Service providers need to scale and improve the cost efficiency of multi-layer networks, including both the IP layer and the transport layer. The first step starts with the strong foundation of an Infinera Intelligent Transport Network. Extending SDN to transport requires a hardware and software architecture that supports an ability to abstract optical wavelengths into pools of optical capacity and to be able to map any service from 1 GbE up to 100 GbE and beyond into those pools. Infinera's Intelligent Transport Network and DTN-X platform with PIC-based super-channels creates large, efficient pools of DWDM bandwidth that are combined with 5 Tb/s of OTN switching and an intelligent GMPLS control plane to support Bandwidth Virtualization. This abstraction enables a simplified, programmable bandwidth services model, in contrast with other solutions that propose direct control of the analog transmission layer via heavy NMS systems which may hit scale and transaction rate challenges. Infinera’s approach includes the full software abstraction of the transport layer through Open Transport Switch, a lightweight virtual transport switch that, when combined with an SDN control layer, can deliver programmable, open, and automated control of the transport layer.

With that foundation in place it is possible to control and monitor both the transport layer and the IP layer via the OpenFlow protocol and other complementary web 2.0 protocols to speed multi-layer provisioning and optimization. We believe this Transport SDN solution delivers key benefits to network operators:

  • Scale networks quickly by facilitating programmable deployment of optical bandwidth and IP resources to quickly to support application-driven bandwidth demands
  • Efficient resource utilization by optimizing the path taken through the multi-layer network and minimizing transit traffic through the router layer, thereby reducing the total amount of overprovisioning. Based on application requirements, efficient and cost-effective mesh protection within the intelligent transport network can also help reduce overprovisioning in the IP layer
  • Lower opex by automating operations across the network layers, eliminating device-by-device configuration at the router layer, and coordinating resource provisioning functions along with the intelligent transport layer
  • Speed to revenue by enabling a single screen or API for provisioning, monitoring and optimization of multi-layer services
