Hi All
Here some comments and some questions about the QoS-NSLP Qspec Template
draft.
In the introduction of the draft the Service Schedule is mentioned as a
QoS Description parameter, after in section 3.4 it is mentioned as a QSM
Specific Control Information and finally in section 3.5 it is placed in
the table of QoS description parameter as a QoS Desired and not detailed
in the remaining of the section like the other parameters : I want to know
if Service Schedule is at the same time QSM Control Information and a QoS
Description, in that case how it will be interpreted in the QNE?

My second question concenrs the function or the entity wich specifies the
parameters of Qspec in the QNI : Once an application triggers the QoS NSLP
to make a resource reservation, how the Qspec, wich is opaque to the
QoS-NSLP, is initially determinated in the QNI (by wich function in the
QNE is it made and fixed) so that it's QoS description parameters will be
interpreted by the RMF and the QSM control information parameters by the
QSM specific NSLP processing.

Best regards
nader
