How to Calculate Remote Network Bandwidth
This section applies only to deployments where
you allocate bandwidth
by remote network location. To plan your bandwidth if you allocate bandwidth
by compute location, or for upgrade considerations when migrating
to allocating bandwidth by compute location, see Plan to Deploy Remote Networks.
When you onboard a remote network, it is important to specify
the correct remote network connection bandwidth that meets the needs
of your organization.
The number you specify for the bandwidth applies to both the
egress and ingress traffic for the remote network connection. If
you specify a bandwidth of 50 Mbps, Prisma Access provides you with
a remote network connection with 50 Mbps of bandwidth on ingress
and 50 Mbps on egress. Your bandwidth speeds can go up to 10% over
the specified amount without traffic being dropped; for a 50 Mbps connection,
the maximum bandwidth allocation is 55 Mbps on ingress and 55 Mbps on
egress (50 Mbps plus 10% overage allocation).
If you have an asymmetric internet connection, you should consider
your organization’s requirements to determine the bandwidth to specify.
Use the following graphic and examples to size your remote network
connection.
- Site A has a 100 Mbps connection both upstream and downstream. For this site, specify a remote network connection of 100 Mbps.
- Site B has an asymmetric connection, with 100 Mbps upstream and 25 Mbps downstream, and you want to make sure that the remote network connection does not throttle the upstream traffic. In this case, specify a remote network connection of 100 Mbps.
- Site C has an asymmetric connection, with 25 Mbps upstream and 100 Mbps downstream. For this site, you want to make sure that the remote network connection does not throttle the upstream traffic, but throttling the downstream traffic is acceptable. In this case, you can specify a remote network connection of 25 Mbps, which ensures that Prisma Access delivers 25 Mbps reliably in both directions.
