7 The technology of Bit Index Explicit Replication (BIER) specifies a new
8 architecture for the forwarding of multicast data packets. It provides
9 optimal forwarding of multicast data packets through a "multicast domain".
10 However, it does not require the use of a protocol for explicitly building
11 multicast distribution trees, and it does not require intermediate nodes
12 to maintain any per-flow state. See specific in `draft-ietf-bier-architecture-05
13 <https://datatracker.ietf.org/doc/draft-ietf-bier-architecture/>`_
14 and related documents.
16 The BIER project provides functionality about BIER topo-mamagement and BIER
17 channel-mamagement, and invoking south-bound-interface for device driver.
20 BIER User-Facing Features
21 -------------------------
24 - This feature contains all other features/bundles of BIER project. If you
25 install it, it provides all functions that the BIER project can support.
29 - This feature contains all models of BIER project, such as ietf-bier,
30 ietf-multicast-information and so on.
32 - **odl-bier-topomanager-ui**
34 - This feature can display bier-topo-manager's APIs on UIs
35 (odl-mdsal-apidocs and odl-dlux-yangui).
37 - **odl-bier-channel-ui**
39 - This feature can display bier-channel's APIs on UIs (odl-mdsal-apidocs
42 - **odl-bier-service**
44 - This feature provides function which processing the result of BIER
45 topo-mamager and BIER channel-manager, and invoking south-bound-interface
48 - **odl-bier-adapter**
50 - This feature provides adapter for different BIER south-bound NETCONF
51 interface, so all BFRs in BIER domain with different NETCONF
52 configuration interface, they can operate normally together.
56 - This feature is south-bound NETCONF interface for BIER, it has
57 implemented standard interface (ietf-bier). If your BFR's NETCONF
58 interface is Non-standard, you should add your own interface for driver.
64 Preparing for Installation
65 ~~~~~~~~~~~~~~~~~~~~~~~~~~
67 1. Forwarding devices must support the OpenFlow protocol, and already be
68 configured so that OpenDaylight can discover those devices via the :ref:`OpenFlow
69 Plugin <ofp-user-guide>`.
71 2. Forwarding devices must support BIER configuration via NETCONF, which has a
72 standard IETF YANG model.
78 Run OpenDaylight and install BIER Service *odl-bier-all* as below::
80 feature:install odl-bier-all
82 For a more detailed overview of the BIER, see the :ref:`bier-dev-guide`.
