Sekundaarvõrk

Sekundaarvõrk, often translated as secondary network, refers to a network that complements or supports a primary network infrastructure. In telecommunications, it might represent an alternative or backup route for data transmission, ensuring service continuity in case of primary network failure. This can involve physical redundancy, such as duplicate fiber optic cables, or logical redundancy, employing different transmission protocols or routing paths.

In the context of electrical power systems, a secondary network is a low-voltage distribution network that serves a concentrated area, typically a dense urban environment. It provides a more resilient power supply by interconnecting multiple primary feeders. If one feeder fails, the load can be automatically or manually rerouted through the secondary network, minimizing disruptions to consumers. This design enhances reliability, particularly for critical services like hospitals or data centers.

The concept of a secondary network also extends to IT and computer systems. Here, it might refer to a backup or disaster recovery network that mirrors the primary operational network. This allows for a swift transition to the secondary system if the primary network experiences an outage, corruption, or security breach, thereby maintaining business operations. The implementation and complexity of a secondary network depend heavily on the specific application and the required level of resilience.
