There are many forms of disaggregation, but true network disaggregation means that each network function is run on a standard server with open-stack software. Network function virtualization (NFV), which is one aspect of network disaggregation, makes the network scalable and flexible, without becoming locked-in to a given vendor.
It is easy to see the benefits of NFV for 5G, as a virtualized network is more agile and costs less up-front. However, NFV comes with some challenges as well. For one thing, the transition from a rigid network structure is not trivial, which is why very few operators are fully committing to NFV at this point. Furthermore, NFV can add latency, which is a complete no-go for 5G.
