Teleriga

Teleriga is a term used in some telecommunications literature to denote a ring-based telecommunication network architecture designed to provide redundancy and fault tolerance. The word combines tele- (distance) with a root meaning “ring” in certain languages, and its exact etymology varies by context. In a teleriga, network nodes are connected in a closed loop so data can travel in either direction around the ring. This allows automatic re-routing of traffic in the event of a link or node failure, reducing packet loss and downtime.

Implementation typically relies on established optical or packet technologies, such as fiber-optic links in a ring topology, protection switching mechanisms, and control protocols that monitor link health. Common variants include one-plus-one or one-to-one protection, where a spare path can carry traffic if the primary path fails. Teleriga architectures may incorporate multiplexing (like SDH/SONET, Ethernet over fiber) and can be deployed in metro, regional, or data-center backbones.

Historically, ring topologies have been used since the early days of fiber networks to provide resilience at reasonable cost. In modern practice, the concept persists in metro Ethernet rings and survivable IP/MPLS backbones, though the exact terminology may differ by vendor.

Because teleriga does not denote a single standardized specification, definitions and features can vary between organizations and regions. When encountered, it usually refers to the broader family of ring-based, fault-tolerant telecommunications fabrics rather than a specific protocol.
