SOFTWARE DEFINED NETWORKING FOR OPTICAL TRANSPORT NETWORKS WITH VIRTUORA®
CENGN, Fujitsu and TELUS have come together to demonstrate control of OTN services using the Virtuora® Network Controller (NC) and the FLASHWAVE® 9500 and FLASHWAVE CDS optical networking platforms. Integrating an open source SDN controller, the Fujitsu-TELUS proof-of-concept shows how a Path Computation Engine (PCE) feature is automated to build optimal routes for services, improving resiliency and speed of restoration if an interruption occurs to a network.

SDN PROJECT OVERVIEW
Scenario 1: Network and Topology Discovery
In this scenario, the Gateway Network Element (GNE) will be added as a policy component to an OTN network that is already provisioned. This will demonstrate how the topology discovery process works.
Scenario 2: Service Creation
Three types of services will be presented:
•Unprotected and protected services (1+1, SNC/N)
•Constrained routing (e.g least cost or least latency) at node and Shared Risk Link Grouping (SRLG) levels
•Service diversity
These three types of services will illustrate how creating and/or deleting services can be automated using the Virtuora product suite.
Scenario 3: Fault Aware Service Routing
This scenario will test how loss of signal is handled and implemented. This is measured through service-affecting alarm and fault identification.
Scenario 4: Dynamic Service Restoration
This scenario is designed to show how Virtuora performs Service Restoration and path computation.
EVOLUTION OF OTN SERVICES
Before SDN, in the early 2000s, the development of optical control plane standards defined discovery, routing, and signaling functions for networks. Ever since, Generalized Multi-Protocol Label Switching (GMPLS), Automatically Switched Optical Networks (ASON) and Overlay architectures have been used to support dynamic services like bandwidth-on-demand, customer-initiated service requests, scheduled or time-of-day based services, and dynamic service restoration. These earlier versions of optical transport planes were a precursor to SDN/NFV, which now includes free and open source applications and protocols that anyone can customize.
Figure 1: Virtuora NC framework for network control and management
The Virtuora product suite delivers end-to-end operational automation, service orchestration and network programmability. More specifically, Virtuora centralizes optical control plane and network infrastructure functions. Using the notion of functional disaggregation, i.e. undoing proprietary integration, the controller allows for the connection from one vendor’s transponder to another vendor’s reconfigurable optical add-drop multiplexer (ROADM). Fujitsu is a founding member of the Open ROADM initiative, which promotes open interfaces to connect ROADM elements. ROADM elements enable remote configurability without the need of human intervention.
The Fujitsu-TELUS proof-of-concept demonstrates how Virtuora can control the OTN shown in Figure 2. In order to improve functionality and efficiency, the Virtuora Product Suite architecture implements SDN/NFV network programmability and automation, including unified operations, resource orchestration and virtualization.
