Transport architecture: Service level

“

(gentle music) - [Instructor] Now 5G is designed to support a wide range of services. So according to International Telecommunication Union, ITU, the 5G ecosystem is built around three key service types. One is enhanced mobile broadband. Second is ultra reliable low latency services, and third is massive machine type communication. So each of these services imposes unique demands on the transport network, particularly in terms of latency, throughput, and placement of network functions. So in 4G, we typically had a centralized code network with most network functions and compute storage hosted in a distant central data center. There was no concept of edge or regional cloud in that case. But with 5G, the architecture become highly distributed. There is a separation between the RU and DU at the cell site. The centralized unit split from distributed unit and placed at edge or regional data centers. The user plane function can now be deployed at either the core cloud or the regional cloud,…
