OpenFlow standards has greatly promoted the development of the next generation internet. However, OpenFlow itself is also facing challenges. The frequent communication between OpenFlow switch and Controller will increase the delay and consume network bandwidth. According to the characteristic of the frequent communication between OpenFlow switch and Controller, the state behavior forwarding algorithm is proposed. This algorithm optimizes the access frequency of forwarding, effectively reduce the communication between OpenFlow switch and Controller, and reduce the delay and bandwidth consumption.%OpenFlow标准的推出极大的促进了下一代互联网的发展。然而OpenFlow技术本身的结构也面临着挑战,由于OpenFlow交换机需要不断与Controller通信会增大延时,消耗网络带宽。本文针对OpenFlow交换机与Controller通信频繁的特点,提出了状态行为转发算法,该算法通过对转发表的访问频率方面进行优化,有效减少了OpenFlow交换机与Controller通信,降低了延时和带宽损耗。
