一种拥塞控制的方法、设备和系统技术方案

本发明专利技术实施例公开了一种拥塞控制的方法，包括：第一网络节点对入端口进行基于优先级的流控(Priority‑based Flow Control，PFC)检测，如在设定的检测周期内检测到某一数据流发生拥塞，获得该数据流的流标识；第一网络节点生成包括该数据流的流标识的PFC帧，并发送该PFC帧到第二网络节点，指示第二网络节点对该数据流进行拥塞控制。本发明专利技术实施例通过在对现有的PFC机制进行改进，使得PFC机制能对某条具体的数据流进行拥塞检测，并将拥塞程度通过改进后的PFC桢发送给上行节点，可根据拥塞情况对数据流进行灵活处理，可以有效应对网络数据流量的变化和拥塞扩散的问题，提高了整个网络系统的效率。本发明专利技术实施例还公开了一种网络节点、系统和计算机可读介质。

Method, device and system for congestion control

The embodiment of the invention discloses a method for congestion control: the first network node to the port priority based flow control (Priority based Flow Control, PFC) detection, such as in the detection period set detected within a data flow congestion occurs, obtain flow identification of the data stream; first the network node generated including flow identification PFC frame of the data stream, and transmits the PFC frame to the second network nodes, indicating that the second network node congestion control on the data stream. The embodiment of the invention based on the existing PFC mechanism is improved, the PFC mechanism can detect congestion on a particular data stream, and the degree of congestion by sending the improved PFC frame to uplink node according to the congestion of data flow is flexible and can effectively deal with changes in the network traffic and congestion diffusion problems, improve the efficiency of the whole network system. The embodiment of the invention also discloses a network node, a system and a computer readable medium.
