We see there are multiple solution being discussed at IETF. BIER seems to be better fit the SR paradigm , what would be better fit for network ? Earlier majority of vendors were not supporting BIER due to hardware limitations , but now we see some vendors have started supporting BIER in documentation , what would be operators choice ?

I am sure this forum has many experienced network operator , they could provide some input.

By any chance, there is any comparison of these two technologies ? which makes life easy .
