近年来，随着互联网流量的增长，网络设备的功耗也随之增加。为了解决这个问题，许多研究人员提出了OpenFlow网络链路速率切换的方案。例如，我们之前提出了一种基于自适应链路速率切换概念的方法，该方法根据链路的使用情况在高速率和低速率之间切换。此外，该方法提供了由多个低速率链路构成的中速率，但比高速率链路消耗更少的功率。结果表明，与简单的自适应链路速率切换相比，功耗可以降低，但仅适用于 MPTCP（多路径 TCP）上的通信。为了给TCP、UDP等其他协议提供方法，本文提出了一种基于流量分割的自适应链路速率切换方法，该方法使用OpenFlow计量表。计量表测量流量速度，并且如果速度超过预定义值（例如链路带宽），则可以更改 IP 标头中的 DSCP（差分服务代码点）字段。分流方法根据流量大小为每个DSCP值分配不同的路由，从而将流量分成多条路由。在划分业务流时，所提出的方法将自适应链路速率从低速率切换到中速率。当业务速度超过中速率时，所提出的方法还将最短链路的速率切换到高速率，并将所有划分的链路聚合到高速率链路上。本文在仿真网络上验证了所提出方法的可行性，并计算了典型流量模式下的功耗降低量，表明与简单的自适应链路速率相比，功耗可以降低。
In recent years, power consumption from network devices has increased as Internet traffic has grown. In order to address this problem, many researchers have proposed schemes that switch the link rate for OpenFlow networks. For example, we previously proposed a method based on the adaptive link rate switching concept which switches between high and low rates based on the usage of the link. Furthermore, the method provided a middle rate, which is constructed from multiple low rate links but consumes less power than that of a high rate link. It showed that power consumption can be reduced from that of simple adaptive link rate switching, but provided only for communications over MPTCP (Multipath TCP). To provide the method for other protocols such as TCP and UDP, this paper proposes a new adaptive link rate switching method based on traffic splitting, which uses OpenFlow meter tables. The meter tables measure traffic speeds and can change the DSCP (Differentiated Services Code Point) field in IP headers if the speeds exceed a pre-defined value such as a link bandwidth. The traffic splitting method assigns a different route for each DSCP value depending on the traffic volume, so dividing a traffic flow into multiple routes. On dividing a traffic flow, the proposed method switches the adaptive link rate from the low rate to the middle rate. When the traffic speed exceeds the middle rate, the proposed method also switches the rate of the shortest link to the high rate and aggregates all divided links onto the high rate link. The paper verifies the feasibility of the proposed method on an emulated network and also calculates the power consumption reduction over a typical traffic pattern to show that power consumption may be reduced from that of a simple adaptive link rate.
