摘要
In an embodiment, a data processing method comprises receiving, at a BIER replicator node that is programmed to implement Bit Index Explicit Replication (BIER) protocol, from a data source, a multicast stream packet identifying a service-level multicast group address; using the BIER replicator node, replicating the multicast stream packet according to BIER protocol and transmitting two or more replicated packet streams to two or more BIER receiver nodes that are programmed to implement BIER; using the two or more BIER receiver nodes, transmitting the two or more replicated packet streams to two or more receivers. Other embodiments may use modified iOAM (In-situ Operations, Administration, and Maintenance) techniques comprising: using the source, encapsulating an iOAM header and placing in the header one of: an identifier of a replicator policy; a definition of a replicator policy expressed in a symbolic language; receiving the iOAM header at one or more of the BIER replicator nodes; at a particular one of the replicator nodes, performing one of: reading the identifier of the replicator policy, retrieving a pre-defined packet replication policy that matches the identifier, and executing the pre-defined packet replication policy to dynamically adjust packet processing behavior of the particular one of the BIER replicator nodes; or parsing the definition of the replicator policy in the symbolic language to yield a new packet replication policy, and executing the new packet replication policy to dynamically adjust packet processing behavior of the particular one of the BIER replicator nodes.
