In Sept, 2015，China Unicom released the white paper on new-
generation network architecture CUBE-Net 2.0, which set the
guideline for network transformation based on SDN/NFV and cloud
新网络 New Network —
SDN/NFV, UBB
新服务 New Services —
NaaS, NFaaS, Cloud ICT
新生态 New Ecosystem —
Open Source, Open Collaboration
High-level architecture of CUBE-Net

4. Network Requirement of enterprise customers
 Services flexibility: fast services providing, modifying,
and reconstructing for customers at any time, any places;
 Service control: based on Cloud+SDN+NFV technology,
pushing services fully from cloud side of telecom operators;
 Diverse service model: customers from end
site/office/home or from data center, supporting different
business type: B2B, B2C, C2C, etc.
 Ecological Environment construction : Competitive
(individual , internal);ecological (collective, external)

Integrated services including WAN connectivity and cloud
services for enterprises
 Access domain
• VPN access for enterprise tenants
 Backbone domain
• isolated virtualized networks for multi-tenant
 DC domain
• heterogeneous cloud platform access
• hybrid clouds networking (direct connect between
public cloud and private cloud )
 Management domain
• Open API
• enterprise to manage its VPN
 Service domain
• Network on demand
