5 Using Topologies

This section describes topologies in Oracle Communications Network Intelligence.

Using the Topology Tree Browser

The topology tree browser displays all topologies modeled in Network Intelligence, and is divided into subfolders for service topologies and resource topologies, with topologies listed alphabetically.

A service topology is used to model multipoint services in Network Intelligence; it is made up of the interconnection of the links and nodes of one of the following:

  • A point-to-point service;

  • A multipoint-to-multipoint service;

  • A rooted-multipoint service.

A resource topology is typically used to divide a network into logical groupings; for example: to partition a network into nodes and edges.

Each individual topology has two subfolders, as shown in Figure 5-1:

  • Links (containing the associated trails of all the topology links)

  • Nodes (containing the associated equipment of all the topology nodes)

Figure 5-1 Topology Tree Browser

Description of Figure 5-1 follows
Description of "Figure 5-1 Topology Tree Browser"

Topologies are either created in Network Intelligence, or loaded from the inventory management system:

  • Resource topologies are created in the Network Intelligence GUI. See "Creating a Resource Topology".

  • Service topologies are loaded from the inventory management system (IMS) in which they are modeled. See Network Intelligence Concepts for further information on data loading.

Creating a Resource Topology

You can create a resource topology using the Network Intelligence GUI.

To create a topology:

  1. Click Topology on the context toolbar.

  2. Click the Create icon:

    Create icon

    The New Resource Topology window is displayed.

  3. Configure the topology using the following values:

    • Topology Name: The name of the topology. The name must be unique.

    • Usage: Specifies the required usage; that is, whether the topology is of type Resource or Service. You may not edit this field.

    • Alias: (Optional) Provide another name for the topology.

    • Topology Pattern: Select the pattern to represent the topology:

      • Ring

      • Mesh

    • Topology Behavior: Select the topology behavior, that is, whether this is a routable topology, or is used for reporting and visualization purposes.

    • Network: Select the network associated with the topology.

    • Protection Type: Filter out protection trails that are not required in this topology by selecting from:

      • Protected

      • Protection

      • Unprotected

    • Type: (Optional): Specify the type.

    • Supplier: (Optional) Specify the supplier.

    • OutService Date: (Optional) Select the date on which the topology goes out of service.

    • Status: The status of the topology. The status is ONI Planned (where ONI signifies Oracle Communications Network Intelligence) by default.

  4. Click Save.

    To perform actions on a resource topology; for example: adding a link, or deleting a main node, and so on, see "Using the Link View".

Working with Topology Object Views

Topology object views vary depending on topology type; that is, whether the topology object is a resource topology or a service topology. See the following topics:

Working with Resource Topology Object Views

The topology object offers the following views for resource topologies:

  • Utilization View

  • Link View

  • Path View

  • To Other Resource Topologies Network View

  • To Other Resource Topology Nodes Network View

  • Terminating Child Trails View

  • All Child Trails View

Working with Service Topology Object Views

The topology object offers the following views for service topologies:

  • Utilization View

  • Terminating Child Trails View

  • All Child Trails View

Using the Utilization View

This view displays the utilization of the selected topology in terms of path, link, and equipment utilization.

  • Link utilization:

    Each link is defined by name and equipment pair. Utilization is described by carrying traffic, utilization percentage, the number of used channels, the number of free channels, the monthly utilization growth measured in megabytes, the date at which the link entered service, and the date of exhaustion for the link.

    For further information on path and link definitions, see "Using Standard Trail View Filter Options".

  • Path utilization:

    Each path is defined by name and equipment pair. Utilization is described by carrying traffic, utilization percentage, the number of used channels, the number of free channels, the monthly utilization growth measured in megabytes, the date at which the path entered service, and the date of exhaustion for the path.

    For further information on path and link definitions, see "Using Standard Trail View Filter Options".

  • Equipment access slot utilization:

    Each equipment is defined by name and capacity. Utilization is described by the number of free slots, and the total number of slots.

  • Equipment access port utilization:

    Each equipment is defined by name, supported card type, and port definition. Utilization is described by the total number of ports, the number of in-service ports, the number of planned ports, and the number of free ports.

Saving the Utilization View

To save a utilization view in CSV (comma-delimited value) format:

  1. Click Save As.

  2. Select a location to save the file.

Using the Link View

The Link View displays the topology nodes and their trail connections of type link in logical view format. The view displays all topology equipment (both main and access) and all of the links that connect them.

