Experimenting with bit index explicit replication

Bit Index Explicit Replication (BIER) is a recent multicast architecture that solves several problems with deployed IP multicast protocols. BIER embeds an implicit multicast tree representation inside each transmitted packet. With this new mechanism, it becomes possible to reconsider multicast applications. However, no open-source implementation of BIER can be found. This paper presents our open-source implementation of the BIER forwarding mechanism and a companion socket-like API. Additionally, we show simulations of the implementation with ns-3 DCE.
