Network control is fully integrated into the forwarding plane.

SDN supports cloud computing by automating virtual machine instantiation.

The API interface provides a way to program the SDN switch directly.

The SDN controller provides global provisioning of network devices.

A host vPort is provisioned on VRS-G, while a bridge vPort is provisioned on VSG.

A host vPort is provisioned for VLAN traffic, while a bridge vPort is for VxLAN traffic.

A host vPort only supports one VLAN, while a bridge vPort can be configured with multiple VLANs.

A host vPort requires static MAC address configuration, while a bridge vPort learns MAC addresses dynamically.

A managed L2 domain has one or more zones and each zone can have multiple subnets, each with its own IP address pool, while an unmanaged L2 domain does not have zones or subnets.

Managed L2 domains can have overlapping IP address pools, while unmanaged L2 domains are not allowed to have overlapping IP address pools.

In a managed L2 domain, Nuage Networks VCS manages security policies, while in an unmanaged domain, Nuage Networks VCS cannot manage the security policies.

In a managed L2 domain, Nuage Networks VCS performs DHCP and ARP proxy functions, while in an unmanaged domain VCS has no visibility of IP addresses.
