In this scenario, the business uses a traditional VoIP system hosted in the corporate
data center for their customer contact centers. The business has an SLA with a
minimum acceptable MOS score of 3.6 and the packet loss cannot exceed 1% in either
direction for contact center media traffic which is detected as RTP-Audio, RTP-Base,
and SIP. There is a mix of internet and MPLS for active transport and Metered 5G as
a path of last resort, which will only be used for this traffic.
RTP-Audio, RTP-Base, and SIP are configured with these path policy rules:
- Active Paths:
- Prisma SD-WAN VPN on Primary Internet.
- Prisma SD-WAN VPN on MPLS.
- Backup Paths: None
- L3 Failure Paths: Prisma SD-WAN VPN on Metered 5G.
Performance Policy Intent
- Use one of the Active Paths as long as at least one path is MOS and Packet Loss SLA compliant.
- Use Link Quality Monitoring (LQM) information available from the Branch to Data Center VPNs to control Packet Duplication for any observed packet loss onto the active paths.
- If neither of the Active Paths are compliant with the packet loss SLA, then begin to duplicate packets on to each of the active paths.
- If one of the two Active Paths is down and the other is degraded, then perform single link packet duplication.
- Use the Metered 5G L3 Failure Path if all of the Active Paths are down (not degraded).
- If the Metered 5G path exceeds the loss, SLA tolerance then performs single link packet duplication.
Configure the Policy Rule
- Select the desired policy set from.ManagePrisma SD-WANPoliciesPerformance
- SelectAdd Ruleand enter theNameasProtect Voice Traffic,Description(optional), and theOrder Number(optional).More specific rules should be organized at the top of the Policy Set list, else a less specific policy rule may be matched first.
- In theActionssection, selectPacket DuplicationandMove Flows.
- In theMatch Criteriasection, underApp Filters, select the applicationsRTP-Base,RTP-Audio, andSIPfrom the drop-down, select the category inPath FiltersasPrimary InternetandMPLS. Select thePath TypeasPrisma SD-WAN VPN.
- In thePerformance SLAssection, clickAdd New, and check the optionLink Quality Metrics. Enter theSLA NameasVoice SLA.
- InLink Quality Metrics, enter theMOS(Mean Opinion Score) value as 3.6.This will use the best (highest) measured MOS value between the branch and all data centers on a per branch circuit basis.
- Click the+sign to enter thePacket Lossvalue as 1%.This will use the best (lowest) measured Packet Loss value between the branch and all data centers on a per branch circuit basis.
- Retain theAdvanced Settingsat their default values.
- Review theSummaryof the policy settings for the desired policy intent andSave & Exit.
Summary
: Implementing the Performance
Policy rule for the contact center media applications ensures the delivery of the
business critical traffic by finding MOS and Packet Loss SLA compliant paths and
mitigating any loss in the transport networks using packet duplication when necessary.
The impact of the rule is easily monitored using the App Site Details, Link Quality
Metrics, and Flow Browser.
