I agree. As a point of reference, we've only have defined two IGP
algorithms so far and the segment routing draft dates back about 4
years.

Even with more artistic freedom afforded to multicast, I still
believe 256 standard algorithms are enough.

Guys,
I would think 8 bits are sufficient. Others (like SegRtg mentioned
below also use 8). 8 bits gives us tons of room to grow - especially
since we have only a single value defined currently (SFP 0). If we
have clear use cases that show us running out of 8 bits or getting
close to that we can/should discuss and evaluate extensions in light
of that but increasing the space "just in case" is not a prudent way
to go.

Hi Arkadiy,
I checked the latest
<draft-ietf-ospf-segment-routing-extensions-24> and
<draft-ietf-isis-segment-routing-extensions-15> for reference and
comparing, and they both use a 8 bits Algorithm.
One of the description: "Algorithm: Single octet identifying
the algorithm."
Interesting to use more than 8 bits for BIER's future
flexibility :-)

XieJingrong

Hello Working Group,
After initial discussions between multiple participants of the
working group, we consolidated that BIER's future flexibility would
be well served if we extend the IGP signaling BAR field to 16 bits.
We are currently reviewing various use-cases that can greatly
benefit from this enhancement.
I would appreciate if the proposed change could be considered
as part of IETF Last Call review.
Thanks,
Arkadiy
