More About Arelion

Arelion operates as an international telecommunications provider that delivers IP-based network services and connectivity to carriers, content and application providers, and large enterprises. It stems from Telia Company’s global carrier business, which built and operated a worldwide Internet backbone and wholesale connectivity portfolio. Arelion focuses on network infrastructure and services that enable IP transit, transport, and interconnection across regions and between major digital hubs.

The company’s offerings are typically used in enterprise and institutional environments where predictable performance and reach are required for distributed applications, content delivery, and multi-site connectivity. Organizations such as cloud providers, content platforms, communication service providers, and large corporate networks use Arelion’s services to connect data centers, cloud regions, and end-user networks. These services can function as the underlay for Software-Defined Wide Area Network (SD-WAN), Virtual Private Network (VPN), and other overlay architectures that enterprises deploy on top of IP and optical transport.

Arelion’s portfolio centers on IP transit and related Internet backbone services (network connectivity), where the company provides access to global routing capabilities using standard Internet protocols such as Border Gateway Protocol (BGP) (Border Gateway Protocol) over high-capacity backbone links. In optical transport (network transport), the company offers Ethernet and wavelength services over DWDM-based fiber infrastructure, supporting point-to-point and metro/long-haul connections between data centers and core sites. These services typically integrate with enterprise routers, switches, and optical platforms using standard Ethernet and optical interfaces.

Cloud and data center connectivity (cloud networking) forms another focus area, where Arelion connects enterprise locations, carrier networks, and data centers to cloud platforms and interconnection points. Customers can use these services to build multi-cloud or hybrid cloud architectures by linking private infrastructure with cloud regions through dedicated network paths, instead of routing traffic solely over the public Internet. This positioning places Arelion in the same general marketplace category as other global backbone and wholesale connectivity providers, while remaining tied to Telia Company’s heritage in international carrier services.

In wholesale voice and interconnect services (voice and interconnect), Arelion enables operators and service providers to exchange international voice traffic and related communication services. This part of the portfolio uses established signaling and routing standards and integrates with carriers’ existing voice and IP infrastructure. Across these domains, Arelion’s directory positioning aligns with global Internet backbone services, IP transit, optical transport, cloud and data center connectivity, and wholesale voice and interconnect offerings aimed at carriers, digital service providers, and large enterprises that require cross-border, multi-region connectivity.
