Embodiment Construction

[0028] In order to solve the problem of congestion spread and packet loss caused by triggering PFC first and then QCN protocol failure in the prior art through threshold configuration, the present invention provides an Ethernet congestion control method and device, which can effectively solve the two problems in the network. If two protocols are used at the same time, the protocol will fail, which will cause packet loss. The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Abstract

The invention discloses method and device for controlling congestion of an Ethernet. The method comprises the following steps of: closing an ingress port of core network equipment with the function of congestion detection to trigger a flow control PFC (Power Factor Correction) mechanism based on priority through a threshold; detecting whether a message forwarded by the ingress port is a CNM (Congestion Notification Message) or not; generating a PFC message according to the CNM if the message forwarded by the ingress port is the CNM; and forwarding the CNM through the ingress port and notifying the opposite-end equipment of suspending the data transfer of a corresponding queue according to the PFC message. With the technical scheme of the invention, the congestion problem can be quickly and effectively solved fundamentally.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an Ethernet congestion control method and device. Background technique [0002] In related technologies, a data center is a center for providing enterprise application business services, and a center for data calculation, exchange, and storage. The data center combines advanced network technology and storage technology, carries more than 80% of the service requests and data storage capacity in the network, and provides services and operation platforms for the healthy operation of customers' business systems. figure 1 is a schematic diagram of the data center network architecture in the prior art, such as figure 1 As shown, in an enterprise data center, there are three distinct types of networks deployed: an Ethernet to support IP traffic, one or two storage area networks to support Fiber Channel storage traffic, and an InfiniBand to support high-performance cluster computing ...
