In 5G proposals, functionality of the BBU is disaggregated into a DU and a CU that handle BBU functionality according to different functional splits. A significant amount of cloud infrastructure is envisioned to be needed to implement several of the designated splits. An integrated device (e.g., white box) can integrate the functionality of multiple RRU (or NR in 5G) and the functionality of multiple BBU (or DU/CU splits in 5G). By performing a lightweight routing determination at the integrated device, requisite cloud infrastructure can be significantly reduced.
