Problems solved by technology

[0004] However, in the above-mentioned prior art, data nodes randomly receive heartbeat messages from other data nodes, and the time to receive heartbeat messages from the same data node again is uncertain, so it is difficult to determine the heartbeat detection duration for judging whether other data nodes fail
If the time for the data node to receive the heartbeat message from the same data node again is relatively long, then if the heartbeat detection duration is set relatively short, it is easy to cause false detection of faults, but if the heartbeat detection duration is set relatively long, the detection The time to failure is relatively long, it may not be effective, and it has a relatively large impact on business processing

Embodiment Construction

[0081] Embodiments of the present invention provide a distributed heartbeat detection method, device and system for improving the efficiency of detecting node failures.

[0082] In the embodiment of the present invention, a central node is added in the distributed node system, and the central node controls the heartbeat detection relationship between data nodes in the node system. The central node in the present invention only handles the affairs related to the heartbeat view, and does not participate in the sending and processing of the heartbeat message, thereby not restricting the expansion of data nodes in the storage system. In addition to the central node, there are various data nodes arranged in a distributed manner in the node system, and the data of each node transmits heartbeat messages to each other, and each data node detects the node status of other data nodes according to the heartbeat message.

[0083] For ease of understanding, see figure 2 , in the embodimen...

Abstract

An embodiment of the invention discloses a distributed heartbeat detection method used for improving efficiency in internode fault detection. The method includes: a central node generates one corresponding heartbeat view for each data node according to topological structure of a node system, the heartbeat view of any data node is used for marking heartbeat detection relation formed by the data node with other different data nodes, each heartbeat view is transmitted to the corresponding data node, and accordingly the corresponding data node sends out a heartbeat message according to the heartbeat view.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a distributed heartbeat detection method, device and system. Background technique [0002] With the explosive growth of information, higher requirements are placed on the capacity and scalability of storage systems, so a number of emerging concepts and products such as cloud storage and big data have emerged. A cloud storage system usually consists of a large number of storage nodes and can be expanded on a large scale. The reliability and availability of the system are improved through mutual data replication and backup between storage nodes. When performing data replication and backup, the storage nodes need to know the corresponding Therefore, node failure detection technology becomes an important technology for building large-scale storage systems. Distributed technology is the basis for building large-scale cloud storage systems. Currently, node failure detec...
