【 摘 要 】
An implementation technique for traffic splitting using a meter table of a standard OpenFlow in a software-defined network is proposed. The proposed technique uses different differentiated services code point (DSCP) numbers, which are generally used to classify network traffic for quality of service (QoS) levels, in a packet header to decide an output port for a corresponding route. The meter table is generally designed for a QoS purpose. The OpenFlow standard provides two types of meter band, âdropâ and âdscp_remarkâ. The proposed technique adopts the âdscp_remarkâ type for a splitting traffic purpose, instead of the QoS purpose. The DSCP number of the packet is modified when the packet rate exceeds a pre-defined traffic rate. Packets with different DSCP numbers are sent out to the neighbour switches from their corresponding output ports. The original DSCP number is returned to the packets when they are sending out to the neighbour switches, so that the QoS is not affected.
