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)
