Coriant is rolling out a set of new capabilities for its Transcend SDN Transport Controller including enhanced multi-layer optimization and standards-based service interworking. The company’s approach is to combine SDN with its packet optical transport and smart router products to enable dynamic, end-to-end network control in an open network environment. The platform is currently in customer trials.
“The lack of efficient interworking in multi-vendor transport networks makes it challenging for network operators to meet dynamic, high-capacity service demands in a fast, cost-effective, and profitable way,” said Uwe Fischer, Chief Technology Officer, Coriant. “We’ve taken a highly focused approach to our SDN developments to give our customers the tools to easily apply SDN-enabled automation, programmability, and control to practical applications like rapid service creation in multi-layer IP Optical networks.”
Newly released features for the Coriant Transcend SDN Transport Controller include:
- Efficient service interworking – enabled by support for the industry-standard IETF RESTCONF interface and YANG data modeling language. These enhancements provide an open API framework for efficient utilization of an abstracted and virtualized photonic layer. This enables automated synchronization between IP and optical layer SDN controllers for enhanced multi-layer traffic engineering, including optimal path computation and dynamic control based on real-time configuration data such as link status, route diversity by Shared Risk Link Groups (SRLGs), and latency.
- Simplified service provisioning – enabled by enhancements to the platform’s SLA-based service provisioning engine. With the addition of new automated and programmable service provisioning and management capabilities, including advanced SLA monitoring and user-defined SLA parameters, network operators can enhance service differentiation and translate real-time performance data into actionable end-user reports.
- Enhanced resource utilization – enabled by optical impairment-aware multi-layer Path Computation Element (PCE). This feature enhancement enables optimal allocation of network resources according to service requests and SLA parameters, assuring the best path in the network for service traffic based on optical impairments, path restrictions, equipment and fiber status, and specific service-defined constraints such as latency.
- Flexible network partitioning – enabled by network virtualization and varying levels of network abstraction. Enhanced network slicing features provide network operators the tools to virtually apportion segments of the network across multiple products and layers to satisfy the specific requirements of a particular end-user. For example, network slicing can be used to partition services for a retail carrier in a wholesale environment, a large enterprise, or an internal service provider client (e.g., IP Services business unit).
Coriant Intros Transcend SDN Orchestrator based on OpenDaylight
Coriant launched its Transcend SDN software suite, providing an advanced programming environment and open interfaces that empower on-demand, application-centric service agility and monetization of network assets. The solution combines many of Coriant’s SDN and NSV solutions: Coriant Transcend Orchestrator based on the OpenDaylight Project, the Coriant Transcend Transport Controller, the Coriant Transcend Application Suite, and integration of Open…
