4 Displaying Network Data

This chapter describes how data is displayed in Oracle Communications Network Intelligence.

About Displaying Network Data

Network Intelligence contains an application platform and data modeling database that provides visualization, utilization, and trending reporting on all network entity types from topologies, networks, equipment, equipment holders, and links, down to individual cards and trails.

By measuring and reporting the utilization of all network elements, and examining existing capacity utilization blackspots, Network Intelligence suggests the re-routing of inefficient trails, and generates comprehensive outage information. Optimal aggregation of all lower-order traffic to minimum higher-order links is provided with optimal routing of all higher-order and lower-order trails. You can map path to service resources and perform route analysis to check protection, physical separation, and resilience.

The network can be viewed from any of the following perspectives:

  • Topology

  • Network

  • Location

  • Equipment

  • Trail

  • Service

  • Customer

All tabular reports generated can be saved to spreadsheet, or HTML, format. All graphical views can be displayed as image files.

Filtering View Data

In Network intelligence, most reports use active filtering, where the items in the filter panel reflect only the data related to the entity being reported on.

For example, in a report detailing trails terminating on an equipment, the filter options offered (trail groups, capacities, and so on) are those that apply to trails that terminate on the equipment.

Some reports, for performance reasons, do not use active filtering. For example:

  • Network Node view

  • Network All Child Trails view

  • Site All Child Trails view

  • Topology All Child Trails view

  • Equipment All Child Trails view

Instead, these views are filtered to display a usable subset of the available data. For example, when displaying trails, you can select to display links or path trails, or you can display trails for a specific capacity. If you do not select any filter criteria, all data is displayed. However, in some cases, you cannot open a view without filtering.

Note:

Filter criteria change depending on the view.

To filter view data:

  1. Select a view. If the view allows filtering, the Filter Criteria tab is displayed.

  2. Use the tabs to display the type of data you want to filter from. For example, to display a specific type of trail, click Group Type.

  3. Select the properties you want to include in the view. For example, to include links, select Link.

    Properties in tabs are dependent on each other. For example, the type of trail you select in the Group Type tab determines the available capacities in the Capacity tab (for example, the filter is prepopulated with all available traffic types for the selected equipment based on the known list of trails that reference the equipment).

    The Traffic Type filter enables the selection of one, or both of, the following:

    • Terminating traffic only: trail traffic that has a start, or an end point associated with the selected entity (the entity is normally a equipment or site);

    • Transiting traffic only: trail traffic that passes through, but does not terminate on, the selected entity.

    If no filter options are selected, the filter returns a list of all trails that have any association with the entity.

  4. Display the view.

Refer to the Network Intelligence Help for further information on filtering.

Using Standard Trail View Filter Options

Links, or link trails, generally, are point-to-point links at the highest level of the logical network. Parents of links are normally cable fiber pairs. From a planning point of view, a link trail is considered a link with a capacity to be managed between two network nodes. Link trails transport child trails of group type Path.

Path trails normally refer to path trails that logically carry customer trails between two points in the network. Path trails have link trails as parents and child trails of group type Trail as children.

Circuit trails are circuits that deliver services to customer nodes. A circuit with a group type of Circuit normally has trails of group type Path as parents.

Note:

The names Link, Path, and Trail can be changed by an administrative user using the administrative web portal. For example, in the US a link is commonly called a facility and a path is usually known as a rider.

The standard filter options for trail views are:

  • Group Type:

    • Link

    • Circuit

    • Path

  • Group: Defines a set of trails that are of a common type within a group type. For example, you can define a Group with the name ”IP Link” that is a child of Group Type ”Link,” which enables the classification of all IP Link trails as part of the same group.

  • Service

  • Capacity

  • Date Range:

    • Creation date

    • In service date

Using Standard Link View Filter Options

The standard filter options for link views are:

  • Group Type:

    • Link

    • Circuit

    • Path

  • Group

  • Service

  • Capacity

  • Protection types:

    • Protected

    • Protection

    • Unprotected

Using Standard Equipment View Filter Options

The standard filter options for equipment views are:

  • Equipment Platform: Denotes the type of technology to which an equipment belongs (for example, IP, DWDM, SDH, Metro Ethernet).

  • Equipment Type: Sub-categorizes equipment within an equipment platform (for example, the equipment platform IP has two equipment types: IP Router and IP Switch).

  • Equipment Template: Defines the equipment model (for example, Cisco 8600 is the model type that identifies a particular equipment instance).

About Entity Type Trail Views

Certain views are common to some, or all, entity types.

There are two standard trail sub-views available for each entity type.

Terminating Child Trails View

The Terminating Child Trails view displays a list of all trails that have an end point associated with the entity (equipment, site, and so on).

By double-clicking any trail (row), you can view or edit that trail's details.

About the Terminating Child Trails View Data

The Terminating Child Trails view displays details about the trail name, the service applied to it, the associated capacity, whether it is structured or unstructured, the group type, and the planning status. It also displays the data defined in Table 4-1.

Table 4-1 Terminating Child Trails View Data Attributes

Attribute Definition

External Status

The status of the trail as described in the master inventory source.

Utilization percent

The amount of trail bandwidth used. For channelized trails, this is the number of channels consumed divided by the number of channels available.

Total Slots

For a channelized trail, this is the total number of slots (channels).

Free Slots

For a channelized trail, this is the total number of slots (channels) that are carrying no child trails.

