A security policy is composed of entries defining the conditions to redirect a packet.

Ingress policy acts on traffic flow towards the network (or the OVS component).

The security policies are defined at the domain level.

The security policies deployed on the VSD are distributed ACLs implemented on the VRSs and NSGs.

It can be applied to the overlay.

It can be applied to the underlay.

VSD raises an alarm when the policing threshold is crossed.

The policer can be configured by enterprise admin.

CSP root group user

CSP CMS group user

Enterprise designer group user

Enterprise admin group user

They can track both TCP and UDP flows.

They can be created in either ingress or egress directions.

A packet in the direction of the stateful ACL rules will automatically create a “related” rule in the reverse direction.

The automatically created rules will not go away until the ACL is manually deactivated and reactivated.

An ‘overlay network’ is a virtual abstraction built on top of an existing physical network.

Both VXLAN and TRILL are host-centric overlay solutions.

Nuage Networks VNS uses a VXLAN-based overlay solution.

Overlay networks are totally transparent to their physical underlay network.
