Intro
Operators' Intention on Open Network
Moving towards an End-to-end Open Network To build an end-to-end open network will be a long process. It is rational to focus on some easier parts and localized scenarios at first
Open Radio Access Network China Unicom is active in TIP and O-RAN Alliance to promote an Open RAN, which is essential for building a more flexible and scalable end to end network
Open 5GC N4 Interface and White-box UPF UPF is an important anchor for local traffic steering and providing vertical services. N is the key
Open Edge Computing China Unicom is promoting unified cloud-native Paus architecture in standard and open source alliances, maximizing the value of edge computing and building ecosystem with partners.
Open Optical Network Open Optical Network is based on standard Sel and NBL China Unicom has developed unified management controller and orchestrator which support multi-vender equipment Interoperation
White-box Switches Develop customized white-box switches and system based on open source software according to China
Further Consideration on Open Network Open network is always a comples, controversial, but inevitable topic. To enhance internal ability and expand ecological cooperation, meanwhile change business modes are essential
