Open Network and China Unicom's Practice
summary
China Unicom says it is moving piecewise from proprietary stacks to production open network elements: a cloud-native 5G base station one-box that merges baseband control, L3 compute and edge apps; a defined white box UPF with M4 interface and a lightweight UPF for private 5G verticals; an open metro DWDM with unified controller and REST northbound for data center interconnect; and a network OS (extended from SONiC) called CENO running on customized whitebox switches, with ongoing performance and integration work.
