Optical transport equipment supplier Coriant has released a new version of its Coriant Transcend SDN Transport Controller focused on addressing multi-vendor, multi-layer networking environments.

“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.”

The upgrades include:

  1. Efficient service interworking via support for the IETF RESTCONF interface and YANG data modeling language.
  2. Simplified service provisioning through changes to the platform’s service-level agreement (SLA) based service provisioning engine.
  3. Enhanced resource utilization via an optical impairment-aware multi-layer Path Computation Element (PCE). One can utilize network resources according to service requests and SLA parameters.
  4. Flexible network partitioning thanks to network virtualization and network abstraction.
