Allocating network bandwidth

As an example, a system and method is provided for allocating network bandwidth. The method includes identifying congested and uncongested links using a tenant demand for each link and a tenant bandwidth cap. A portion of the tenant bandwidth cap may be allocated to each uncongested link based on the tenant demand on the uncongested link and the tenant bandwidth cap. Additionally, the remainder of the tenant bandwidth cap may be allocated to the tenant's congested links based on a link capacity.