Path Core Links

Path core links are all path circuits that exist between a selected main node and all other main nodes in a topology.

Path Edge Links

Path edge links are all path circuits that exist between a selected main node and all other nodes that are not main nodes in this topology; for example: the other node may be an access node in this topology.

To configure the topology using the Link View, see the following sections:

Displaying Trails in a Link

To display the trails that comprise a link view:

  • Use the mouse to hover over a link in the Link View.

    The color of the link changes. A tooltip displays information about the link, in terms of name, associated service, capacity, total slots, free slots, and utilization.

  • Double-click a a link in the Link View.

    A table describing the trail in terms of name, associated service, capacity, group, status, protection, total slots, free slots, utilization, and so on, is displayed.

    Double-click a trail entry in the table to:

    • Display a detailed view of the trail.

    • Edit the trail.

    • Delete the trail.

Hiding the Link or Node Layer

By default, the Link View displays both the node layer and the link layer. You can turn off a layer so that only the other layer is visible.

To turn off the link layer, for example:

  1. Right-click in the background of the view, and click Layers.

  2. Uncheck Display Link Layer.

Adding a Main Node to a Topology

You can add a main node, that is, any equipment in the Network Intelligence GUI, to a topology in the Link View.

To add a main node:

  1. Right-click in the background of the view, and click Add Main Node to display the Add Main Node to Resource Topology window.

  2. Select a node (equipment) from the tree browser by dragging and dropping it on the window.

    Note:

    You can select nodes from either the Topology tree browser, or the Equipment tree browser. You can add multiple nodes.
  3. Click Apply.

Removing a Main Node from a Topology

In the link view, if a main node is removed, this removes all links to this node, both main links and path links. It also removes any access node on the other end of the link.

You can remove a main node, that is, any equipment in the Network Intelligence GUI, from a topology in the Link View.

To remove a main node:

  1. Right-click a node in the topology, and select Remove Node.

  2. Click OK to confirm the removal of the node, and its associated links and edge nodes, from the topology.

Adding a Link to a Topology

You can add a link to a topology from a main node.You cannot add a link from an access node.

To add a link to a topology:

  1. Right-click a main node, and click Add Link to display the Add Link to Topology window.

  2. Select a link (edge or core) from the list of available links by double-clicking it, and click Add Core Link or Add Edge Link to add it to the topology.

Removing a Link from a Topology

If all links between a main node and an access node are removed in the link view of a topology, this in turn deletes all access links and transport links to this node, and deletes the access node.

If all links between a main node and another main node are removed, this removes all links (both main links and path links).

To remove a link from a topology:

  1. Right-click a link, and click Remove Link(s).

  2. A warning dialog box may be displayed; for example: The selected access link and its associated edge node will be removed from the topology.

  3. Click OK to accept the removal of the link and its associated entities, if any, or click Cancel to close the window without making any modifications.

Saving a Topology View

You can configure the topology in the Link View by moving nodes using the left mouse key. You can then save individual topology link views for each topology and load them at a later point.

To save the currently displayed view:

  1. Click Save Topology Layout.

  2. Name the report.

  3. Save the report.

Loading a Topology View

To load a saved topology layout:

  1. Click Load Topology Layout.

  2. Select the report to display.

Using the Path View

The path view displays a logical view of all trails of type ”path”, and depicts the start and end nodes of all trails that appear on that topology.

The main links on the path view are the path circuits that exist between the selected node and all other main nodes in this topology, where an existing topology link exists between this node and the other main node in the topology.

The access links on the path view are the path circuits that exist between a selected main node and all other nodes that are not main nodes in this topology, where an existing path topology link exists between a selected main node and the other node; for example: the other node may be an access node in this topology.

The path view has the same behavior as the link view except that the trail selection criteria are based on transport path trails rather than link trails.

To configure the topology using the path view, see "Using the Link View".

Removing Links

In the path view, if all links between a main node and an access node are removed, then this deletes all path links.

Removing Nodes

In the path view, if a main node is removed, this removes all links to this node, both main links and path links. It also removes any access node on other end of link.

If an access node is removed, this removes all links to this node, both main links and path links. It also removes any access node on the other end of the link.

Using the To Other Resource Topologies Network View

The To Other Resource Topologies Network View displays how the topology is connected to other network topologies. The To Other Resource Topologies Network View allows filtering using the standard trail search filter.

To filter the view:
