The evolution of ultra-broadband services has brought about the need to innovate telecommunications networks, in terms of functions, performance, management and monitoring systems, offer to the end user.

Nowadays, copper networks represent one of the bottlenecks to access network capacity, especially with regard to over-the-top (OTT) services (cloud computing, social networks, video streaming, etc) that are creating an enormous rise in the bandwidth demand.

The shift to Next Generation Network Access (NGAN) can benefit from a widespread use of fibre optics to reach final users. There are various options: Fibre to the Home (FTTH); Fibre to the Building (FTTB); Fibre to the Curb (FTTC) and copper wires to the end user (for example, through the use of VDSL2 Vectoring technology). In addition, fibre optics can be used with point-to-point or point-to-multipoint connections based on a Gigabit Passive Optical Network (GPON) technique.

Fibre optics will improve the mobile network (3G and 4G) performance, allowing the connection of all base stations with extremely high bit rates.

The migration towards packet technologies will have to meet the needs of many services that require specific features in terms of quality and reliability.  This in turn willtrigger the need to identify new techniques and routing protocols (from the Multi-Protocol Label Switching to the Carrier Ethernet and Generalized Multi-Protocol Label Switching, to the Optical Burst Switching and the Optical Packet Switching).
