Why XML? It is not too much readable and writable (by human) format.
It is human readable and very portable.

Hi Todd,
It is LWG. MgtWG will also be involved.
I am a member of IBTA however I have not noticed this discussion on
the IBTA

Hi All
Please find the attached RFC describing how QoS policy support could be
implemented in the OpenFabrics stack.

High-level feedback:
- An IB fabric could be used for a single ULP and still require
QoS. The issue is how to differentiate flows on a given shared
element within the fabric.
- QoS controls must be dynamic. The document references initialization as

Hi Todd,
While using the Service ID is an interesting idea, the problem is the
Service ID values
are not well defined by IBTA. Rather each endpoint is permitted to
define its own,
potentially transient set of Service ID values. The Service ID values
are discovered via

[EZ] Well, I agree with you but already got so many requests for XML
that I could not resists. Maybe we could do both.
