Performing RWA

This subsection describes how to perform RWA on a network. Following are the steps to perform RWA:

1. To perform RWA on a network, click on New Task; a new form will appear.

   Following are the available parameters of a form:

   

   • Assign name of the task: Provide name for the task.
   • Select the Network: The drop-down lists the loaded network which have been defined as part of the topology step, and the user should select the network over which the routing and wavelength assignment has to be done.
   • Select the Configuration: Select the network configuration with respect to the selected network.
2. Click on Submit, below page will be displayed.
3. Click on Dashboard, this redirects to the Home page.
4. RWA task will be created under Recent Tasks column in Home page.

   

5. Once the RWA task is completed (100 percent.) Click on Completed Task button and list of all completed tasks appears.

   

   Table showing list of all completed tasks. Following are the columns:

   • Sl No: Serial number is used to enumerate list of completed tasks.
   • Task Name: Displays the task name.
   • Task Started On: Displays the starting time of the task.
