	Generic (domain independent)			Quality of Service (QoS) Constraint allows to express limits on the values that some QoS characteristic can take. It allows to specify whether this limits are offered (guaranteed by a provider) or requested (needed by a client).UML classes make it possible to represent a QoS contract which links offered and requested QoS levels between two participants, including the degree to which the constraints are to be satisfied (e.g., Guarantee, Best-Effort) and their extent (e.g., end-to-end). Constraints can be composed of other constraints. {SYN: QoS Constraint}
