9 The technology of Bit Index Explicit Replication (BIER) specifies a new
10 architecture for the forwarding of multicast data packets. It provides
11 optimal forwarding of multicast data packets through a "multicast domain".
12 However, it does not require the use of a protocol for explicitly building
13 multicast distribution trees, and it does not require intermediate nodes
14 to maintain any per-flow state. See specific in `draft-ietf-bier-architecture-05
15 <https://datatracker.ietf.org/doc/draft-ietf-bier-architecture/>`_
16 and related documents.
18 The BIER project provides functionality about BIER topo-mamagement and BIER
19 channel-mamagement, and invoking south-bound-interface for device driver.
22 BIER User-Facing Features
23 -------------------------
26 - This feature contains all other features/bundles of BIER project. If you
27 install it, it provides all functions that the BIER project can support.
31 - This feature contains all models of BIER project, such as ietf-bier,
32 ietf-multicast-information and so on.
34 - **odl-bier-topomanager-ui**
36 - This feature can display bier-topo-manager's APIs on UIs
37 (odl-mdsal-apidocs and odl-dlux-yangui).
39 - **odl-bier-channel-ui**
41 - This feature can display bier-channel's APIs on UIs (odl-mdsal-apidocs
44 - **odl-bier-service**
46 - This feature provides function which processing the result of BIER
47 topo-mamager and BIER channel-manager, and invoking south-bound-interface
50 - **odl-bier-adapter**
52 - This feature provides adapter for different BIER south-bound NETCONF
53 interface, so all BFRs in BIER domain with different NETCONF
54 configuration interface, they can operate normally together.
58 - This feature is south-bound NETCONF interface for BIER, it has
59 implemented standard interface (ietf-bier). If your BFR's NETCONF
60 interface is Non-standard, you should add your own interface for driver.
66 Preparing for Installation
67 ~~~~~~~~~~~~~~~~~~~~~~~~~~
69 1. Forwarding devices must support the OpenFlow protocol, and already be
70 configured so that OpenDaylight can discover those devices via the :ref:`OpenFlow
71 Plugin <ofp-user-guide>`.
73 2. Forwarding devices must support BIER configuration via NETCONF, which has a
74 standard IETF YANG model.
80 Run OpenDaylight and install BIER Service *odl-bier-all* as below::
82 feature:install odl-bier-all
84 For a more detailed overview of the BIER, see the :ref:`bier-dev-guide`.
