60 Software Networks
virtualized in datacenters present at the central or regional level, but
can also be found in the femto-datacenters situated on the periphery.
Indeed, the Wi-Fi access points (Nodes-B or e-Nodes-B) require
hardware, and must be close to the user. These boxes also facilitate the
easier introduction of 5G, which we shall look at in more detail in
Chapter 6. Indeed, the Internet of Things requires new interfaces that
are well suited to the “things” in question. These interfaces can be
handled by specially-designed virtual machines.

3.4. Automation of the implementation of software
networks
An important point in the advent of the new generation of software
networks, whether in terms of the core network or the LAN, relates to
automation for the establishment, management and control of
personalized networks designed in the context of software networks,
which may be SDNs or use legacy architectures, or indeed a mix of
the two, given that each software network is entirely independent of
the others. With this in mind, as indicated by Figure 3.9, we need to
add an auto-piloting system to the general architecture. The basic
domains to be piloted are the servers, storage facilities and networks,
but we also need to add security and management elements, which
have become absolutely indispensable for the proper operation of a
complete system.
