Cisco Crosswork Optimization Engine 1.2 with NSO 5.2 v1

July 2020

The Segment Routing PCE is a feature of IOS-XR. The Crosswork Optimization Engine is an application that provides a user interface for the Segment Routing PCE. The Crosswork Optimization Engine displays the real-time network state including topology and traffic information as well as information on Segment Routing policies and the path the SR Policies traverse through the topology. In addition, the Crosswork Optimization Engine can be used to create new PCE initiated policies that have a defined path or dynamic path optimized for IGP metric, TE metric, or delay. The Crosswork Optimization Engine is an application that leverages the Cisco Crosswork infrastructure and micro-service architecture.
