Historical measures of QoS for data services have involved packet delivery parameters such as cell loss and delay, but these are not directly representative of a user's perception of the delivered video quality.

The realization of QoS often requires mechanisms such as advance or on-demand reservation of resources, varying in type and implementation, and independently controlled and monitored. Foster et al. propose the GARA [10] architecture. The GARA library provides a restricted repres...
