Overview of Cisco Crosswork Optimization Engine
Cisco Crosswork Optimization Engine is part of the Cisco Crosswork Network Automation suite of products. Cisco Crosswork Optimization Engine provides real-time network optimization allowing operators to effectively maximize network utilization as well as increase service velocity.
Crosswork Optimization Engine provides the following:
-
A topology map that gives valuable real-time visualization of devices, links, link utilization, and TE tunnels (Segment Routing policies and RSVP-TE tunnels) in the network.
Note
Throughout this document TE tunnels refer to both SR policies and RSVP-TE tunnels.
-
A UI that allows for easy manageability of TE tunnels. Crosswork Optimization Engine enables the network operator to perform the following tasks:
-
Provision TE tunnels and modify or remove them using an intuitive workflow
-
Continuously track TE tunnel dynamic path computations to maintain SLA objectives
-
Preview TE tunnels before deploying it to the network
-
-
Crosswork Optimization Engine function packs (with correct licensing) that provide closed-loop optimization to define the optimization intent, implement the intent, and continuously monitor, track, and react to maintain the original intent. For more information, see the Cisco Crosswork Optimization Engine Function Packs document.
Cisco Crosswork Optimization Engine Architecture
In order to provide for better scalability and improved performance the data collection functionality has been separated out into its own VM and software package called Cisco Crosswork Data Gateway. The license to use Cisco Crosswork Data Gateway is included with the Crosswork Optimization Engine license. Cisco Crosswork Data Gateway gathers all the information from the monitored devices and forwards it to Crosswork Optimization Engine for analysis and processing. Crosswork Optimization Engine can then be used by the operator to manage the network or respond to changes in the network.
Apart from Crosswork Optimization Engine, Cisco Crosswork Data Gateway is required for external data collection, such as interface statistics via SNMP and model-driven telemetry sensor paths. Crosswork Optimization Engine can use Cisco Network Services Orchestrator (Cisco NSO) as a provider to manage the devices for any required model-driven telemetry (MDT) sensor paths for data collection. Cisco NSO then supplies the device management and configuration-maintenance services.
If you do not plan to use to use Cisco NSO, you must apply the telemetry configuration on your devices. See the "Prerequisites for Device Telemetry" topic in the Cisco Crosswork Optimization Engine User Guide.

Note |
Crosswork Optimization Engine is designed and tested to be used with the Cisco Crosswork Data Gateway 1.1 release. |
This guide explains the installation process to set up both Crosswork Optimization Engine and Cisco Crosswork Data Gateway for use. For information on how to use Crosswork Optimization Engine, refer to the Cisco Crosswork Optimization Engine User Guide.
