RoCE network flow control method and device, equipment and storage medium

Abstract

The invention provides a RoCE network flow control method, device and equipment and a storage medium, which can be applied to the financial field or other fields. The method comprises the following steps: obtaining inter-network communication description information and network card residual sending capability information of each source end in a source end set; separating a source terminal set with the same destination end from the source terminal set according to the destination end in the inter-network communication description information; for each source terminal set, determining the flow distribution proportion of each source end in the source terminal set according to the network card residual sending capability information of each source end in the source terminal set; obtaining network card residual receiving capability information of each destination end; and for each source terminal set, determining a single transmission flow upper limit of each source end in the source terminal set according to the corresponding flow distribution proportion and the network card residual receiving capability information of the corresponding destination end, and sending the single transmission flow upper limit to the corresponding source end, so that each source end sends the data stream based on the single transmission flow upper limit. According to the specification, the congestion rate of the RoCE network can be reduced, and the operation stability of the RoCE network is considered.

Description

technical field [0001] This specification relates to the technical field of flow control, and in particular, relates to a RoCE network flow control method, device, device, and storage medium. Background technique [0002] RoCE (RDMA over Converged Ethernet, RDMA technology and Ethernet fusion technology) is a connectionless transport layer protocol based on UDP (User Datagram Protocol, User Datagram Protocol). The reliability of RoCE networks is generally poor, and RoCE networks are extremely sensitive to packet loss. A packet loss of one in 100,000 will cause a sharp drop in transmission performance. Therefore, the deployment of RoCE networks is inseparable from effective flow control mechanisms to ensure high speed reliable transmission. At present, PFC (Priority-based Flow Control, priority-based flow control) technology is generally used in RoCE networks to ensure lossless forwarding, but the PFC mechanism operates at the port level. Injure other service flows, even ca...

Problems solved by technology

The reliability of RoCE networks is generally poor, and RoCE networks are extremely sensitive to packet loss. A packet loss of one in 100,000 will cause a sharp drop in transmission performance. Therefore, the deployment of RoCE networks is inseparable from effective flow control mechanisms to ensure high speed reliable transmission

At present, PFC (Priority-based Flow Control, priority-based flow control) technology is generally used in RoCE networks to ensure lossless forwarding, but the PFC mechanism operates at the port level. Victimize other business flows, even cause PFC storms and deadlocks, and even spread and affect the global network
