More flexible

?

Networks are deployed using command lines. Small service changes will lead to heavy network modification by administrators. Network faults are more likely to occur on a large scale. Network deployment and maintenance are inflexible.

Open

The network policy model changes dynamically on demand. The redundancy capability of high elastic clusters and standard southbound and northbound interfaces enable high network deployment capability.

Open platform for northbound applicationsSupports the standard OpenStack Neutron model and Apps to allow third parties to schedule network services through northbound interfaces, providing differential services.

Drag-and-drop experience, WYSIWYGProvides GUI-based service dragging and orchestration capabilities to meet separate or collaborative computing and network provisioning.

Application-oriented network orchestrationImplements policy control and Service Function Chain based on terminal groups. Network policies automatically migrate with terminal groups, without manual intervention.
