Inter-Domain Peering Optimization

• Deployment Implications

  • Collection Nodes: Low/Moderate
  • Disk Usage: Low
    • Metrics include:
      • Time (how long do you keep the data?)
      • Interfaces (generally linear multiplier)
      • Flow diversity (hard question to answer)
      • Flow-export version
    • CPU: Low
      • Metrics include:
        • Interfaces (n x streams of flow data)
        • Flow diversity (hard question to answer)
        • BGP model (route-reflection scaling issues)
        • Flow-export version (5 vs. 8)
