QNI populates Initiator QSPEC to achieve QoS desired
Case 1: QNI determines as follows:
QNI populates , , & possibly
initializes to
QNEs check if resources can be reserved
if not, QNE reduces parameter values in & reserves these values
minimum parameter values given in
zero if not included
note: RSVP works similarly
ADSPEC in PATH message collects resource availability
RSPEC in RESERVE message based on ADSPEC
QNI populates Initiator QSPEC if satisfactory
Case 2: QNI does not do procedure to determine
QNI populates Initiator QSPEC to achieve
cannot be guaranteed
