Coriant is expanding its Transcend SDN Solutions portfolio with the introduction of a packet controller optimized for mobile backhaul and carrier aggregation networks. Combining the Coriant Transcend SDN Transport Controller and Coriant Transcend SDN Packet Controller enables full, end-to-end network control – from optical transport to IP/MPLS access and aggregation networks.
Coriant said its new Transcend SDN Packet Controller supports a broad range of packet-based access and aggregation transport network use cases, including:
- Automated provisioning via customer portals
- Dynamic load distribution based on network congestion
- Alarm-based service re-route to reduce network instability
- Automated assignment of SRLG LSPs over diverse optical paths
- Low latency services
- WAN integration with virtualized and cloud-based services
Key features of the Coriant Transcend SDN Packet Controller include:
- Programming interfaces built upon standards-based interfaces (RESTCONF/YANG) for seamless interoperability with third-party OSS, orchestrators, and applications. The open API framework simplifies end-to-end service provisioning and enables automated synchronization between IP/MPLS and optical layers for enhanced multi-layer traffic engineering and optimization.
- A centralized Path Computation Element (PCE) that defines traffic flows based on real-time performance criteria in addition to traditional routing algorithms for context-optimized path computation and routing (e.g., routing based on network congestion or underlying optical transport paths). These capabilities have been shown to enable network operators to increase network utilization, improve network reliability, simplify operations, and deliver performance-aware services, while enabling efficiency improvements that can generate CapEx savings of up to 35%.
- Support for new and currently deployed network elements, as well as interoperability with existing NMS deployments, including the Coriant® 8000 Intelligent Network Manager (INM), to enable seamless migration and a non-disruptive roll out of network-wide SDN programmability.
“The introduction of the Coriant Transcend SDN Packet Controller follows upon successful completion of Tier 1 customer and multi-vendor interoperability trials,” said Paul Smelters, Executive Vice President, Product Management and Marketing, Coriant. “This solution significantly strengthens the Coriant Transcend™ SDN Solutions portfolio by advancing SDN-enabled IP/Optical interworking at a time when network operators are looking to simplify multi-layer architectures without sacrificing scalability, flexibility, or resiliency.”

Blueprint: The Age of Swiss Army Knife Transponder
by Dr. Danish Rafique and Dr. Maxim Kuschnerov, Coriant What does the term flexibility signify for the optical transport business? In today’s market space, this is a challenging question, as the degrees of freedom are practically limitless. Over the last decades, the industry has exclusively focused primarily on increasing transport bandwidth or overall capacity per fiber. However, simple bit loading beyond 100G interfaces has resulted in significantly…
Coriant Adds to its Transcend SDN Platform
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…
