Accelerating Optical Wave Order-to-Provisioning Time by 90% using SDN Multi-Domain-Orchestrator

Optical wave provisioning for enterprise customers has been highly challenging and time consuming for CSPs as it requires different levels of inter-carrier agreements, complex integration and configuration of various network nodes across access, aggregation and core in a multi-domain/ vendor architecture. Such diverse traditional architecture lacks unified view of resource availability (e.g. network node, port availability in a particular router etc.) The long time taken for these activities delays the service provisioning by several days (even up to 45 days).

Implementing SDN Multi-Domain Service Orchestration (MDSO) is the solution to achieve touch-free provisioning.

By implementing SDN MDSO, CSPs can onboard multi-vendor domains and devices, achieve a unified view and control all domains from a single point. This helps in achieving touch-free dynamic provisioning of optical wave services.

Some of the benefits of implementing SDN-MDSO are:

• MDSO removes silos and enables better visibility of network and sub-network
• Reduced processing time in inter-domain service chaining
• Federation makes visualization and allocation of resources easier
• Increased utilization of network resources and decreased costs

This article further discusses on some of the key considerations for successful SDN- MDSO implementation for optical wave service. These recommendations can bring down your optical wave provisioning time from weeks to minutes.
