12 Routing Trails

This section describes the Trail Routing Manager in Oracle Communications Network Intelligence. You can use the Trail Routing Manager to find the lowest-cost trail routing solution between two sites in the network. The suggested solutions offer optimal end-to-end trail paths to assist with network planning, service fulfillment, and service assurance.

Using Trail Routing Manager

To run Trail Routing Manager, perform one of the following:

  • Select Tools, then Trail Routing Manager

  • Click the Trail Routing Manager icon under the main menu on the Network Intelligence GUI:

    Trail Routing Manager icon

Using the Trail Routing Manager GUI

There are three main parts to the Trail Routing Manager GUI:

  • Service demand details area, where you complete the inputs required for the service demand.

    If used with the Trail Configuration Wizard, these details are automatically filled in using the values taken from the service demand input form in the Trail Configuration Wizard.

  • Service fulfilment analysis area, which lets you see what policy is set to determine path solutions. You can edit the policy, or select another policy here.

  • Routing solutions area, where you can examine suggested solutions that are suitable for the set of rules specified in the selected policy.

    Figure 12-1 shows the three main parts of the Trail Routing Manager GUI.

Defining Service Demands

The service demand details area is used to specify data that describes connection requirements for the service, such as the start and end site, and the capacity required.

A service demand is defined as a network requirement to route one or more trails between two network sites. To create a service demand you must supply the following data:

Table 12-1 Service Demand Data Definitions

Object Description

Start Site (A Site)

The network site where the trail connection originates.

You can enter the name of the site directly, or select the site using the search button.

End Site (Z Site)

The network site where the trail connection terminates.

You can enter the name of the site directly, or select the site using the search button.

Service

The service that the trail connection is transporting.

Capacity

The capacity or bandwidth required for the trail connection.

Customer

The customer that the service is required for.

No. of Trails

The total number of trail connections required.


Using the Service Policy

In Network Intelligence, service objects can have policy objects associated with them. Policies contain one or more constraint rules to apply conditions to the Trail Routing Manager's path analysis process when looking for path solutions for service demands.

Policies are not supplied with Network Intelligence. You create your own policies. Policies can only be created for service objects.

See "Using Services, Policies, and Rules" for a full explanation of service policies and rules.

Routing a Service Demand

To route a service demand, perform the following tasks:

  1. Do one of the following:

    • Select Tools, then Trail Routing Manager

    • Click the Trail Routing Manager icon:

      Trail Routing Manager icon

    Trail Routing Manager enables you to determine routes in ”study” mode, that is, to investigate routing possibilities for a particular service demand.

    Note:

    When invoking the Trail Routing Manager without a client like this, you are said to be in ”study” mode because in this mode you can see any available routing solutions but you cannot fulfil the service demand by creating actual trail objects.

    To create routed trail objects, use the Trail Configuration Wizard available in the Tools menu. The Trail Configuration Wizard takes you through a full set of simple tasks, including using the Trail Routing Manager to find a path.

  2. Enter your service demand by specifying the start and end sites for the service demand, the required service and capacity, the customer to whom the circuit applies, and the number of circuits needed.

  3. If a policy has been set for the service object, then the name of the policy is set in the policy field. If you have not set a policy for the service required, a No Policy set for Service message is displayed when you try to find path solutions.

    You must set a policy with some constraint rules for a service to find path solutions. The policy may be edited at any time by clicking View Policy and editing the policy.

    Note:

    The Trail Routing Manager is contained in a separate window to the main application. When you click View Policy, the policy object is displayed in a new tab in the workbench of the main application. You must switch context to select the main application to view the policy for editing.
  4. Click Analyze to start the path finding process. At this point, the service demand and its corresponding policy are sent to the Trail Routing Manager path analysis service to look for path solutions according to the constraint criteria defined in the rule set in the policy.

    Trail Routing Manager displays two separate views of the routing solution in the routing solutions view: one in graphical format, and the other in textual format.

Viewing a Routing Solution

To view a routing solution:

  1. Click one of the following tabs:

  2. To view any element in the solution, double-click that component of the routing solution in the Routing Solutions pane of Trail Routing Manager to view it in the Network Intelligence GUI. See "Viewing Elements of the Routing Solution".

