# Network Optimization

## 5G Integration

### Network Slicing Configuration

```yaml
apiVersion: networking.k8s.io/v1alpha1
kind: NetworkSlice
metadata:
  name: low-latency-slice
spec:
  priority: high
  qos:
    latency: "10ms"
    bandwidth: "1Gbps"
  isolation:
    type: "dedicated"
  endpoints:
    - selector:
        matchLabels:
          app: real-time-processing
```

## Edge Load Balancing

### Cilium Configuration

```yaml
apiVersion: cilium.io/v2
kind: CiliumNetworkPolicy
metadata:
  name: edge-loadbalancer
spec:
  endpointSelector:
    matchLabels:
      app: edge-service
  ingress:
  - fromEndpoints:
    - matchLabels:
        io.kubernetes.pod.namespace: edge
    toPorts:
    - ports:
      - port: "80"
        protocol: TCP
      rules:
        http:
        - method: "GET"
          path: "/api/v1/"
```

## Bandwidth Optimization

### Service Mesh Configuration

```yaml
apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: edge-circuit-breaker
spec:
  host: edge-service
  trafficPolicy:
    outlierDetection:
      consecutive5xxErrors: 5
      interval: 10s
      baseEjectionTime: 30s
    connectionPool:
      tcp:
        maxConnections: 100
      http:
        http2MaxRequests: 1000
        maxRequestsPerConnection: 10
```

## Best Practices

1. **Network Architecture**
   * Edge caching
   * Local DNS
   * Traffic shaping
   * QoS policies
2. **Performance Tuning**
   * Protocol optimization
   * Connection pooling
   * Request coalescing
   * Compression
3. **Monitoring**
   * Latency tracking
   * Bandwidth usage
   * Error rates
   * Network topology
4. **Security**
   * Network isolation
   * Traffic encryption
   * Access control
   * DDoS protection
