Abstract:
Methods, network devices and computer readable media are disclosed for replication and switching of Internet Protocol (IP) packets in professional media networks. In one embodiment, a method includes receiving, at a first node in a network configured for bit indexed explicit replication (BIER), and via a replication fabric within the network, a packet comprising a packet bit array. Each receiver of a plurality of non-BIER-enabled receivers reachable via the replication fabric is represented by a relative bit position in the packet bit array, and a respective IP address is assigned to each receiver. The method further includes determining that an intended non-BIER-enabled receiver of the packet is a local receiver of the first node, obtaining the IP address assigned to the local receiver, removing the packet bit array from the packet and forwarding the packet, without the packet bit array, to the local receiver via unicast IP forwarding.
