Abstract: A system and method may include receiving a new flow request, the new flow request for requesting provisioning of a flow between a computer and the server, identifying a path of one or more network elements between the computer and the server, and determining whether provisioning the flow between the computer and the server violates a constraint. The system and method may further include updating an oversubscription factor and available bandwidth for an interface of each of the one or more network elements in the event the constraint is not violated, and determining whether a second path exists between the computer and the server in the event the constraint is violated.
