With the Prisma Access for Networks Aggregate
Bandwidth model, bandwidth is assigned to a compute region within
Panorama. This allows for deterministic placement of nodes and also
the compute for the nodes behind a region.
Within the Remote Networks Bandwidth Allocation in Panorama,
regions are configured for bandwidth that is to be allocated for
that region:
If looking at 2 locations, namely US East (purple box), and Europe
Central (orange box), you can see the respective bandwidth allocated
for each region as shown below.
With Prisma Access for Networks utilizing the Aggregate Bandwidth
model, for every 500 Mbps of bandwidth allocation, a compute instance
will be added to support the throughput requirements.
The compute instances behind a region are called the IPSec Termination
Nodes, and appear when configuring a Remote Network onboarding in
Panorama.
Given the above example, the number of nodes allocated would
be as follows:
