Prisma SD-WAN Performance Policy

Performance Policy utilizes link quality metrics such as Latency, Loss, and Jitter and application performance metrics such as Application RTT and Init failure % as SLA metrics.

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 alerting for application SLAs.

Performance Policy utilizes link quality metrics such as Latency, Loss, and Jitter as well as application performance metrics such as Application RTT and Init failure % as SLA metrics. If the SLA metrics are violated, the system takes action to ensure that the SLA is enforced including moving flows to a compliant path (if available) and invoking line conditioning such as Forward Error Correction (FEC)
to ensure the SLA is met. Optionally, an incident can be generated for critical applications when an SLA is violated. Although default policies work well for most environments, policies can be granularly tuned per application, path type, DC group, and circuit category to align to the performance needs of the business.

The minimum ION device software version required is 6.3.1 and later.
