Genius project provides Generic Network Interfaces, Utilities & Services. Any ODL application can use these to achieve interference-free co-existence with other applications using Genius. it provides following major modules -

Modules providing a common view of Network interfaces for different services

• Interface (logical port) Manager
  • Allows bindings/registration of multiple services to logical ports/interfaces
  • Ability to plugin different types of southbound protocol renderers
• Overlay Tunnel Manager
  • Creates and maintains overlay tunnels between configured TEPs

Modules providing commonly used functions as shared services to avoid duplication of code and waste of resources.

• Aliveness Monitor
  • Provides tunnel/nexthop aliveness monitoring services
• ID Manager
  • Generates persistent unique integer IDs for given key
• MD-SAL Utils
  • Provides common generic APIs for interaction with MD-SAL

In Oxygen cycle we have achieved following planned activities -

• Improved ITM Tunnel mesh scale (upto 150 DPNs)
  • TEP Interface to avoid creating tunnel interfaces in interface-manager, all the tunnel handling should be contained within ITM service
  • Selective BFD monitoring to selectively enable BFD monitoring using config knobs
  • Tunnel watch group support is use of tunnel group with watch-port set as the tunnel openflow-port
  • point-to-multipoint tunnel support Use of openflow-based-tunnels without tunnel-interfaces
• Other project improvements
  • Interface Manager and ITM integrated with infrautils S-n-D framework to publish their operational status.
  • Using new ManagedNewTransactionRunner utility everywhere there is a DataBroker
  • Using new FutureRpcResults utility in every RPC
  • Migrate all users of @Deprecated genius DJC to infrautils JC
  • Switch to using new infrautils Cache API instead of using ConcurrentMap
  • Migrate all users of @Deprecated Data Store Listeners to new ones
