What is WAE ?• A model-driven path visibility and path

computation engine that can simulate, optimize and activate paths in the network supporting a multi-vendor and multi-layer environment

• Enables applications for planning, peering, forecasting, traffic engineering to be developed via a programmatic interface

• WAE is NOT a controller – but leverages controllers.

Key Use Cases

DEVNET-2035 7


Simulation and Impact Visualization Route Simulation Traffic Simulation

Determine how Demands and LSPs are routed taking into account network constraints

(MUST consider failure conditions)

Using the Routing Simulation, Determine the utilization of interfaces and SLA impact to traffic

(MUST consider failure conditions)

Simulate Link Failure See the Impact per Service Class

DEVNET-2035


Use Case: Evaluate Onboarding of a New Customer

Can a new service using 4Gbps at the San Francisco PoP be supported?

Model and predict impact of the new service within minutes

Identify flows for new customer Add 4Gbps to those flowsSimulate results

Scenario Value

DEVNET-2035


Use Case: Multi-layer Path DiversityObservations Analysis Recommendations

At Layer three LSP paths look disjoint

If a fiber cut happens, both tunnels go down

Account for L1 and L3 in the disjointness calculation

DEVNET-2035


Use Case: Optimization based on CapacityScenario Value

Ask WAE to find the minimum number of tunnels needed to get below a utilization threshold

Optimize the network to ensure it is not over-utilized

WAE Design functionality accessible through an API• Step 5: Deploy the model to the WAE Automation server

DEVNET-2035



WAE RPC API

WAE Design functionality accessible through an API• Step 6: Putting the functions together

The script will need as inputs the source node, destination node and a unique tunnel name.

Define the path on the system to store the source and destination network models.

Import Required Libraries

DEVNET-2035



WAE RPC API

WAE Design functionality accessible through an API• Step 6: Putting the functions together

Next download the plan file and load it in the WAE Design RPC API service

Create and Optimize the LSP

Save the plan file from the WAE Design RPC API to the file system, then deploy that plan file to the Automation server.

Save and Run the script
