[RPRWG] Concerns about 802.17b ideas.

Hi all,

I have read the recent 802.17 group meeting presentations about 802.17b.

Here I bring out two concerns.
(1) How dos SAS layer solve the persistent flooding at bridged 802.3 network problem, which is specified by 802.17-2004 standard's annex F.1.4.2.1?
      The recent presentations seemed not care about it, except for http://www.ieee802.org/17/documents/presentations/oct2004/ng_SR_01.pdf page 4. I think the incomplete learning issue is the same as persistent flooding issue.

(2) Why SAS aware station can not do SAB update(learning) for remote frames sent by non-SAS station?
      Alough http://www.ieee802.org/17/documents/presentations/nov2004/rc_SASehb_01.pdf page 3 gave an example for why, but I think this example is not convincing.
      Because the persistent flooding is also exist when do learning between two SAS aware stations.

Would any experts be kind to make clear explaination about these two issues?
