Network Browser Window

 

In the NorthStar Planner window, navigate to File > Open Network Browser to display the Network Browser window as shown in Figure 1.

When a network model is saved, it is available in the Network Browser window. Each network model is uniquely identified in the Network Browser by its directory path and runcode. The Network Browser also provides additional details for each network project such as the last modified date and time, descriptive comments about the network, and user-defined labels. A label can be applied to one or more networks. Labels and Comments are added to the model when you save it from the File menu.

In the list of models, there is a selection called Latest Network Archive. This model comes from the last Network Archive collection task you ran in the NorthStar Controller web UI. See Collection Tasks to Create Network Archives in the NorthStar Controller User Guide for information on running Network Archive collection and the option to archive the results.

There is also a selection called Live Network Snapshot. This model is a snapshot of the Live Network Model at the time you load it from the Network Browser. It reflects the most recent state of the Live Network.

The Latest Network Archive is generally preferable for planning purposes because it is more robust (BGP neighbors, static routing table, multicast, and so on). The Live Network Snapshot only includes information related to the MPLS TE domain, but is generally preferable for troubleshooting purposes because it is more current. Table 1 compares these two models.

Table 1: Live Network Snapshot versus Latest Network Archive

Live Network Snapshot

Latest Network Archive

How it is created?

Created when you open the LiveNetwork model in the NorthStar Planner. It represents the live network’s current state at that time.

Created when you run the Network Archive collection task in the NorthStar Controller. Might not be current when you access it in the NorthStar Planner.

What is included?

Includes only information related to the MPLS TE domain (exactly the same network as in the live network).

Includes information beyond MPLS TE domain such as BGP relationships, static routing table, multicast, pseudo-nodes (Ethernet), class of service–discovered from the .

Are historical versions available?

Not available: live network snapshot is on-demand only.

Latest Network Archive models are stored and available from the Network Browser under the Archives tab.

Tunnel design attributes that are configured in the NorthStar Controller are inherited by the NorthStar Planner, even though they are never pushed to the router. When you run Network Archive device collection in the Controller, the tunnel information in the Planner (which came from the router) is merged with the tunnel information in the Controller (which includes design attributes that are not pushed to the router). The merged version is then available in the Planner via both the Latest Network Archive and the Live Network Snapshot.

The following design attributes that are configured in the NorthStar Controller are inherited by the Planner via network archive collection:

  • Advanced tab: Symmetric Pair Group, Diversity Group, Diversity Level

  • Design tab: Routing Method, Max Delay, Max Hop, Max Cost

  • Scheduling tab: all scheduling information

In the Network Browser, you can filter the network models in the list by selecting a label from the Labels list in the left pane. You can also filter by typing a string in the Search Network box and clicking the magnifying glass icon.

The following actions can be performed in the Network Browser window by selecting a network model and right-clicking to open a menu:

  • To open a network model from the list, double-click an entry from the table or right-click and select Load.

  • To delete a network project, right-click an entry in the table and click Delete.

    Note

    The Delete option is not available for the Live Network Snapshot or the Latest Network Archive.

  • To refresh a model, right-click an entry and select Refresh. .
