访问控制列表在网络访问控制、网络流量识别和网络策略实施等方面起着重要的作用,访问控制列表的设计和部署也对网络性能产生较大的影响。为降低数据包访问控制的延迟、提高网络传输效率,该文对比了在不同的网络层次应用访问控制列表的2种方法。通过数学分析2种方法的数据包传输效率,发现网络负载不同会对网络性能造成不同的影响,运用合理可以优化网络性能。实验和数据结果分析验证了2种方法对网络性能的影响,为网络优化提供了参考。
Access control lists play an important role in network access control, network traffic identification and network policy enforcement. The design and deployment of access control lists also have a significant impact on network performance. In order to reduce the delay of packet access control and improve the efficiency of network transmission, this paper compares two methods of applying access control list at different network levels. Through mathematical analysis of two methods of data packet transmission efficiency, it is found that different network load will have different impact on network performance, and the use of reasonable methods can optimize the network performance. Experiments and data analysis verify the impact of the two methods on network performance and provide a reference for network optimization.
