App SLA Assurance Enhancements

App SLA Assurance Enhancements
Measuring application performance and delivering App SLAs is a core component of Prisma SD-WAN. Performance Policy builds upon the existing App SLA configuration to deliver a policy framework for the measurement, enforcement, and alerts for application SLAs. With this release, the performance policy feature includes the following enhancements.
  • Packet Duplication
    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).
  • Service Health Probes
    Prisma SD-WAN now supports always-on probing to measure key metrics such as round trip latency, packet loss, and jitter to any ICMP/DNS/HTTP/HTTPS service across any transport (Direct, Fabric, Standard VPN). The results are available to the user and they can also be used to make path selection decisions with precise control using performance policy. Additionally, the same application health probes can be used by the system to determine the L3 Reachability.
  • Incidents for System & Site Health Metrics
    In addition to Incidents for link and application health metrics, Prisma SD-WAN now supports the ability to generate incidents for critical system metrics such as CPU Utilization, Memory Utilization, Disk Utilization, and Concurrent Flow table usage as well as Circuit Utilization.
