A network device implements resource admission policy management related to controlling the denial or grant of a delivery of a network service to a customer device. The network device receives a notification related to a change in network topology or network capacity of a network that delivers the network service. The network device identifies changes in the network topology or the network capacity based on the notification, and applies resource admission control to deny or grant the customer device access, to resources of the network to receive delivery of the network service, based on the identified changes in the network topology and/or the network capacity.
