• Service binding data model used to bind a service on a particular interface
• Service module configures following parameters
  • Service-Priority
  • Service-Name
  • Service-Type
  • Service-Info
    • (for service-type openflow-based)
    • Flow-priority
    • Instruction-list
• Interface Manager maintains a Service dispatcher table to regulate pipeline dynamically between services
• Listens to service-binding changes and accordingly programs the dataplane (Table 0 & Service Dispatcher)

Making SBI protocol agnostic (South bound renderers)

• Provide a flexible way to support multiple south bound protocols
• North-bound interface/data-model is decoupled from south bound plugins
• NBI Data change listeners select and interact with appropriate SBI renderers
• New renderers can be added to support new Southbound interfaces/protocols/plugins
• Needs to be re-concilied with Netvirt re-design proposal
