This draft describes a QSpec template for the QoS NSIS Signaling Layer Protocol (QoS NSLP) for signaling QoS reservations in the Internet. A QSpec is transported in QoS-NSLP messages and is opaque to QoS NSLP. It contains the QoS Signaling Model (QSM) Control Information and QoS Description parameters. Control Information is, for example, the scope of a particular QSpec. QoS Description parameters are primary input and output parameters of the Resource Management Function. They include descriptions of the QoS desired and the QoS reserved. QoS Description parameters can also be used for collecting information about resource availability along the path and for signaling a range of acceptable QoS. The QSpec template defines generic parameters that are common to many QSMs. Particularly they are derived from the IntServ and DiffServ QoS Models. They should be used by all QSMs if applicable and must be understood by all QNEs. By identifying the generic parameters we aim to ensure interoperability between different QSMs.
