Re: RE: AD request / L2 Triggers Chapter Statement

Hi Aaron,

Quicky Answer:  No.

Long  winded answer:

Protocols for the Internet are not to be replaced but MAY surely be improved for
wireless devices right?  If you think so, you may agree some of the points A-F 
listed below.

If you don't agree; can you explain to me how QoS for wired/wireless links is going
to work properly without L2 trigger events providing feedback to/through IP?  
How about fast and seamless handovers for wireless devices to from other wired
and wireless devices.

Some points in order of dimishing IETF support (I think....)

A).  Wireless access to the global Internet is only going to grow (by any stretch of the 
       imagination). [most IETFrs will buy this]
B).  The physics of wireless links is different from that of fixed links.  It is different 
       enough to warrant at least some specialized treatment. [probably lose most the pilc 
       crowd here].
C).  To operate with satisfactory performance, in a variety of wireless settings, IP
       requires some fundamental improvement in implementation AND in standardization
       (probably spread out over quite a few SDOs)
D).  IP-over-everything should be qualified as: IP-over-everything wired (at least with
       the way things are now).
E).  TCP is currently broken for wireless (I know there is work on going).  UDP is not
       too much help.  SCTP improves certain things.  L2 triggers are a stepping stone
       toward fixing some of the problems by giving transport protocols visibility into
       fast changing L2 behavior, like link quality changes, link drops, etc.
F).  Wireless L2s share much commonality  with each other,  but not as much with fixed/
       wired links with respect to their real time behavior.
G).  L2 triggers are fundamental to fast/seamless/smooth/fluffy/soft IP layer handoffs.

Best regards,

Phil
