Item

Description

Protocols

Displays the network by protocol.

Types

Display or label certain categories of nodes (for example, by hardware type) and links (for example, by trunk type).

Routing Instances

Displays routing instances/OSPF process IDs associated with each link/interface by the color in the legend. Customize the color by right-clicking to display the pop-up menu and selecting Set Color....

Advanced

Includes options to hide certain elements such as nodes within an autonomous system (AS) or links with low utilization.

Note

Selecting Filters>Protocols, Filters>Routing Instances, or Filters>Types displays the same information as selecting Subview>Protocols, Subview>Routing Instances, or Subview>Types.

The Network Elements are used to change what is displayed in the topology map. Table 2 lists the elements available in the topology map window.

Elements

Description

Nodes

Displays a list of the nodes in your network. Clicking a node highlights it on the map.

Links

Displays a list of links for the selected subview. Clicking a link highlights it on the map.

Facilities

Displays a list of facilities in the network. A facility is a set of nodes and links that are likely to fail together.

The Utilization Legends are used to display traffic in the topology map. Table 3 lists the utilization items available in the left pane of the topology map window.

Table 3: Left Pane Utilization Legends in the Topology Map Window

Item

Description

Utilization

Displays the planned link utilization using colors of the color bar. Planned utilization is the percentage of the link used by the demands you input into the network.

Peak Util

The Peak Util display feature is used after running a failure simulation script to view the highest (or worst case) link utilization loading experienced by each link, depending on the rerouting of demand/flow traffic after any single failure.

Planned Node Load

Displays the planned traffic on a node by a color bar. For further information.

Measured Node Load

Displays the measured interface traffic on a node by a color bar.

Measured Link Util

Displays the measured interface traffic load by CoS, as an alternative to Traffic > Traffic Load, with Interface selected (top menu bar).

Demand CoS Util

Displays the normal and peak utilization calculated based on demand routing, as an alternative to Traffic > Traffic Load.

The Subviews are used to display specific segments of the network in the topology map. Table 4 lists the subview items available in the left pane of the topology map window.

Protocols

Allows you to view your network by protocol.

P2MP

Displays a list of the P2MP tunnels in the network model. Click on a tunnel in the list to highlight the corresponding connections on the topology map. The Legend at the bottom of the window indicates how senders and receivers are represented on the map.

Routing Instances

Displays routing instances/OSPF process IDs associated with each link/interface according to the color in the legend. Customize the color by right-clicking to display the pop-up menu and selecting Set Color....

Types

Displays types of nodes and links (for example, by trunk type). Customize the color by right-clicking to display the pop-up menu and selecting Set Color....

Vendors

Displays link vendors using colors or line styles. Possible values for vendors include those that are specific to a certain country or region, and are listed in the tariff database. If a vendor is not specified, the vendor is set to the default DEF. To represent in-house fiber links with zero cost, the vendor should be set to NET. The color and style of these links can be customized by right-clicking on the icon in the left pane and selecting Set Color or Set Line Style.
