1. A method, comprising: determining whether configured logical bandwidth allotments for one or more logical channels are supported by maximum available physical bandwidths of one or more underlying physical channels assigned to those logical channels by: A) establishing a bandwidth-constraint directed acyclic graph (BCD) based on relationships between vertexes of the BCD that represent one of either logical channels or unions of logical channels or both, as well as one or more underlying physical channels of the logical channels of each vertex and their maximum available bandwidth constraints; and B) traversing the vertexes of the BCD to determine whether the constraints of the vertexes are met.
