[RPRWG] P802.17b D1_2 Multicast Conference Call Reminder



RPRWGers, 

A reminder that this Friday is a conference call to 
discuss multicast scoping in 802.17b.

Call starts at 9am (dial in 866-902-7862 ID 8021700).

During the past few weeks a few people have changed their
votes and the new results are shown below.

We are still slightly short of a decision on both
question. Thus, if people wish to change their votes based 
on reviewing the current results, they should contact me
immediately. 

As previously reported, there were 2 questions that did
not achieve a concensus view

----------------------------------------------------------

Question 3:
3)	Multicast scoping should have the following 
features. [Note: a, b, and c get a 2-address frame from the client (as
compared to d).]

a.	Scope basic frames without SAS learning
b.	Scope extended frames without SAS learning
c.	Scope extended frames with SAS learning
d.	Scope client frames with 4 addresses without SAS learning

The set of {a,b,c,d} has decreased to acceptable to 50% of voters 
(6 of 12) but had 5 negative votes for that option.

The set of {a,b,c} has increased to be acceptable to 66% of voters 
(8 of 12) but has 2 negative votes for that option.

Note that option {a,b,c} is now 1 vote away from being acceptable
to a 75% majority.

-----------------------------------------------------------

Question 6:

6)	Assuming it is done frame by frame, control over how a 
frame is processed is via:

a.	Client supplied request parameter(s)
b.	Configuration of the Multicast Table
c.	Both, client request takes priority
d.	Both, table takes priority

Option C has 8 votes or 72% support but 2 negative votes 
Option B has 7 votes or 63% support but 3 negative votes

Either of these options could go over the top, but clearly
C requires just 1 versus 2 more voter(s).

Because of the near loss on C the editor was instructed to 
prepare text (in editor's notes) assuming C was selected. The
text will not be an official part of the draft until it is
approved.


cheers, 

mike
