An adaptive bandwidth allocation mechanism for the calendar associated with the Flexible Ethernet (FlexE) standard is proposed. The proposed method bases the FlexE calendar design on the clients' real transmit data rates. In particular, the proposed method treats clients with very low bandwidth utilization as minor clients and allows them to transmit in an opportunistic manner. Experiments on real Ethernet packet traces indicate that by using the proposed calendar scheme to allocate bandwidth to clients, the total required FlexE bandwidth can be reduced by up to 60% while meeting packet drop requirements.
