config system sdwan
    config zone
        edit "virtual-wan-link"
            set service-sla-fail-behavior maintain
        next
    end
    config members
        edit 1
            set interface "port1"
            set gateway 192.168.1.1
            set source 192.168.2.1
        next
        edit 2
            set interface "port2"
            set gateway 10.0.1.1
            set source 10.0.2.1
            set cost 10
        next
    end
    config health-check
        edit "Google"
            set server "google.com"
            set members 1 2
            config sla
                edit 1
                    set latency-threshold 150
                    set jitter-threshold 30
                    set packetloss-threshold 2
                next
            end
        next
    end
    config service
        edit 1
            set name "VoIP_Traffic"
            set mode priority
            set src "internal_subnet"
            set dst "SIP_Servers"
            set internet-service enable
            set internet-service-app-ctrl 34640

    // Correlate with historical incidents and resolutions
    const similarIncidents = knowledgeBase.findSimilarPatterns(anomalyDetection);
    
    // Generate recommended actions with confidence scores
    const recommendations = [];
    for (const incident of similarIncidents) {
        const confidence = calculateConfidence(incident, anomalyDetection);
        if (confidence > CONFIDENCE_THRESHOLD) {
            recommendations.push({
                action: incident.resolution,
                confidence: confidence,
                automatable: incident.resolution.canBeAutomated()
            });
        }
    }
    
    // Apply automated remediation for high-confidence actions
    const automatableActions = recommendations
        .filter(r => r.automatable && r.confidence > AUTO_REMEDIATION_THRESHOLD);
    
    if (automatableActions.length > 0) {
        const selectedAction = automatableActions[0];
        applyRemediation(branchId, selectedAction.action);
        logAutomatedAction(branchId, selectedAction);
    }
    
    return {
        analysis: anomalyDetection,
        recommendations: recommendations,
        automatedActions: automatableActions
    };
}

This pseudocode demonstrates how machine learning could be applied to automate complex troubleshooting tasks that currently require human expertise.
