Coriant unveils Transcend Hierarchical Controller for SDN topologies

Coriant has added the Transcend Hierarchical Controller to the Coriant Transcend Software Suite. The controller offers enhanced orchestration of multi-layer, multi-domain, and multi-vendor transport networks by leveraging software-defined networking (SDN) automation and programmability to accelerate service activation, optimize Layer 0-3 resource allocation and resiliency, and improve multi-vendor interoperability and end-to-end control, the company says.

The SDN hierarchical controller assembles input from optical, packet optical, and/or IP/MPLS SDN domain controllers and uses it to build a stateful topological view of the network using a multi-layer data model. The Transcend Hierarchical Controller's principal features and benefits, according to Coriant, include:

  • Orchestration of multi-layer transport resources to bring the benefits of SDN to Layer 0-3 access, aggregation, and core networks
  • Open standard interfaces, including open southbound RESTful interfaces to third-party controllers
  • The Context Optimized Routing Engine (CORE), which provides path computation for multi-layer performance-aware services
  • Shared Risk Link Group (SRLG) awareness of transport services, which supports optimized resource assignment and multi-layer service status aware routing.

Coriant will show off its Transcend Software Suite as well as elements of its optical transport systems line at the Next Generation Optical Networking (NGON) conference June 20-22 in Nice, France.
