SDN ????????????
  • ???????????????,?????????????????????????,????????
  • One Architecture fits all
  • Low utilization due to high active/passive
    redundancy
  • Mostly manual control
  • Specialized hardware
  • Completely closed system

SDN Value Proposition
  • Lower the cost of expensive network components
  • Fully utilize existing equipment (virtual
    networks, route traffic to network components,
    etc).
  • Create virtual routers, firewalls, IP VPNs, load
    balancers, network monitoring, etc,

Improve CAPEX
  • Provision network at a larger scale (system
    level)
  • Network operations are more self-serve and
    automated
  • Adjust traffic flows dynamically to reduce cost
  • Example Reduce power, Fully utilize WAN links

Lower OPEX
  • Quickly/automatically add/remove/changes
  • Examples Provision network around security
    services based on new or time based workloads or
    VM movement Segment network to provide highly
    secure multi-tenant services

Network Agility

Open Networking Foundation (ONF)
  • Open Networking Foundation (ONF) is a user-driven
    organization dedicated to the promotion and
    adoption of Software-Defined Networking (SDN)
    through open standards development.
  • ONF emphasizes an open, collaborative development
    process that is driven from the end-user
    perspective.
  • The OpenFlow Standard is the first SDN standard
    and a vital element of an open software-defined
    network architecture.
  • Our signature accomplishment to date is
    introducing the OpenFlow Standard, which enables
    remote programming of the forwarding plane.
  • Today, our working groups continue to analyze SDN
    requirements, evolve the OpenFlow Standard to
    address the needs of commercial deployments, and
    research new standards to expand SDN benefits.
