BIER User Guide¶

Overview¶

The technology of Bit Index Explicit Replication (BIER) specifies a new architecture for the forwarding of multicast data packets. It provides optimal forwarding of multicast data packets through a “multicast domain”. However, it does not require the use of a protocol for explicitly building multicast distribution trees, and it does not require intermediate nodes to maintain any per-flow state. See specific in draft-ietf-bier-architecture-05 and related documents.

The BIER project provides functionality about BIER topo-mamagement and BIER channel-mamagement, and invoking south-bound-interface for device driver.

BIER User-Facing Features¶

• odl-bier-all
  • This feature contains all other features/bundles of BIER project. If you install it, it provides all functions that the BIER project can support.
• odl-bier-models
  • This feature contains all models of BIER project, such as ietf-bier, ietf-multicast-information and so on.
• odl-bier-topomanager-ui
  • This feature can display bier-topo-manager’s APIs on UIs (odl-mdsal-apidocs and odl-dluxapps-yangui).
• odl-bier-channel-ui
  • This feature can display bier-channel’s APIs on UIs (odl-mdsal-apidocs and odl-dluxapps-yangui).
• odl-bier-service
  • This feature provides function which processing the result of BIER topo-mamager and BIER channel-manager, and invoking south-bound-interface for driver.
• odl-bier-adapter
  • This feature provides adapter for different BIER south-bound NETCONF interface, so all BFRs in BIER domain with different NETCONF configuration interface, they can operate normally together.
• odl-bier-driver
  • This feature is south-bound NETCONF interface for BIER, it has implemented standard interface (ietf-bier). If your BFR’s NETCONF interface is Non-standard, you should add your own interface for driver.
