“As more and more IP and optical elements become virtualized and distributed, network operators need a more efficient and flexible way to manage and orchestrate a diverse ecosystem of service-dependent transport resources,” said Uwe Fischer, Executive Vice President, R&D and PLM, and Chief Technology Officer, Coriant. “Our new SDN Hierarchical Controller significantly enhances efficiencies in integrated IP-Optical networks with advanced automation and programmability. These field-proven capabilities represent key enablers of Coriant’s visionary Hyperscale Carrier Architecture, which provides operators a pragmatic means to transform multi-layer infrastructure for a new generation of end-user services, including 5G, IoT, and virtual reality.”
As a leading global provider of multi-layer transport solutions, Coriant continues to enhance its portfolio with advances in IP/MPLS and packet optical integration, and the Coriant Transcend™ SDN Hierarchical Controller is a central element of an integrated control structure. The SDN Hierarchical Controller gathers inputs from optical, packet optical, or IP/MPLS SDN domain controllers and builds a stateful topological view utilizing a multi-layer data model. A multi-layer control structure enables a broad range of network configuration, visualization, and reporting functions for advanced multi-layer and multi-domain networks. Since the solution supports open interfaces to domain controllers, both Coriant and third-party networks can be integrated into a single network control environment.
Key features and benefits of the Coriant Transcend™ SDN Hierarchical Controller include:
· Orchestration of multi-layer transport resources to bring SDN-enabled efficiencies, optimization, and control to Layer 0-3 access, aggregation, and core networks
· Open standard interfaces for flexible integration into diverse workflow orchestration and OSS environments, including multi-vendor integration through open southbound RESTful interfaces to third-party controllers
· Context Optimized Routing Engine (CORE) that provides path computation for multi-layer performance-aware services
· Shared Risk Link Group (SRLG) awareness of transport services that supports optimized resource assignment and multi-layer service status aware routing
