RETn

RETN is an acronym used in the telecommunications industry that can refer to two related subjects: a regional Ethernet transport concept and a specific multinational operator, RETN Global Communications.

Regional Ethernet Transport Network refers to a class of transport infrastructure that uses Ethernet technology to interconnect data centers, metro networks, and service provider POPs across multiple sites. RETN architectures are designed to carry large-scale IP traffic with scalable bandwidth, low latency, and predictable performance. They enable a range of services, including IP transit, private line, virtual private networks, and cloud connectivity, typically leveraging multi-site Ethernet backbones, diverse routing paths, and robust redundancy.

RETN Global Communications is a multinational telecommunications operator that markets international IP transit, Ethernet transport, and related managed services. The company operates a backbone network that links multiple regions and serves carriers, enterprises, and content providers. Core offerings commonly include IP transit with BGP-based routing, dedicated Ethernet or private line services, VPNs, cloud connect, and colocation, often accompanied by service-level agreements and network monitoring. The provider emphasizes low-latency, high-capacity connectivity and flexible support models to accommodate diverse customer requirements.

History and market role: RETN Global Communications emerged from regional carrier roots and expanded to deliver international connectivity, focusing on adaptable deployment options and customer-centric service. The RETN transport concept remains relevant for carriers and enterprises seeking scalable, Ethernet-based transport solutions, and it has influenced the design of regional and global networks used to interconnect data centers and cloud services.
