      • SLAs that deliver end-to-end performance matching the requirements for voice, video, and data over converged business and residential networks
      • Provisioning via SLAs that provide end-to-end performance based on CIR, frame loss, delay, and delay variation characteristics
    • Service management requirements
      • The ability to monitor, diagnose, and centrally manage the network, using standards-based vendor independent implementations
      • Rapid service provisioning
  • 11. Agenda
