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 WAN Automation Engine (WAE) provides the tools for capacity planning, failure analysis, and traffic engineering, as well as analyzing network health and traffic trends.
Cisco® WAE is an integrated system for the designing, engineering, and planning of IP networks. It enables IT teams to explore the impact of failures and design changes on traffic flows, network performance, and reliability.
IP networks deliver a wide range of services, including cloud-based services, infrastructure as a service, unified communications and video collaboration services, and mobile services. With so many services dependent on this infrastructure, IT teams must focus on optimization of the network through capacity planning, traffic engineering, and improved network designs (greenfield or brownfield).
Cisco WAE meets these ongoing requirements through network planning and design tools that enable you to improve traffic distribution, identify vulnerabilities, and mitigate risk. Used worldwide by network planners and engineers, WAE’s streamlined workflow and highly interactive interface enables providers to accurately model the network and quickly accomplish planning tasks to improve network efficiency and operational costs (OpEx) under different network stress conditions.

Feature |
Benefit |
Collection |
Automated discovery of multivendor, multiprotocol network environments, including devices, topology, and traffic statistics. WAE continuously takes “snapshots” of the operating network and automatically adapts to changes without the need for user intervention to keep information current. |
Simulation and modeling |
Visualization of IGP , MPLS LDP, MPLS Segment routing, RSVP-TE LSPs, Segment Routing LSPs, QoS, BGP, VPN, Multicast, and Layer 1 networks |
Failure analysis |
Extensive reliability and resiliency analysis, including worst-case utilizations and latencies over a range of Layer 3 and Layer 1 failure states. |
Demand deduction |
Cisco-patented Demand Deduction derives highly accurate end-to-end traffic flows from any available source, including traffic polling and NetFlow data. |
Optimization |
Provide recommendations on LSPs and IGP metrics to balance traffic flow and optimize capacity |
Capacity planning |
Provides recommendations on all three facets of Capacity Management - Network Engineering, Capacity Planning and Traffic Engineering |
WAE Collector provides a continuous process of taking operating network snapshots to capture changes without the need for user intervention and keeping backup information current. The network discovery and data collection process generates files used by both WAE Design and WAE Live. These files can include network configuration, visual layout, LSP and multicast routes, operational state of network objects, infrastructure elements, topology, and traffic statistics for network planning and analytics.
● Comprehensive: Supports multiple vendors (including Cisco, Juniper, Alcatel-Lucent, Nokia, Huawei) and multiple data sources
● Versatile: Supports major IP/MPLS network protocols including OSPF (v2, v3), IS-IS, BGP, QoS, IP Multicast, RSVP-TE, Layer 2 and Layer 3 VPNs, and LDP
● High performance: Discovers network objects and collects data from large IP/MPLS networks in minutes
● Automated: Captures the network topology, state and measurement changes using a scheduled collection process, ensuring no disconnect between the real network and the visualized, analyzed, or planned network.
Create and edit plans, including using Layer 1 topology, to build cost-effective Layer 3 networks. You can evaluate requirements for fastest routes and resilient Layer 1 circuit routes with routing and disjointness constraints.
● Know traffic utilization along any path, visually indicating the severity of traffic demands at any point in the network
● Comprehensive network representation of network elements and their properties for realistic simulations
● Use the network map (see Figure 1) to automatically receive detailed information in a table below it or select information in the table and see it represented graphically in the map
● Simple object creation and manipulation, including assignment of properties, for realistic network simulations
● Multiple backgrounds, such as schematic and geographic, offering multiple views of the same network, from high-level representations to street details
● Customizable layouts that can be shared, minimizing the amount of time it takes to upgrade plans
● Tools for automating visualization tasks, such as assigning site locations based on longitude and latitude, aligning sites, and segregating edge devices

WAE Design capacity management
Network capacity planning shortens project cycles while enabling capital and operational cost savings. WAE Design helps you accurately build out your network to remove bandwidth bottlenecks and better assess current and future traffic plans to ensure network resiliency.
WAE Design tools simplify capacity planning by enabling you to quickly and precisely perform the following tasks.
● Identify how failures (see Figure 2) affect the network and where bottlenecks would occur
● Determine inbound and outbound traffic demands within a site and from site to site, minimum/maximum latency, and path metrics
● Create growth plans based on traffic trends
● Use Simulation Analysis with user-specified failure scenarios to isolate worst-case impact on traffic utilization and latency
● Drill down into a site to see exactly what traffic types (for example, video versus data) cause congestion on a specific link
Impact of failed link between WDC and NYC causes congestion on link to KCY
WAE Design traffic engineering
Optimize the infrastructure through traffic load balancing while detecting and solving shortcomings in resiliency.
● Balance traffic loads across the least expensive links
● Provides a step-by-step sequence of routing configuration changes to move a network safely from an initial configuration to a prespecified final configuration congruent with optimization goals
● Explore the impact of moving traffic from one circuit to another
● Automatically identify how to optimize IGP metrics, L1 link metrics, and LSP paths
● Identify the shortest paths based on lowest total IGP values and change IGP metrics to observe impact on routed traffic and any issue the change might cause
● Change BGP routing between multiple ASs to maintain network integrity and service levels
