Emerging Drivers for Adoption
  • Past
  • Focus was on infrastructure
  • Proprietary technologies
  • Performance demanded custom hardware
  • Little integration across technologies
  • Slower product cycles and competition
  • Enterprises unwilling to accept any risk in
    networking
  • Today
  • Infrastructure is in place
  • Interoperable standards
  • Moore's Law enables high performance via software
  • Shift to software-based applications/services
  • Increase competition among vendors
  • Vibrant open-source community embraced by
    enterprises looking for a better solution
