Re: research questions


Apart from looking at COPS-RSVP, I suggest you look at the SBM draft as well 
(RFC 2814). This is a standard mechanism for policy decision points (PDP's) to 
be "inserted" between RSVP clients and routers.

I'm not sure if Linux RSVP clients have SBM client support... I know Microsoft 
Win2K clients do, plus the Win2K server can function as a SBM.

There are a number of bit-fiddling questions which get debated on 
this newsgroup.  But one of the real-world problems is how to control 
QoS.  If everybody has the 'priority button' what's to keep them from 
all pushing it?  Leaving us back at the best-effort position we're at 
now.  There's language on bandwidth brokers in the IETF working group 
papers, but not much in way of implementation.  As a suggestion....
