This WWT-guided lab demonstrates several aspects of Cisco's Crossword Network Controller (CNC) in conjunction with Cisco NSO, including path control with Cisco SR-PCE (Path Computational Engine). CNC is a Segment Routing SDN Controller for transport networks. CNC allows an operator to create and manage VPN and Transport services with diverse SLAs, such as disjointness, bandwidth awareness, or low latency. It provides for creating engineered transport paths using SR-TE parameters and provisioning and linking VPN services to these paths. CNC performs real-time network optimization based on current network conditions utilizing the Crosswork Optimization Engine in conjunction with Cisco's IOS-XR-based Segment Routing Path Computation Element or SR-PCE. Cisco NSO is also included and tightly coupled to CNC as the Provisioning engine.
