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/BIER-TE topo-mamagement and BIER/BIER-TE
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-bierman**
36 - This feature generates BIER's topology from network topology, and configuration
37 of BIER, BIER-TE, etc.
39 - **odl-bier-channel**
41 - This feature provides function about multicast flow information configuration
42 and deployment in BIER domain.
44 - **odl-bier-service**
46 - This feature provides function which processing the result of BIER bierman and BIER
47 channel, and invoking south-bound-interface for driver.
49 - **odl-bier-adapter**
51 - This feature provides adapter for different BIER south-bound NETCONF
52 interfaces, so all BFRs in BIER domain with different NETCONF
53 configuration interfaces and they can operate normally together.
57 - This feature is south-bound NETCONF interface for BIER, it has implemented standard interface
58 (ietf-bier). If your BFR's NETCONF interface is Non-standard, you should add your own
63 - This feature provides path computation function for BIER-TE.
67 - This feature provides the interface of BIER management, which contain BIER/BIER-TE manager,
68 channel manager, topology manager.
74 Preparing for Installation
75 ~~~~~~~~~~~~~~~~~~~~~~~~~~
77 1. Forwarding devices must support the BGP-LS protocol, and already be
78 configured so that OpenDaylight can discover those devices.
80 2. Forwarding devices must support BIER configuration via NETCONF, which has a
81 standard IETF YANG model.
83 3. The feature *odl-bier-app* or third-party App provides the northbound interface
84 of BIER management for BIER controller.
90 Run OpenDaylight and install BIER Service *odl-bier-all* as below::
92 feature:install odl-bier-all
94 For a more detailed overview of the BIER, see the :ref:`bier-dev-guide`.
