Bit Index Explicit Replication (BIER) multicasting in transport networks

Live events and high quality video delivery are pushing the introduction of dynamic multicasting solutions. In this paper we discuss the most recent technologies enabling effective multicasting in packet and optical transport networks. In particular, both pointto-multi-point (P2MP) optical coherent technology as well as the newly proposed Bit Index Explicit Replication (BIER) packet technology are presented. Experimental demonstrations on both technologies are then reported, showing the effective capability to flexibly and dynamically configuring P2MP communications.
