Abstract: The emerging Software Defined Networking (SDN) paradigm is being adopted by the telecom industry since it enables flexible network resource allocation, configuration and management. Multicast is an essential and attractive service for a wide range of todays Internet applications for its bandwidth-preserving efficiency and flexibility. In a multicast, a data stream is delivered from single or multiple sources to a group of destinations simultaneously. SDN has potential to simplify multicast traffic engineering by leveraging the centralized nature of the network control plane, which provides a global view of the network that is built based on the real-time data gathered from network devices. Bit Indexed Explicit Replication (BIER) Multicasting is one of the recently devoloped multicasting applications that was proposed by the Internet Engineering Task Force (IETF). BIER architecture enables flexible and scalable multicast solution because it eliminates the need for using a protocol to explicitly build multicast distribution tree. Moreover, in BIER multicasting, intermediate network nodes will not need to maintain per-flow state or participate in routing decisions. The SDN controller will configure the source nodes to encapsulate multicast tree information in the packet header. After that, intermediate nodes will simply forward the packet according to the header.
