Prisma SD-WAN console provides the aggregate link quality
metrics of all branch and data center sites at a glance.
Prisma SD-WAN allows network administrators
to meet their application Service Level Agreements (SLAs) with its
policies. Through the Prisma
SD-WAN path policy, you can define rules to express business intent
for which paths are allowed per application. The ION devices evaluate
each application session against the defined path policy and select
the WAN path that meets the application-specific SLA. One of the
many mechanisms used to determine if a path will meet an application’s
SLA is monitoring the
Prisma SD-WAN determines link quality by actively probing the
paths over public and private transports
and the private WAN underlay paths. The probes provide a constant
measurement of network performance metrics, such as jitter, latency,
and packet loss. These metrics, along with application-specific
performance metrics and Layer 1 – Layer 7 reachability inform traffic
forwarding decisions for new and existing application flows.
The Dashboard on
the Prisma SD-WAN web interface provides the aggregate link quality
metrics of all branch and data center sites at a glance. It includes
information on the MOS, packet loss, jitter, and latency of the
links. View data in the last available 5 minutes' time frames and
the last available 1 hour of any metric.
path selection for all real-time voice and video applications. If
a link is considered acceptable, the real-time application will
stay on the initially selected path. Still, when the link is degraded
or considered inadequate, the ION device will seamlessly move all
existing and subsequent real-time application flows to a suitable
alternate path as allowed by policy, if available.
