Sample architectures

Now, let’s look at some sample architectures where the previously described components, technologies, and principles come together. The major components are the network hardware, the virtualization layer, the applications, and the enterprise cloud. Figure 4.9 is not meant to muddy the waters more but to provide yet another perspective on the various edge realms:

Note that an access point (AP) is a term used to describe a network device that allows wireless devices to connect to wired networks. Transport is defined as the network infrastructure providing connectivity to various customer services. It typically connects the RAN and the core network. In the case of 5G, it provides the network slicing function.

Note

In 5G RAN architecture, it is possible to split the two functional units: the distributed unit (DU), responsible for real-time functions, and the centralized unit (CU), responsible...
