The GQOS service provider (GQOS SP) is the GQOS component that invokes nearly all resulting QOS facilities. The GQOS SP instigates Traffic Control functionality (if appropriate), and implements, maintains, and handles RSVP signaling for all of GQOS functionality.
The GQOS SP, by virtue of the fact that it implements and maintains RSVP and is the initiator of Traffic Control, is at the heart of GQOS.
