Hi,
Thanks Brian for the
info.
I just want to know that if I have a dscp code mapping to a
strict priority queueing with a MF classifier will suffice a rfc 2474 compliant
diffserv.
Im new to this diffserv mailing and sorry for the trouble if
Im askin some absurd question.
Pl do throw light on this.
Thanks
Vidya
Vidya,
1.
We are working to set up a diffserv implementors' list where this kind of
topic
will be the main subject. Here, we develop the standards. However,
since that
list does not yet exist...
2. It depends what you mean
by minimal. If you are satisfied with the Class Selector
PHBs, all you
have to do is implement RFC 2474. In a host, this is a pretty small,
possibly null, change to an existing RFC 791 implementation. If you want
to support
the AF or EF PHBs, you also have to implement RFC 2597 and
2598.
3. RSVP and Diffserv can simply co-exist, or they can
interwork. For simple
coexistence, you don't have to do anything. For
interworking, there are
proposals in the ISSLL working group that have
not yet been standardized
(although they have been implemented in at
least one operating system).
For all of the above, it is really
desirable for the server to support traffic shaping.
It is more or less
useless for a server to request QOS (either by using RSVP/IntServ
or
Diffserv) without shaping the outgoing traffic stream. Also, of
course,
it's useless unless your network infrastructure and ISP support
QOS.

Thanks in advance.
