Assuming a certain total cost of a given computation network (C), what is the bound on the output rate, as a QoS.

Assuming a desired minimum QoS (output rate) for a given computation network, what is the bound on the number of data streams (maximum possible number of streams to be supported).

Conversely, given a desired minimum QoS, and a given set of registered multimedia data streams, what is the bound on the complexity of the computation network (i.e. the cost C).
