Re: [Bier] Deborah Brungard's Block on charter-ietf-bier-01-06: (with BLOCK)

Hi Alia,

This looks good- just slight tweak:
 * teas on control-plane mechnisms to use BIER-TE forwarding mechanisms.
/s/
 * teas on architecture and control-plane mechanisms to use BIER-TE forwarding mechanisms.

Thanks-
Deborah

Hi Deborah,

How about instead of:

OLD
  8) BIER Traffic Engineering: Definition of an architecture, and
       specification of the associated technology, for a BIER-based
       mechanism to support traffic engineering."

NEW
  9) Forwarding Plane Mechanisms for BIER Traffic Engineering: definition of
      how the new BIER forwarding plane structures (e.g. BIFT) can be used to
      support engineered multicast trees.  No control-plane work will be done in BIER-WG.

and the WGs to coordinate with will have added:

 * teas on control-plane mechnisms to use BIER-TE forwarding mechanisms.

Regards,
Alia

BLOCK:

While a Discuss, this should be simple to address as I think it's a bit of a misnomer
which Alvaro has already noted.
About:
"8) BIER Traffic Engineering: Definition of an architecture, and
   specification of the associated technology, for a BIER-based
   mechanism to support traffic engineering."

Looking at the wg draft (which it seems this new charter item is based on),
the draft says:
"It does support traffic engineering by explicit hop-by-hop forwarding"
and "it is more similar to SR than RSVP-TE".

So it is not TE, it is explicit forwarding. As Alvaro noted, this should not
be identified in the charter as TE. I don't see any need for this new item to
be in the charter (as Alvaro noted).

This is a Discuss because if this is not a simple misnomer, then this work
clashes with TEAS. TEAS is chartered and responsible for "Traffic-engineering
architectures for generic applicability across packet and non-packet networks.
This includes both networks that include the use of PCE and those that do not."
