Link Quality
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 Path
, QoS
,
and Security
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 Link Quality
.Prisma SD-WAN
determines link quality by actively probing the Secure
Fabric VPN
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.By default,
Link Quality
metrics influence
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.