  3. Modify the trail as required by clicking Edit, or select from the views associated with the trail by clicking the required view. See "Working with Trail Views".

    Figure 12-2 displays a graphical view of a routing solution.

    Figure 12-2 Trail Routing Manager: Routing Solution

    Description of Figure 12-2 follows
    Description of "Figure 12-2 Trail Routing Manager: Routing Solution"

Viewing Elements of the Routing Solution

You can also view any individual element from the route solution view; for example, drill down on the trail associated with the top solution by double-clicking it. This displays the trail object view that enables you to configure the trail or investigate the views associated with it.

Displaying the Textual View of the Routing Solution

Figure 12-3 displays a textual view of the same routing solution shown in Figure 12-2, outlining equipment and trails, the utilization percentage of each, and the number of channels and bandwidth available.

Figure 12-3 Routing Solution: Textual View

Description of Figure 12-3 follows
Description of "Figure 12-3 Routing Solution: Textual View"

Choosing the Routing Method

The suggested routing solution may offer options on how to perform the routing. This is denoted by the fact that the service demand is successful, but is marked by Select, as shown in Figure 12-4. In addition, the Accept button is disabled.

Figure 12-4 Selecting the Required Routing Method

Description of Figure 12-4 follows
Description of "Figure 12-4 Selecting the Required Routing Method"

To choose the routing method:

  1. Right-click Select to list the routing methods.

  2. Select from the suggested options:

    • Default configuration as main path

    • Manual configuration as main path

    • Default configuration as standby path

    • Manual configuration as standby path

    Manual configuration for routing over unstructured parent trails is different from that for structured parent trails:

    • When routing over unstructured trails, you do not need to select trail holders, so the trail holder selection dialog box is view only.

    • When routing over structured parent trails, you need to select parent timeslots.

  3. The Select label changes to Configured, and the Accept button at the base of the configuration screen is enabled.

  4. Click Accept to accept the path route solution, and write back the data to the Trail Configuration Wizard.

  5. Ensure the Routing Found check box is enabled when using the Trail Configuration Wizard. See "Creating a New Trail".

Applying Costs Using Trail Routing Manager

After you have generated a routing solution, you can use Trail Routing Manager to calculate the costs associated with this solution. The costing component of Trail Routing Manager enables you to set fixed and recurring total costs for the solution.

This section outlines the process of costing a solution by providing sample data:

Creating Tasks and Costs for Each Object

To generate costs for objects such as trails, connection, and port tasks, create individual tasks for each network build element in the routing solution. These tasks are referred to in Network Intelligence as build tasks,

For example, to create an equipment build task with the cost name 2Mb Unit Port, perform the following:

  1. From the top-level menu of the Network Intelligence GUI, select Administration, then select Costing, then select Maintain Equipment Build Tasks.

  2. Complete the task information:

    1. Enter the task name and the equipment supplier, and select the equipment definition. Any user-defined equipment definitions created are displayed in the list of available definitions.

    2. Select Add Equipment Costs to display the Equipment Cost List.

    3. Click Add Cost and enter the details for the task; for example: for Name, enter 2Mb Unit Port; for Expenditure Type, select CapEx; select Fixed Cost in the Fixed/Recurring field, and enter the required monetary amount under Amount.

  3. Click Save. The cost is displayed in the Equipment Cost List.

  4. Repeat for each equipment build cost.

  5. From the Equipment Cost List, select the costs required for the build, and click Select to transfer them to the equipment build task form. The total cost is automatically updated as each cost is added.

  6. Click Save. The cost is displayed in the Equipment Build Task List.

  7. Complete the task information outlined in the table for:

    • Trails

    • Connections.

Routing the Service Demand

To route the service demand, perform the following:

  1. In the Service Policy panel, click Route. The routing process may take some time, depending on the complexity of the demand.

  2. When Trail Routing Manager Status window returns the message Trail Routing Manager Processing Complete, click OK.

Inspecting the Routing Solutions

To inspect the routing solutions:

  1. In the Routing Solutions panel, click Solutions to view a graphical outline of the successful routing solution:
