Performance Policy Use Cases

Introduction to Performance Policy use cases to review sample policy rules for several common use cases along with general guidelines for implementation.
Where Can I Use This?What Do I Need?
  • Prisma SD-WAN
  • Active Prisma SD-WAN license.
  • Physical and virtual ION devices running software version 6.3.1 and higher.
Performance Policy provides a flexible framework for the assurance of Application and Network SLAs. In this section, we will review common use cases, how to configure the policy intent, and how to monitor for effectiveness.
  • Use Case 1 - Protect a Business Critical SaaS Application: The business uses SuperSaaSApp as a critical application, requiring low latency and SLA compliance. Direct internet paths (Verizon and Comcast) are prioritized, with metered 5G as a fallback. A performance policy monitors path quality (latency, jitter, packet loss) and dynamically routes traffic to compliant paths, raising alerts for noncompliance. Monitoring tools like Flow Browser revealed Verizon's excessive packet loss, triggering incidents for degraded application and circuit performance. This policy ensures optimal app performance, efficient traffic management, and timely issue resolution.
  • Use Case 2 - Protect a Business Critical Enterprise Application: The business uses WebPoS for Point of Sale, hosted in corporate data centers, where packet loss significantly affects performance. A performance policy prioritizes the Prisma SD-WAN VPN on the primary internet, with metered 5G as a Layer 3 failure path. The policy uses Link Quality Monitoring (LQM) to adaptively apply Forward Error Correction (FEC) for packet loss, ensuring optimal performance. Monitoring tools revealed consistent packet loss on the active path, mitigated by FEC to maintain 0% packet loss for WebPoS sessions. This policy ensures reliable order processing and is easily monitored through Application Details, Link Quality Metrics, and the Flow Browser.
  • Use Case 3 - Protect Physical Security on LEO Satellite and 5G: The business relies on secure, high-bandwidth connectivity for remote locations with strict physical security requirements, including video and audio surveillance. Traffic is configured to use Prisma SD-WAN VPNs over LEO Satellite Internet and non-metered Public 5G as active paths, with Internet ADSL as a Layer 3 failure path. The performance policy leverages Link Quality Monitoring (LQM) to actively manage packet duplication during packet loss or path degradation, ensuring reliable operations. This setup ensures delivery of critical traffic, with issues monitored through App Site Details, Link Quality Metrics, and the Flow Browser.
  • Use Case 4 - Protect An Enterprise Voice Application: The business relies on a VoIP system for contact centers, with an SLA requiring a minimum MOS score of 3.6 and packet loss below 1%. Media traffic (RTP-Audio, RTP-Base, and SIP) uses primary internet and MPLS as active paths, with Metered 5G as a last-resort fallback. A performance policy ensures traffic is routed through SLA compliant paths, with packet duplication applied during packet loss or path degradation. This policy guarantees critical voice traffic delivery and is monitored via App Site Details, Link Quality Metrics, and the Flow Browser.
