The Resource Control software suite provides IP path control, visualization, and optimization functions, as well as multi-layer IP/optical discovery, visualization, and coordination.

The Resource Control feature packages are:

• Control and Visualization Starter

• Path Control and Optimization

• Simulation

• Enhanced Optimization

• Multi-layer Discovery and Visualization

• Multi-layer Control and Coordination

Note: High availability is provided for the NSP functions by default with feature packages from the resource control suite.

The Control and Visualization Starter feature package provides visual representations of the IGP and MPLS topologies, and enables traditional MPLS, control-plane, and brownfield LSP configuration.

For this function, the Virtual Service Router - Network Resources Controller (VSR-NRC) acts in a Virtual Network Function (VNF) capacity to perform topology discovery. The VSR-NRC implements the southbound Path Computation Element (PCE) function using the PCEP, BGP-LS and IGP protocols.

The Path Control and Optimization feature package enables a stateful or stateless PCE to provide paths to requesting LSPs via PCEP/BGP based on a path profile. The feature package also provides the ability to invoke maintenance practices either manually or automatically based on event notifications.

Note: To deploy Path Control and Optimization, you must also deploy the Control and Visualization Starter feature package.

The Simulation feature package is a traffic-engineering tool for network engineers. The tool enables the design of highly optimized traffic flows, and enables the offline simulation of operational assurance changes to assist in capacity planning.

Note: To deploy Simulation, you must also deploy the following feature packages:

• Control and Visualization Starter

• Path Control and Optimization

The Enhanced Optimization feature package offers automated closed-loop optimization for live network deployments using telemetry and data analytics to trigger automated actions.

The functions provided by the feature package use the MDM and OAM frameworks to accomplish the required tasks.

Note: To deploy Enhanced Optimization, you must also deploy the following feature packages:

• Control and Visualization Starter

• Path Control and Optimization

Note: If your network includes 7250 IXR gen 1 devices, Enhanced Optimization requires the flowCollection installation option in the Platform feature package..

The Multi-layer Discovery and Visualization feature package provides IP/optical topology discovery, path diversity verification, and bottom-up and top-down navigation. The MDM framework is used to establish T-API based interfaces towards an Optical domain controller. This then enables the IP/optical coordination capabilities.

Note: Although the feature package requires no other dependencies to view the transport topology, including the LAGs, the Control and Visualization Starter feature package is also required to view the IP/MPLS (LSP) topology; contact Nokia Professional Services for guidance.

The Multi-layer Control and Coordination feature package supports single-step LLI establishment, maintenance coordination, cross-domain connection management, and floating port restoration. The multi-layer control and coordination service is deployed on the NSP cluster.

Note: To deploy Multi-layer Control and Coordination, you must also deploy the Multi-layer Discovery and Visualization feature package.

Note: For multi-layer optimization use cases, you also require the following feature packages:

• Control & Visualization Starter + Path Control and Optimization (for multi-layer optimization only), or

• Control & Visualization Starter + Path Control and Optimization + Enhanced Optimization (for the extra precision/options of telemetry-based optimization and/or traffic-engineered ECMP)
