Title:
CONGESTION CONTROL METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/086385
Kind Code:
A1
Abstract:
Disclosed in an embodiment of the present invention is a congestion control method, comprising: a first network nodeconductsa priority-based flow control (PFC) detection for an inlet port, and if a data flow occurring congestion within a set detection period is detected, a flow identification of the data flow is obtained; the first network node generates a PFC frame comprising the flow identification of the data flow, and transmits the PFC frame to a second network node, so as to instruct the second network node to conduct the congestion control for the data flow. The embodiment of the present invention enables the PFC mechanism to conduct the congestion detection for the specific data flow by improving the existing PFC mechanism, transmits the congestion level to an uplink node via the improved PFC frame, and flexibly processes the data flow according to a congestion situation, thus effectively handling with the problems of the change of network data traffic and congestion diffusion, and improving efficiency of the whole network system. Also disclosed in the embodiment of the present invention are a network node, system and computer readable medium.
