The document discusses the importance of the underwater communication cable network in South America for digital communications and evaluates its infrastructure regarding national and economic security. It highlights the connectivity status of nodes, noting that San Juan, Puerto Rico is the most connected while San Andres, Colombia is the least connected, with limited direct connectivity to Asia and Africa. The analysis also includes network centrality and community detection but concludes that only two of the top ten connected hubs are located in South America.

3. Why the underwater communication
cable network is important ?
● Internet
● All forms of digital
communications
from video streaming
to a simple telephone
call

4. Goal: Evaluation of the Infrastructure
Sovereignty
● National Security
● Economic Security
● Optimization

5. Network Analysis “Data Collection”
● Cable information →
different companies→
nodes in South
America.
● Big network that
connects all the cables
with their capacity.

6. Network Analysis: Node Connectivity
● The most connected is San
Juan, Puerto Rico (USA).
● The least connected is San
Andres, Colombia.

7. Network Analysis: Network Centrality

8. Network Analysis: Closeness Centrality

9. Network Analysis: Community Detection
“Community Map”

10. Network Analysis: Community Detection
“Community A”

11. Network Analysis: Community Detection

16. Conclusion
● Only 2 of the top 10 most
connected hubs are located in
South America.
● Zero direct connectivity with
Asia.
● Limited connectivity with
Africa and Europe and only
from Atlantic Coast.
