[Abstract] In this paper, CUBE-Net 2.0, the cloud-oriented dual-center decoupling and intensive network architecture for China Unicom is proposed. Optimizing the cost of overall construction and operation, CUBE-Net 2.0 states the layout of the network to be user and data center. Considering the specific requirements of the CUBE-Net 2.0 and the enterprise cloud services, the development overview and the main application scenarios of the E-CUBE network, as well as the key technologies of network cross-layer and cross-domain collaborations through E-CUBE are introduced. Combined with E-CUBE network evolution and development orientation, it is necessary for telecom operators to build a new operational ecology to adapt to the network changes.
