Plan Your Network Using Cisco Optical Network Planner

This document provides instructions on how to deploy an NCS 1010 based network, using Cisco ONP, ZTP, and Cisco ONC. Cisco ONP helps with designing a topology with the required specifications, analyze it, and generate the planning data. ZTP, then sets up and brings up the devices. Cisco ONC uses the planning data from Cisco ONP to configure and manage the devices.

This chapter describes the Design and Analysis of Networks and how to Export Planning data from Cisco Optical Network Planner.

Plan Your Network

The following sections describe how to plan an NCS 1010 based network, using Cisco ONP. Cisco ONP helps with designing a topology with the required specifications, analyze it, and generate the planning data.

Reference Network Topology

The network topology that is shown in this section has been used to explain the NCS 1010 bring-up scenarios. It is a four-degree topology that uses 13 NCS 1010 nodes. The BRK-8 modules are used to create express interconnects among SITE-2, SITE-3, SITE-4, and SITE-5 using MPO cables.

Figure 1. Multi-degree Topology
This is a four degree topology that uses 13 NCS 1010 nodes.

Design the Topology Using Cisco ONP

Use the following steps to design the topology in Cisco ONP:

Procedure

Step 1

Log in to Cisco ONP Web Interface.

Step 2

Choose File > New.

The Create New Network dialog box appears.

Step 3

From the L0 Network Platform drop-down list, choose NCS1010.

Step 4

Click Create.

You can view the map and the design palette.

Step 5

Click the Drawing Tool icon (pencil and ruler crossed).

Step 6

Add sites to the map using the drawing tool.

  1. Zoom into the map to the desired level.

  2. Click any of the site icons (ROADM, OLA) and drag it to the sites on the map. Drag or click the map where a site has to be placed, when the cursor changes to the site icon.

    To create this topology:

    • Add four ROADM sites and name them as Site1, Site6, Site7, and Site8.

    • Set the site property, Structure as Terminal for all the sites.

    • Add five OLA sites as shown in the topology.

    • Add a ROADM site in the middle of the topology and name it as Multidegree.

  3. Click the Fiber icon and drag it to connect from one site to another site. Continue this for all sites.

    Note

     

    By default, the fiber length is updated as 1 km for all the fibers. If you want the length to be auto updated based on the x, y coordinates, then enable the Use Coordinates Distance property under the network Properties.

    Note

     

    In CONP topology, Site-2, Site-3, Site-4 and Site-5 are not separate nodes. These are all part of a single 4-degree node and represented as Sides of a 4-degree node. In case of NCS 1010, each side is considered as a device. After you connect the site with fiber, four sides are created. Rename the sides as Site-2, Site-3, Site-4, and Site-5.

Step 7

Set the properties of OLA nodes added in the topology to convert them into ILA- C, ILA-R-C, or ILA-2R-C nodes.

  1. Expand the OLA site in the network tree and drill-down until the C-band.

  2. Under the C-Band properties, choose Raman from the Raman Amp drop-down list.

  3. For ILA-2R-C, repeat steps B and C for another side under the site.

    To summarize:

    • ILA-C: No Raman is selected.

    • ILA-R-C: Raman is selected in one side.

    • ILA-2R-C: Raman is selected in two sides.

Step 8

Create circuits between Site-6 to Site-7, Multidegree Site to Site 6, and Site 1 to Site 8.

  1. Click the Drawing Tool icon, and select Circuit (purple in color).

  2. Add the circuit between the sites on the map.

Step 9

To add the MD-32-E and MD-32-O Mux/Demux patch panels, set the following properties:

  1. Choose Network > Entity Editor, and click the Service tab.

  2. In the left tree panel, expand the circuit connecting the site to which patch panel is connected, and drill-down to the trail properties.

  3. Under the trail properties, set the Add/Drop Type as Colored.

  4. Click Select Similar to apply the properties in bulk to all the trails.

  5. Click Update.

  6. Click the Site tab.

  7. Expand the site interface and drill-down to the Add/Drop properties of the side and set the Colored Add/Drop as MD-32-Even or MD-32-Odd as per the topology.

  8. Click Select Similar to apply the properties in bulk to all the add/drops.

  9. Click Update.

Step 10

To add BRK-24 and BRK-8 breakout panels, set the following properties:

  1. Choose Network > Entity Editor, and click the Service tab.

  2. In the left tree panel, expand the circuit connecting the site to which the breakout panel is connected, and drill-down to the trail properties.

  3. Under the trail properties, set the Add/Drop Type as Colorless.

  4. Click Select Similar to apply the properties in bulk to all the trails.

  5. Click Update.

  6. Click the Site tab.

  7. Expand the site interface and drill-down to the Add/Drop properties of the side and set the Colorless Add/Drop as BRK-8 or BRK-24as per the topology.

  8. Click Select Similar to apply the properties in bulk to all the add/drops.

  9. Click Update.

Step 11

To add NCS 1004 (1.2T card), set the following properties:

  1. Expand the circuit connecting the site to which NCS 1004 (1.2T card) is connected, in the left tree panel, and drill-down to the trail properties.

  2. Under the trail properties, set the Card Type as NCS1004_16QAM_400G_27%SDFEC_69GBd.

  3. Click Select Similar to apply the properties in bulk to all the trails.

  4. Click Update.

Step 12

To add 8201 (ZR+) pluggable, set the following properties:

  1. Expand the circuit connecting the site to which the 8201 (ZR+) pluggable is connected, in the left tree panel, and drill-down to the trail properties.

  2. Under the trail properties, set the Card Type as CFP2_400ZR+_TXP_GUA18_OFEC_15_DE_ON_16Q_OS_BR60_1.

    The topology looks like the following in the Cisco ONP UI.

Step 13

Choose File > Save As.

Step 14

Enter a network name in the Give a Network Name dialog box.

Step 15

Click Save.

Analyze the Network

Analyze the designed sample network to check the feasibility of the network using the following steps:

Procedure

Step 1

Log in to Cisco ONP Web Interface.

Step 2

Choose File > Open.

The Select Network To Open dialog box appears.

Step 3

Click the sample topology network that you have created, from the list of networks.

Step 4

Choose Network > Analyze.

The Cisco ONP analysis progress indicator indicates the analysis status.

If there is any failure in the analysis stage, a pop-up window appears with the message, “Analysis Failed.”

Step 5

Choose the Elements > Messages tab to see the list of error details in the analyzed network.

By default, it shows only the key messages when the Critical Only toggle button is enabled. If you want to view the entire network message, disable the Critical Only toggle button.

Step 6

If you find an error message under the Messages tab, resolve the error and analyze the network again. Repeat this step until all errors are resolved.
