摘　　要：网络交换机是现代通信网络的核心设备之一,负责数据包的接收、处理和转发,以确保数据能够有效地在网络中传输。为了提高网络的效率和减少数据传输过程中的延迟与丢包,引入了优先级流控(Priority Flow Control,PFC)和显式拥塞通知(Explicit Congestion Notification,ECN)两种技术。本文详细探讨了PFC和ECN技术在网络交换机中的实现方法,包括这两种技术的配置、单独和集成使用时对网络流量控制和拥塞管理的影响,通过系统测试验证其有效性。通过分析PFC技术对流量控制的影响和ECN技术对拥塞管理的影响,展示了这两项技术如何协同工作,提高网络性能和稳定性。Network switches are one of the core devices of modern communication networks,responsible for receiving,processing,and forwarding data packets to ensure effective transmission of data in the network.In order to improve network efficiency and reduce latency and packet loss during data transmission,two technologies have been introduced:Priority Flow Control(PFC) and Explicit Congestion Notification(ECN).This article provides a detailed exploration of the implementation methods of PFC and ECN technologies in network switches,including their configuration,impact on network traffic control and congestion management when used alone or in combination.The effectiveness of these two technologies is verified through system testing.By analyzing the impact of PFC technology on traffic control and ECN technology on congestion management,we demonstrate how these two technologies work together to improve network performance and stability.
