Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco Crosswork Planning: Optimize Your Network Performance and Reliability
Cisco® Crosswork Planning empowers you to proactively manage your network infrastructure. It provides a comprehensive suite of tools for network discovery, analysis, simulation, and optimization. This data sheet outlines the key features and benefits of Crosswork Planning, helping you achieve:
● Improved Network Visibility: Gain a deep understanding of your network topology, traffic patterns, and health.
● Enhanced Reliability: Proactively identify potential network issues and optimize configurations for optimal performance under various failure scenarios.
● Streamlined Network Capacity Planning: Automate network planning tasks.
Key Crosswork Planning features
● Automated Network Discovery: Automatically discover multivendor, multiprotocol network devices, topology, and traffic statistics.
● Advanced Simulation and Modeling: Visualize and model network behavior under various conditions, including IGP, MPLS, Segment Routing, QoS, BGP, VPN, and Multicast.
● AI-Powered What-if Analysis: Predict network behavior in response to potential failures or changes using advanced "what-if" scenarios.
● Demand Deduction: Derive accurate end-to-end traffic flows from various sources for better capacity planning.
● Network Optimization Recommendations: Receive data-driven recommendations to optimize traffic flow, balance network load, and improve overall performance.
● Comprehensive Capacity Planning: Plan for future network demands with insights into network engineering, capacity needs, and traffic engineering strategies.
● Reduced Downtime: Proactive identification and mitigation of potential network issues.
● Improved Network Performance: Optimize traffic flow and network utilization for better user experience.
● Enhanced Network Reliability: Identify and mitigate network vulnerabilities.
● Capacity Planning Recommendations: Automate tasks and streamline network planning processes.
● Informed Decision Making: Gain data-driven insights to make strategic network investments.
Use Case Examples Using Predictive Analysis to Power AI Operations
Using a “What-if” scenario, Crosswork Planning predicts the utilization in the event of an object (SRLG, Circuit, Node) failure and how traffic would reroute.
In the following example, a demand (representing a traffic flow) from the Seattle region is observed, colored purple, and routed across the network to Houston. See Figure 1.
Demand between Seattle and Houston
In the event of a circuit failure, between Seattle and San Jose, the predicted reroute of the demand is shown. Observe the dotted line below in Figure 2.
Rerouted demand after a link failure
The Simulation Analysis tool combines the simulation results of a large set of failure scenarios. These results are useful for determining how vulnerable a network is to congestion and high latencies under failures, allowing you to plan sufficient capacity for any given failure scenario.
Simulation Analysis runs across a set of failure scenarios that can include selected objects, circuits, and traffic levels. Cisco Crosswork Planning calculates these failure scenarios across all service classes.
The “worst case” is the highest utilization that a particular interface experiences over all the failure sets and traffic levels you selected. Cisco Crosswork Planning determines which combination of failures would cause this worst-case utilization.
Using the Sample WAN.txt plan file in Figure 3 below, the “worst case” or simulation analysis of circuit failures is executed. Crosswork Planning returns the detailed results and views (Figure 4) of the analysis. Operators and planners can now review the results and take steps to mitigate each failure.
