Resilience of telecommunications networks: A strategic key and competitive differentiator

In a world where constant connectivity is crucial, the resilience of telecommunications networks emerges as a strategic imperative. These networks, the cornerstone of our digital society, face multiple challenges, from cable damage and power outages to natural disasters and geopolitical tensions. Ensuring the robustness and stability of these networks is, therefore, an essential competitive differentiator for telecommunications operators.

Defining Resilience

The International Telecommunication Union (ITU) describes resilience as the ability of the network infrastructure to maintain continuous telecommunications services in the face of damage and various incidents. Essentially, it is the ability of operators to maintain acceptable service levels during and after disturbances or failures.

Strategies for Building Resilience

Telecommunications operators can strengthen the resilience of their networks through:

Redundancy: Alternative systems or routes in the network that are activated if primary ones fail.

Diversity: Multiple methods for performing functions, ensuring that if one method fails, another can continue operations. This also includes diversifying network routes.

Modularity: Network design that prevents a failure in one section from affecting the entire system.

Differences in Network Resilience

Resilience regulations vary by country, and operators have different approaches to what they consider sufficient resilience in their networks. Recent research indicates that less than half of operators conduct risk analysis or failure simulations, and only a small percentage carry out simulated attacks or disaster recovery analysis.

Applying Resilience by Design

Resilience for telecommunications operators should be an intrinsic feature in network architecture. Strategies such as power redundancy and capacity planning to prevent network overload are essential.

Robust Backup Routes

Redundancy is key in terrestrial and submarine networks. Additionally, establishing agreements with external providers for additional backup routes ensures the continuity of connectivity in the event of failures.

Deployment Strategy Anticipating Risks

With the increasing natural disasters and geopolitical uncertainty, it is vital to incorporate preventive resilience in the transmission network. This is achieved through route diversification and consideration of geopolitical risk zones in the deployment of submarine cables.

Investment in Hardware, Software, and Training

Regular network hardware and software upgrades are crucial, as is training operational staff in the latest network technologies and features.

Innovative Network Transformation

Operators are innovating to expand the capacity and footprint of their networks, for example, combining different networks to align them with the most demanding performance and quality of service requirements. Functionalities such as segmented routing allow for customized routes for different services, maximizing resilience for all services.

Continued Focus on Resilience

The resilience of the network is a continuous commitment for telecommunications operators, who invest in advanced technologies to ensure the robustness of their networks and maintain world-class service.

With a strategic focus on resilience, telecommunications operators not only fulfill an essential responsibility but also position themselves as trusted leaders in a highly competitive market, ensuring the reliability and continuity of service in all circumstances.
