Aggregate Demands/Tunnels


The Aggregate Demands feature is accessible through Network > Elements > Demands. Right-click on a demand and select Aggregate Demands. For each pair of nodes A and Z in the network, the Aggregate Demands function adds up the total bandwidth of all the demands starting at originating nodes A and destination nodes Z. Aggregate Demands then presents a table with one row for each node pair, showing A, Z, and the total bandwidth. The demands are sorted by bandwidth, the largest at the top.


For MPLS-enabled networks, there is a similar Aggregate Tunnels feature, accessible by selecting Network > Elements > Tunnels. Right-click on a tunnel and select Aggregate Tunnels. While reading this section, simply replace each occurrence of “demand” with “tunnel”.

A license for tunnels is required to access the Aggreg Tunnels feature.



Combine A-Z with Z-A

When this option is checked, the row for A-Z includes the demands from Z to A as well as A to Z. If it is not checked, there is one row for A-Z and one for Z-A.

Place demands only

When this option is checked, Aggregate Demands will only add up demands that have been placed by the program in the current network model.

Show at most

A network can have hundreds of thousands of node pairs. This option lets you see a manageable number of the heaviest pairs of nodes.

After specifying the Aggregate Demands parameters, the aggregated demand bandwidth is presented in a table form.

  • Highlight All: This function highlights all node pairs in this table on the topology map.

  • Report: This function saves the aggregate demands in a report on the server and client machines.
