A proposal of a new packet scheduling algorithm and its evaluation

ITU and other SDOs have launched oneM2M initiative recently and the standardization of M2M is now accelerating. The current access and core networks built for today's network services will be used as a common network infrastructure for M2M network with some modifications. When the current access and core networks are used for both the current network services and M2M services, communications equipments at the network edge need to handle a large number of communication flows which are a mix of large volume data communication such as web access and M2M data communication at the same time. To satisfy the QoS requirements of many applications including M2M applications, communications equipments at the network edge will need to support both minimum guaranteed rate service and low delay forwarding service for small sized packets. In this paper, we propose a packet scheduling algorithm which can provide minimum guaranteed rate service and which can reduce the scheduling delay of small packets. It can be used in access network communications equipment such as edge router and OLT. We also evaluate the proposed algorithm by simulation.
