Abstract: A processing system may identify first virtual circuits and first client systems associated with a first network-to-network interface between a first communication network and a second communication network, the first network-to-network interface having a first bandwidth parameter. The processing system may next select at least a first portion of the first client systems for transfer from the first virtual circuits associated with the first network-to-network interface to second virtual circuits associated with a second network-to-network interface between the first communication network and the second communication network, the second network-to-network interface having a second bandwidth parameter. The processing system may then generate an order to establish the second virtual circuits via the second network-to-network interface and transfer the at least the first portion of the first client systems to the second virtual circuits via the second network-to-network interface.
