Clarification • Schools can use the same boxes and wires that are also used to deliver the PSN • Schools connections are not bound by PSN compliance requirements • 2-2-4 network assurance is a requirement for PSN compliance. It is this that assures the separation of logical networks • Appropriately configured MPLS is one way of achieving separation. It is not the only way • You can also create corporate VPNs for sites that do not need PSN
