In addition to Forward Error
Correction, Prisma SD-WAN now supports replication of an application session
across up to three VPN paths simultaneously, ensuring consistent and
optimized application experiences for end users.
Packet Duplication assures the
delivery of packets for critical applications, even when all underlay paths
are degraded beyond application SLA. Packet Duplication is configured in the
performance policy, where it is an additional action within the policy,
selectable on a per-app and/or per-path basis. Leveraging this capability
requires explicit selection of all paths onto which packets will be
duplicated (secondary/alternate paths) and duplicated by the (primary
path).
