The benefits of IP-optical coordination

Build a nimbler network

Break down the operational and technological barriers that impede routing and transport convergence.


Ensure high network availability for a flawless user experience

  • Automatically discover accurate topology at all layers and cross domain interconnect information to allow effective engineering planning.
  • Ensure that true path diversity is present via deep insights into the optical network  architecture.
  • Coordinate control of activities such as restoration and network maintenance to prevent unwarranted impacts to end user traffic.

Improve your operational efficiency and service delivery velocity

  • Leverage insightful tools to allow bottom-up and top-down navigation and visualization across domains and layers.
  • Efficiently identify root causes of service affecting issues without complex inter-team dynamics.
  • Automate dynamic comprehensive service delivery across domain boundaries with open and programmable network interfaces.
Cost savings

Optimize your usage of routing and transport assets

  • Forward and protect traffic at the most economical network layer.
  • Run a hotter network without compromising reliability with cross-domain coordinated floating backup ports.
  • Deploy pluggable coherent router optics to deliver, assure and maintain high speed services rapidly and cost effectively in the 400G era and beyond.

IP-optical coordination use cases

400GE pluggable coherent optics automation

Efficiently deploy high speed connectivity

The introduction of powerful new 400GE coherent router optics  technology requires new capabilities for orchestrating and  automating IP-optical networks. NSP supports a  set of 400GE IP-optical reference use cases that constitute   solution blueprints for real-world deployments.

Topology discovery

Automated detection of the multi-layer topology

NSP can automatically and accurately detect topologies at all layers and gather cross-layer connect information to verify the network architecture is correct. Compared with error-prone manual techniques this can reduce the probability of service outages and enable simpler troubleshooting.

Diversity analysis

Assess true comprehensive path diversity

While path diversity is needed for IP links or for IP services, paths may not be fully diverse in the optical domain. A failure could  impact both primary & backup paths. NSP performs real time diversity analysis and can establish diverse paths as necessary. This can help reduce the probability of service outages.

Coordinated assurance

Rapidly troubleshoot network and service issues

NSP delivers the  ability to rapidly identify root causes of alarm conditions and coordinate resolution activities across teams. Operators have the ability to navigate bottom-up and top-down  in holistically  supervising network operation.  This brings efficiencies to multi-layer network operations.

Coordinated operations control

Minimize the effects of optical topology changes on IP traffic

Planned changes in optical topology, such as those that occur during network maintenance and hitless optical reversion can be coordinated with IP traffic routing to minimize impacts on end user services bringing improved customer satisfaction.

Cost-effective multi-layer protection

Cross-domain coordination to save on network equipment

The NSP enables cross-domain coordinated protection, intelligently and efficiently applied at the appropriate layer. Using a ‘floating’ backup port can bring considerable savings in the number of interfaces (router ports and transponders) required.

Cross-domain connection management

Interworking with 3rd-party domain controllers

The NSP supports automated connection management based on standard protocols and interworking with 3rd party domain controllers. This reduces the need for complex and expensive OSS systems with long integration intervals and manual, error-prone processes. This can allow faster service delivery and operational cost savings.
