摘要
现代计算机网络技术发展迅速,SDN具有转发与控制分离、应用灵活多变、适应性强等特点,已逐渐被IT厂商和电信运营商所接纳并采用,但SDN作为一种发展中的技术很多方面还有待完善。本文首先将IP层相关协议的通信过程进行了分析,然后针对SDN的Reactive交换机模式将这些协议的通信效率与以太网进行了对比。实验与分析表明,在地址解析、连通性测试和数据传输等基本网络行为中,SDN的Reactive交换模式效率并不占据优势,需要进一步优化。
Modern computer network technology has developed rapidly.SDN has the characteristics of separation of forwarding and control,flexible application and strong adaptability.It has been gradually accepted and adopted by IT manufacturers and telecom operators.However,SDN as a technology also has its shortcomings.This paper first analyzes the communication process of IP layer related protocols,and then compares the communication efficiency of these protocols with Ethernet for SDN's Reactive switch mode.The experiment and analysis show that the efficiency of SDN's Reactive switching mode is not dominant in the basic network behaviors such as address resolution,connectivity testing and data transmission,and needs further optimization.
