Add new node

Click on Node Information to view node information. Following are the steps to add new node:

1. Click on Add New Node button which is at top-right corner; a new form is shown to add node information.
2. Following are the form parameters:
   • Node Name: Provide simple and unique alphanumeric name.
   • Node Type: Provide one of the supported node types: ROADM, FOADM, ILA and GTN.
   • Node Design: Provide one of the abbreviations for the node design:

     A for Directional

     D for Directionless

     CD for Colorless-Directionless

     CA for Colorless-Directional

     CDC for Colorless-Directionless-Contentionless

     FOADM: For Fixed-Optical-Add-Drop-Multiplexer.

   • No of Wavelength: MDU Wavelength size that should be supported by the node.
   • Max Node Degree: Provide Maximum Node Degree.
   • Attenuation for GTN: Provide attenuation.
   • Exclusion Type: Provide Include or Path Exclude or Exclude.

     NOTE: All the parameters can be overwritten by the application, if user selects the wrong type of node.

     If more than 8 lambda originating from node, then that node considered as ROADM node with directionless solution.

Edit node information

Click on Edit button of the corresponding node to edit the node information. Fill the form and click on Submit to save data.

Delete node

Click on Delete button of the corresponding node to delete the node.

Add new link

Click on Topology tab to view topology information. Following are the steps to add new link:

1. Click on Add New Link button which is at the top-right corner; a new form is shown to add link information.
2. Following are the form parameters:
   • Source: Provide source node name, that is the node from where service is originating. DWDM services are carried over two fibers and therefore bidirectional. For downstream traffic source node will be the node where the lambda will be originating. For upstream traffic source node will be the node where the lambda will be terminating.
   • Destination: Provide destination node name, that is the node where service should terminate.
   • Distance (km): Displays distance between the nodes in kilometers.
   • Link: Link name, must be unique between two nodes. It is used to identify multiple links between two nodes. Unique name can be given to each link also.
   • Fiber Type: G.652, G.653, G.654, G.655-TW and G.655-LEAF types are supported.
   • Loss (in dB): Measured loss in dB.
   • Number of Connectors: Provide number of connectors.
   • Number of Splices: Provide number of splices.
   • Uplink Loss: Provide uplink loss in dB.
   • Downlink loss: Provide downlink loss in dB.
   • Place Raman Amplifier on Link: Enable the check box if the Raman amplifier is required or Disable the check box if the Raman amplifier is not required.
   • Exclusion Type: Provide Include, Path Exclude, Exclude.

     NOTE: Links with more than 60 dB loss cannot be designed by the APT application.

Edit link or edge information

Click on Edit button of the corresponding link to edit the link information. Fill the form and click on Submit to save data.

Delete link or edge

Click on Delete button of the corresponding link to delete the link.

Add SRLG information

Click on SRLG Info button of the corresponding link to view the SRLG information. Click on Add SRLG button and select the links part of the SRLG and save the data.

Add new service

Click on Service Matrix tab to view services information. Following are the steps to add new service:

1. Click on Add New Service button which is at the top-right corner; a new form is shown to add link information.
2. Following are the form parameters:
   • Source: Source node name, that is the node from where service is originating.
   • Destination: Provides destination node name, that is the node where service should terminate.
   • Service ID: Unique Service ID for each service.
   • Quantity: Provide integer value to duplicate service.
   • Line Side Traffic: Line side traffic can be 10, 100-600 in steps of 100. Auto can be given as input.
   • Client Side Traffic: User can add multiple client types in the form m*datatype1+n*datatype2. For example, 10x10GE+2x100GE (Refer to page 21 Client Rate).
   • Modulation: Select the modulation for the line side traffic (refer to figure Line Rate and Modulation Type, page number 21 for compatible Line rates and modulation types).
   • FEC type: Provide FEC type.
   • Is regen required: Enable check box if regen required or Disable check box if regen not required.
   • Regenerations: Provide number of regeneration.
   • Path Protection Type: Following Protection modes are supported:

     - 1: This stands for work path which would have been provisioned, where only one path is available for the service to flow, if the work path fails then another protection or restoration path will not be provided. Provide Protection Design as WSON or NA when protection is 1.

     – 1+R: Work and restoration path (Reuse of Lambda). Provide Protection Design as WSON.

     - 1+1: This stands for both Work and protected path which would have been provisioned. If work path fails, then the service which is owing through work path is routed to protected path. If the protected path fails, then another path will not be provided.

     – 1+1+R: Work, protect and restoration path. Network design simulation and restoration are possible. Provide Protection Design as WSON.

     – 1+1+F: Should have work and protect path forever. Provide Protection Design as WSON.

     – 1+1+1: This stands for work and two protected paths which would have been provisioned. If work path fails, then the service which is flowing through work path is routed to one of the protected path. If the protected path fails, then service which is flowing through one of the protected path is routed through another protected path, if the second protected path also fails, then another path will not be provided.

     NOTE: Options 1+1+R and 1+1+1 are for future use.

   • Protection Design: Available options are DWDM, WSON.
   • Service Protection Type: Provide service protection type.
   • Wavelength: If you do not know, add NA or leave blank. Wavelength number must be Tejas supported lambda number.
   • OSNR paths: Provide OSNR paths.
   • Destination List: Provide destination list .
   • Estimate Line Rate and Modulation Type: This box should be checked if line rate and modulation type are set to auto.
