access to Tier 1 providers is expensive. What is the internet backbone Like any other network, the internet consists of access links that move traffic to high-bandwidth routers that move traffic from its source over the best available. Tier 3 providers provide businesses and consumers with access to the internet. How traffic gets on the backboneīelow the Tier 1 ISPs are smaller Tier 2 and Tier 3 ISPs. These routers are made by vendors including Cisco, Extreme, Huawei, Juniper, and Nokia, and use the border gateway protocol (BGP) to route traffic among themselves. The internet backbone is made up of the fastest routers, which can deliver 100Gbps trunk speeds. Such agreements eliminate potential financial disputes that might have the result of slowing down internet performance. Participating Tier 1 ISPs help fund the IXPs, but don’t charge each other for transporting traffic from the other Tier 1 ISPs in a relationship known as settlement-free peering. These are often owned by third parties, sometimes non-profits, that facilitate unifying the backbone. Internet exchange points (IXP) tie the backbone togetherīackbone ISPs connect their networks at peering points, neutrally owned locations with high-speed switches and routers that move traffic among the peers. They are actually two protocols, transport control protocol and internet protocol that set up connections between computers, insuring that the connections are reliable and formating messages into packets. In addition to being physically connected, these backbone providers are held together by a shared network protocol, TCP/IP. By joining these long-haul networks together, Tier 1 ISPs create a single worldwide network that gives all of them access to the entire internet routing table so they can efficiently deliver traffic to its destination through a hierarchy of progressively more local ISPs.
