Network Switching

  • Traditional networks:
  • Decentralised switches with data plane and control plane on same device
  • Is OpenFlow the saviour?
  • Centralised managed controller
  • OpenFlow data plane switches
  • Potential to …
  • Automate configuration
  • Improve network efficiency
  • Reduce TCO

Network headaches

Ugh: plumbing!

  • Static/inflexible
  • Homogeneous/closed
  • Unvirtualized
  • Labour-intensive
  • Error-prone
  • Point Band-Aids
  • 10/100Gbps
  • Hyperscale DCs, IPv6