Distance

The distance in kilometers (km). This is the total of each logical link site-to-site hop (link).

This value can be customized to reflect distance in miles.

Hops

The number of site-to-site hops (links) that the trail traverses.

Monthly Uptake

The average amount of trail bandwidth consumed each month.

Exhaustion Date

The predicted exhaustion date of the trail based on the monthly uptake.

Each time bandwidth is consumed, or freed up, this data is recalculated.

A Address

The location address of the start site entity that the trail references.

Z Address

The location address of the end site entity that the trail references.

OLO Label

An optional label used to describe the label or reference that the other licensed operator (OLO) uses to refer to this trail, if this trail is a leased trail.

Supplier Reference

An optional label to provide additional information to describe the trail.


All Child Trails View

The All Child Trails view displays a list of all trails that have an association with the selected entity. This includes all terminating trails: trails that have a start, or an end point associated with the selected entity, and all transiting trail: trails that pass through, but do not terminate on the selected entity.

To display a usable set of meaningful data, a standard trail search filter is available for this view.

See "Filtering View Data".

About Inter-Entity Mesh Views

An inter-entity mesh view, is a graphical representation of sites or equipment connected using links. Inter-entity mesh views include:

About the Inter Site Trail Mesh Report

The Inter Site Trail Mesh report is a graphical view displaying all the links between selected network sites.

The Inter Site Trail Mesh report can be filtered using the standard trail filter criteria (trail type, bandwidth, and so on). Filtering the selection of data generates a more meaningful report.

To run the report:

  1. Navigate to the site tree browser.

  2. Click the entity group view icon and select Inter Site Trail Mesh Report.

  3. Refine the data by doing any of the following:

Selecting Link Utilization Thresholds

Link utilization thresholds provide visual information in the mesh view about the cumulative utilization of links between sites.

For example, if you set a link threshold using the color red for any link greater than or equal to 70 percent, any link between two site entities that has a cumulative utilization of 88 percent is drawn in red on the mesh view.

Any link with a cumulative utilization less than the lowest set threshold is displayed in green. If no thresholds are set, all links are displayed in green.

Any link can be selected by placing the mouse over that link. If the mouse is over a link then the link color changes to blue and a label interactor is displayed at the top of the mesh view depicting the following data:

  • A Site Name-Z Site Name

  • Number of links

  • Cumulative utilization

Applying the Settings

After the filter criteria have been selected, you can display the following views:

  • Network view: displays the network.

  • Route Links view: displays mesh data in a table view. Each row represents a trail and consists of the following fields:

    • A Site

    • Z Site

    • Capacity

    • Service

    • Utilization %.

    • Total Slots

    • Used Slots

    • Monthly Uptake: The average amount of trail bandwidth consumed each month, this percentage is calculated for the list of trails that comprise the Route Links view.

    • Exhaustion Date: The predicted exhaustion date of the trail based on the monthly uptake. Each time bandwidth is consumed, or freed up, this data is recalculated. This value is calculated for the list of trails that comprise the Route Links view.

  • Trail List view: provides a table view of the trails between the sites and consists of the following fields:

    • Name

    • Service

About the Inter Site Pair Trail Mesh View

An Inter Site Pair Trail Mesh view is very similar to an Inter Site Trail Mesh report, except that you select site pairs in the network, rather than single sites.

For example, if a network has four sites A, B, C, D, choosing site pairs A-B and B-C displays traffic on the two chosen links. In a site mesh view, you select A, B, C, D, and all connecting links (if any) are displayed:

  • A-B

  • A-C

  • B-C

  • A-D, and so on.

Selecting a site mesh view is a means of filtering the mesh view so that only certain A-Z route links are looked at. Filtering the selection of data generates a more meaningful report.

To run the site pair mesh view:

  1. Navigate to the site tree browser.

  2. Click the entity group view icon and select Inter Site Pair Trail Mesh Report.

  3. Refine the data by doing any of the following:

Filtering Data

Before filtering data for this view, select originating and terminating site pairs, or originating and terminating location pairs. These pairs populate the filter for this view. Next, apply the standard trail search filter.

Refer to the Network Intelligence Help for further information on using the standard trail search filter.

About the Inter Equipment Trail Mesh Report

An inter equipment trail mesh report is a graphical report displaying all of the links for a chosen capacity between selected network equipment. Inter equipment mesh views are searchable using the standard trail filter criteria. The standard trail search filter is available for the Inter Equipment Mesh views. The report has the same behavior as the Inter Site Trail Mesh view, except that in this instance the nodes are equipment entities, and not site entities.

About the Inter Equipment Pair Trail Mesh View

An inter equipment pair trail mesh view is very similar to a inter equipment trail mesh view, except that you select equipment pairs in the network, rather than single equipment.

For example, if a network has four equipment, A, B, C, D, choosing site pairs A-B and B-C displays traffic on the two chosen links. In an equipment pair mesh report, you select A, B, C, D, and all connecting links (if any) would be displayed:

  • A-B

  • A-C

  • B-C

  • A-D, and so on

Selecting an equipment mesh view is a means of filtering the mesh view so that only certain A-Z route links are looked at.

To run the equipment pair mesh view:

  1. Navigate to the Equipment tree browser.

  2. Click the entity group view icon, and select Inter Equipment Pair Trail Mesh View.

    This view has the same behavior as the Inter Site Pair Trail Mesh view, except that in this instance the nodes are equipment entities, and not site entities.
