Add Multiple Demands

You can add multiple demands at a time to perform a what-if analysis of traffic flow in the network.

To add multiple demands:

  1. Select Network > Topology.
    The Topology page is displayed with the topology map at the center and the network information table at the bottom of the page.
  2. In the Demand tab, select Add > Multiple Demands.
    The Add Multiple Demands page appears on the right side of the page.
  3. Configure the demand parameters as explained in Table 1.
    Note:

    Fields marked with an asterisk (*) are mandatory.

  4. Click Add.
    A confirmation message appears on the top of the page, indicating that the add multiple demands request is sent successfully. You can then view the new demands in the Demand tab of the network information table.

Field Description
Properties
ID Prefix

Specify the prefix that is automatically added to the names of the demands.

For example, if you specify the ID prefix as xyz, the demand name is assigned as xyz_Node A_Node Z.

Node A List From the list, select one or more ingress (source) nodes of the demand. To select all the ingress nodes, select Select All.

To create meshed demands, you must specify the same nodes for Node A and Node Z by clicking the Copy Node Z List link. All the nodes that you specify in the Node Z List are added to the Node A List.

Node Z List From the list, select one or more egress (destination) nodes of the demand. To select all the egress nodes, select Select All.

To create meshed demands, you must specify the same nodes for Node A and Node Z by clicking the Copy Node A List link. All the nodes that you specify in the Node A List are added to the Node Z List.

Planned Bandwidth

Specify the planned bandwidth (along with valid units, with no space between the bandwidth and units) for the demands.

If you specify a value without units, bps is applied.

Valid units are:

  • B or b (bps)
  • M or m (Mbps)
  • K or k (Kbps)
  • G or g (Gbps)
Setup

Specify the setup priority for the demands.

Priority levels range from 0 (highest priority) through 7 (lowest priority), which is the default.

Based on the setup priority, the PCE determines whether a new demand can be established, by preempting an existing demand. The existing demand can be preempted if the setup priority of the new demand is higher than that of the existing demand and the preemption releases enough bandwidth for the new demand.

Hold

Specify the hold priority for the demands.

Priority levels range from 0 (highest priority) through 7 (lowest priority), which is the default.

Based on the hold priority, the PCE determines whether the demand can be preempted or not. If the hold priority for a demand is higher, the demand may not be preempted.
