IP Networks

The evolution of networks towards IP, and their architectures, is a chapter in the history of Telefónica in each of the countries in which it operates, which has its origin in the late nineties, and continues to this day. IP (Internet Protocol) networks have become the platform for transporting traffic for all services in the last 25 years of Telefónica’s century.

In this history, the evolution of Telefónica’s IP networks in Spain plays a prominent role, due to its undisputed leadership in the creation and use of these, leveraged on the success of the Internet and fixed and mobile broadband.

At Telefónica, it was soon foreseen that IP technology was going to end up being used to implement all services: the new Internet access services and the new television over the copper loop, and also those of the company’s data networks and telephony itself, which had been the sustenance of the business in the first 75 years of the company’s life.

This notebook describes the history of Telefónica’s IP networks and demonstrates, once again, Telefónica’s technological leadership.
