What is Redundant Communication?
Redundant communication means that a system or network has multiple independent communication pathways, reducing the risk of total failure. The purpose is to ensure that critical communication can be maintained even during outages or attacks.
How does Redundant Communication work?
- Multiple network paths: If one channel is disrupted—for example, during a power outage or cyberattack—traffic can automatically be rerouted through an alternative path.
- Technological diversification: Redundancy can be achieved by combining different technologies, such as fiber, mobile networks, satellite communication, and radio.
- Automatic fault handling: Systems can detect failures and switch to a working connection without manual intervention.
Why is Redundant Communication relevant?
- Enables the continued operation of vital societal functions during network disruptions.
- Reduces the risk of data loss during attacks, technical errors, or physical damage to infrastructure.
- Strengthens crisis preparedness by providing multiple communication channels for emergency services, authorities, and municipalities.
Redundant communication is a way of embedding resilience into infrastructure and can be critical to keeping society functioning when something goes wrong.
