Open Networking Summit Europe 2019

5G is coming to scale deployment with its appealing killer application on-demand slice automation, which has been the most highlighted use-case of ONAP community lately. 3GPP SA5 defines the 5G slice management reference architecture. TMF discusses the linkage with BSS and 3GPP slicing system. There are multiple implementations of 5G slicing based on ONAP. This presentation summarizes the different ways in which the three ONAPs support slice orchestration and management implementation. It discusses the possible deployment methods of different operators using ONAP to support slicing in different scenarios, and how to further improve the various projects of ONAP to support the next step of improvement of these deployment methods, including collaboration proposals with the relevant standards organizations.
