Problems solved by technology
When a deadlock fault occurs in RDMA, the network will stop flowing and services will be unavailable, which will lead to problems such as the inability to observe the delayed data transmitted by the network, and abnormal CPU utilization.
In related technologies, network anomaly monitoring cannot distinguish whether the network anomaly is an RDMA deadlock, and operation and maintenance personnel familiar with RDMA technology are often required to identify and judge deadlock faults
This will undoubtedly increase the cost of network anomaly monitoring, and requires high requirements for operation and maintenance personnel

The invention provides a method and a device for positioning a deadlock fault in a topological structure. The topological structure is composed of m pieces of network equipment, and the positioning method comprises the following steps: in response to network exception information sent by n pieces of network equipment in the m pieces of network equipment, determining that the n pieces of network equipment are exceptional network equipment; obtaining respective operation information of the n abnormal network devices; and determining the network equipment with the deadlock fault in the n pieces of abnormal network equipment according to the operation information, wherein m and n are integers greater than or equal to 3, and m is greater than or equal to n.
Description
technical field [0001] The present disclosure relates to the field of network technologies, and more particularly, to a method and device for locating deadlock faults in a topology structure. Background technique [0002] With the continuous advancement of the IT architecture transformation of financial institutions, and the continuous promotion and application of big data, AI, and distributed technology architectures, the internal network of financial institutions' data centers has presented higher challenges for high-bandwidth and delayed transmission. The high-performance RDMA (Remote Direct Memory Access, Remote Direct Data Access) protocol with high bandwidth, low latency, and low CPU resource utilization is increasingly chosen by financial institutions. [0003] During the process of realizing the concept of the present disclosure, the inventors found that there are at least the following problems in the related art: the RDMA network will bring a new network risk-deadl...
