HP DCN Overview
HP DCN is a Software-Defined Networking (SDN) solution that enhances data center (DC)
network virtualization by automatically establishing connectivity between compute resources
upon their creation. Leveraging programmable business logic and a powerful policy engine,
HP DCN provides an open and highly responsive solution that scales to meet the stringent
needs of massive multi-tenant DCs. HP DCN is a software solution that can be deployed over
an existing DC IP network fabric. Figure 1 illustrates the logical architecture of the HP DCN
solution.
