IP networks


The explosion of IP-based traffic – mostly driven by the fruition of HD-video content -, the widespread proliferation of mobile applications and devices, used anywhere and at any time for work and leisure, access to Cloud services, or the first Internet of Things (IoT) implementations are among the main signs of a major shift under way. Service Providers, Large Companies and Public Administrations are developing their networks toward “all IP” infrastructures in order to bring innovation and efficiency to their business.

A process of network simplification has therefore begun, which calls for the gradual disposal of obsolete infrastructures (PSTN, ATM, SDH, etc…), the reduction of protocol layers, and the abandon of specialized hardware platforms in favor of Network Function Virtualization (NFV) technology. Consequently, IP routing elements are gradually integrating with optical transport layer elements and the management of the services’ lifecycle is becoming increasingly agile and flexible, thanks to the proliferation of new Software Defined Networking (SDN) technology.

Optical fiber will be the most common carrier for the implementation of Ultra Broadband networks, whether for fixed access or for the supply of macro, micro 4G and, within a few years, 5G cells

As far as local networks are concerned, during the process of digital transformation companies will rely more and more on Wi-Fi networks, while the Internet, thanks to its growing reliability, will be increasingly used for the interconnection of the company offices.


Service Providers have been caught between declining margins, due to the competition of Over-The-Top (OTT) players, and the need to improve their networks in order to meet the growing demands for bandwidth and speed when delivering services stemming from the market.

Simplifying the network in an “all IP” logic causes a significant reduction in the management costs of the network itself, thus allowing to implement new business models and reduce the costs of services to business and residential customers.

To meet the new needs of the market, Service and Cloud providers must increase their company-oriented offer. The proliferation of new Network Programmability and Data Center logics ensures flexibility and simplicity in the integration of new services.

From the Enterprise point of view, quickly adopting new applications improves productivity, allowing companies to increase their agility and therefore take advantage of market opportunities faster than their competitors. The mobility offered by the pervasiveness of wireless networks (Wi-Fi/LTE) and the accessibility brought by the use of different kinds of devices (both business- and employee-owned) provide productivity gains, streamline business processes and optimize infrastructure costs.

Finally, it is important to emphasize that the enhanced efficiency of networks and services provided by Service Providers and Public Administrations leads to a general improvement of the services delivered to citizens.
