View WSON result

This section describes results of WSON. Following are the steps to view the WSON results:

1. To view WSON result click on the Result button.
2. Following are the tabs within the WSON result page:
   • Network Map: Shows the network map along with number of lambda passing through the link and also services on the right hand side of the window. To view utilization of node or link hover the mouse on node or link.

     

   • Hover the mouse on a node, pop-up will appear showing necessary details about the node as shown. The pop-up will display the following information:

     - Node Name: Displays node name.

     - Node Type: Displays type of the node, for example: ROADM or FOADM or ILA – Node Utilization Displays percentage of node utilization.

     - Service Flowing: Displays the per-service graph data of all the services present in the network.

     - Node Design: Displays design type of the node, for example: FOADM/ILA/A(Directional)/D(Directionless)/CD(Colourless Directionless)/CA(Colourless Directional)/CDC(Colourless Directionless Contentionless).

     

   • Hover the mouse on link, pop-up will appear showing necessary details about the link as shown. The pop-up will display the following information:

     - Link Name: Displays node name.

     - Distance: Displays Link name - Length of the link - Fiber type of the link.

     - Services Flowing: Displays all the services flowing on the link in the OSNR graph data.

     

3. Following are the steps to simulate network:
   • Select a service present on right hand side, path taken by the service will be shown. Example: select S1 service, a path taken by S1 service will be shown
   • Fail a link (click on particular link) from a path taken by the service, select the type of disjointness (node and link disjoint, fully and maximally disjoint)required, click on Run button present on right hand side. Affected services and new path will be displayed.

     

   • Explanation of options present in Network map page:

     - Affected Services: The list of services that changed their paths on current failure of a link/node.

     - No of reroute paths: The maximum no of restoration paths that services can have. For example if its value is 2 and service is 1+R (then it will have 2 restoration paths and 3 total paths). If its value is 2 and service is 1+1+R(then it will have 2 restoration paths and 4 total paths).

     - Following are the Disjointness condition:

     - Link disjoint: The disjoint services(mentioned in excel sheet or topology, this is called service pairing in wson) should not have any link in common.

     - Node disjoint: The disjoint services should not have any node in common.

     - SRLG disjoint: The SRLG links of the services should not be same.

     - Following are the Disjointness severity:

     - Fully disjoint: Show only if services are fully disjoint(no link/node in common).

     - Maximally disjoint: Show paths for services such that the least no of nodes/links are in common. The worst case can be the same path for both the services

     - Following are the Paths sorting condition:

     - Available wavelength: The path with the wavelength satisfying the disjoint condition will be taken first.

     - Hop count: The path with least no of hop counts will be taken.

     - Distance: The path with least total distance will be taken first.

4. SRLG: SRLG with respect to each service will be displayed if any.

   

5. One Two Three Cut Not Out: Click on One Two Three Cut Not Out tab, following page will be displayed.
