Embodiment Construction

[0039] The embodiment of the present application provides a fault detection method of a distributed communication network and a distributed system, by deploying agent processes on each node in the distributed system, and by judging whether the physical link between the agent processes fails, it can increase One-dimensional fault detection helps reduce the overhead caused by fault detection among massive business processes. Wherein, the method and the device are based on the same inventive concept, and since the principles of the method and the device to solve problems are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated. In the description of the embodiments of the present application, "and / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B, which may mean: A exists alone, A and B exist simultaneously, a...

Abstract

The application discloses a fault detection method and device for a distributed communication network, which are used to reduce the overhead of DCN network service process fault detection. The method includes: the first node sends a first detection message to the second agent process through the first agent process, and the first detection message is used to judge the first agent process in the first node and the second agent process in the second node Whether the physical link between the processes is faulty; when the first node determines that the physical link is faulty according to the first detection message, it notifies one or more first service processes of the physical link fault information through the first agent process; When a node determines that the activation condition is satisfied, the first service process is enabled to send a second detection message to the second service process, and the second detection message is used to determine whether the logical link between the first service process and the second service process is Fault, the enabling condition includes that the first service process receives information that the physical link is faulty.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a fault detection method and device for a distributed communication network. Background technique [0002] A distributed communication network (distributed communication network, DCN) includes a large number of nodes. Each node deploys a large number of business processes on its own operating system, so there will be a large number of business processes in the DCN. Different service processes have demands for data communication, and different service processes establish a communication link through an internet protocol (internet protocol, IP) stack to realize data communication. [0003] If the communication link fails or is abnormal, it will affect the data communication between business processes. In order to improve the reliability of data communication, it is necessary to identify whether the link is faulty or abnormal through a fau...
