Direction of Nontraditional SDN

When you design an enterprise or data center network environment using SDN principles, you should consider the following design directions:

Reuse existing infrastructure (investment protection).

Reuse existing technologies (mature) instead of increasing risks using OpenFlow.

Use overlay networking to enable application-driven end-to-end connectivity (for example, VLANs, VXLAN, Cisco Intelligent WAN [IWAN]).

Use an orchestrator to enable open programmability (for example, representational state transfer [REST]) and provide abstraction of network devices and topologies (simplification of service provisioning by using open APIs).

Choose the suitable Cisco products and software-defined networking (SDN) controller to optimize the management of the targeted environment:

Cisco Application Policy Infrastructure Controller (Cisco APIC) for the Data Center

Cisco Application Policy Infrastructure Controller Enterprise Module (Cisco APIC-EM) for WAN and Access
