Re: [STDS-802-16] [MMR-AH-UM] Some comments for joint contributions of usage model
Hello Sungjin,
I don't know what exactly your point is.
If you have a chance to check the current 11s draft specs or ongoing
discussions there, some of the points raised by Jen-Shun and Saravanan
-- like the centralized control at the BS (the Root Mesh Portal in
case of 11s) and the availability of the whole topology information
there -- are also the case for the 11s system, although, as I
understand, there are still differences between the two.
Originally most of the 11s path selection protocols proposed were mere
adaptations or slight extensions of MANET routing protocols like AODV
and OLSR, but the whole discussions have been greatly changed once we
came to understand the differences between the IETF MANET and the IEEE
WLAN Mesh, esp. the importance of (Root) portals interfacing Mesh
networks to external ones.
As in some of the earlier discussions on this topic within 16j, the
current default path selection protocol for the 11s includes a quite
centralized, tree-based protocol where most of functionality and
information are put on the said Root mesh portal.
Anyhow, my point was that we better use or borrow from the existing
terminology to denote a similar/identical concept as much as possible.
Of course, if we see clear differences, we shouldn't hesitate to
create new one.
With Regards,
Joseph
