Internship Opening: Light, Efficient Multicast with B.I.E.R.

Light, Efficient Multicast with B.I.E.R. B.I.E.R. (Bit-Indexed Explicit Replication) is a multicast mechanism wherein the source of the multicast data packet (i.e. the ingress router which injects the multicast data packet into a B.I.E.R. domain) explicitly identifies and indicates (by…
