A system assigns, to selected network devices in an intelligent transport network, a policy domain marker that identifies a particular network operation policy. The network devices that receive the policy domain marker delineate a region of enforcement for the particular policy. After an appropriate waiting period to permit the selected network devices to advertise their policy domain marker, the system distributes, to all network devices in the intelligent transport network that support control plane signaling or control plane routing, an enforcement signal to enforce the particular network operation policy for the delineated region.

Node marking for control plane operation

The present disclosure relates to systems and methods for providing bandwidth-on-demand telecommunications services over next-generation optical transport networks (NG-OTN). One embodiment of a system providing bandwidth-on-demand services includes a next-generation optical transport network (NG-OTN) having an intelligent control plane (ICP) and new-generation synchronous optical network (NG-SONET) capabilities. A next-generation operation support subsystem (NG-OSS) is communicatively coupled to the NG-OTN. The NG-OTN and the NG-OSS are configured to provide the bandwidth-on-demand services.

Bandwidth-on-demand systems and methods

A system includes one or more active/working circuit groups to transfer information through a protection domain, the protection domain defined by a plurality of network devices and a plurality of links connecting the network devices between a start point and an end point; and a protection circuit group through the protection domain, the protection circuit group being disjoint from the one or more active/working circuit groups to provide shared protection for the one or more active/working circuit groups, where the protection circuit group is comprised of an individual protection circuit and where a capacity of the protection circuit group is dynamically adjusted based on a capacity of the one or more active/working circuit groups.

Flexible shared mesh protection services for intelligent TDM-based optical transport networks

Systems and methods are provided to implement a full-time protection mechanism and a new class of service offerings based on mechanisms to achieve an 'always protected' type of transport service for a networking environment where there may be multiple failures or synchronized attacks. This suite of services may utilize intelligent control plane technology in the optical transport network to support an 'always on' protection capability.

System and method to support full-time protection services in a network

A device receives a traffic fencing (TF) function for a network, and provides a TF attribute, based on the received TF function, over a link of the network to enable activation of a TF rule of a link state routing (LSR) algorithm used by the network to implement the TF function for the network.
