Introduction

Service Provider Networks are complex and multi-layer in nature. Without converged packet optical SDN capability, provisioning and adding bandwidth requires order of days, if not months. Since packet and optical networks are managed independently, each one of them has to be over provisioned to deal with traffic anomalies and failures. This leads to lack of service agility and is a significant source of CAPEX and OPEX overhead for the network operator.

This Tutorial demonstrates how ONOS can help address the challenges of managing multilayer service provider networks, by providing a sample demo on how converged packet-optical networks can be controlled by ONOS. We will introduce an emulated environment for converged control of packet and optical networks for wide area network, and show how it will truly enable service providers to use much more efficient traffic management practices.

Additionally, we will show ONOS’s capabilities as an enabler for cross-layer optimization, and applications on the northbound to control the forwarding planes at both the packet and optical layers. This environment can be used by the architects and developers to demonstrate feasibility of applications such as a multilayer PCE (MLPCE).  Through applications such as MLPCE  a much more optimized network solutions can be achieved in near real time. 

With Converged Control Plane, we hope to reduce cycle time to add capacity perhaps in minutes instead of days to a month. ONOS has the ability to add capacity based on traffic demand in real- or near real-time. In addition, when failure happens, instead of using the packet layer resources for recovery, ONOS can reconfigure the optical transport layer for best alternative re-route. With this approach, we are reducing the over-provisioning of resources, since transport layer is cheapest infrastructure to move bits. Finally, with enhanced converged control plane, we could potentially enable new services. Examples include network graph observability and real-time injection of network policies.
