                                                        throws java.lang.Exception

The flow_of_interest low priority supersedes the wish to bound all flows in flows_to_bound, i.e., if flow_of_interest will be removed from flows_to_bound before bounding the arrivals such that the result will always hold (only) for {flows_to_bound} \ {flow_of_interest}.

To bound all flows in flows_to_bound, please call, e.g., computeArrivalBounds( server_graph, flows_to_bound, Flow.NULL_FLOW )

Parameters:

server - The server seeing the arrival bound.

flows_to_bound - The flows to be bounded.

flow_of_interest - The flow of interest to get a lower priority.

Returns:

The arrival bound.

Throws:

java.lang.Exception - Potential exception raised in the called function computeArrivalBounds.
