Decentralized service cluster system and fault detection method for location service

Abstract

The invention discloses a non-centralized service cluster system for position service and a fault detection method, and the system employs the regional division to enable each region to be distributedon different service nodes, and guarantees that the complexity of the read-write time is not increased due to the increase of a user. When the designed performance bottleneck is reached, the area isdivided into a plurality of areas to be expanded transversely, so that the high-concurrency read-write requirement is met. By carrying out the master-slave design on the area, and when the service node where the area is located breaks down, providing services by the backup node, the high availability is realized. The network topology is obtained among the service nodes through regular message synchronization and fault detection, the requests are routed to appropriate service nodes, and the final consistency is kept. The suspected node is marked by directly and indirectly sending the detectionmessage, and the suspected node is waited to be reversely connected, so that false alarm caused by the fact that the message cannot be replied in time is avoided. And meanwhile, the time for sending the detection message and the suspected node to be suspected is dynamically adjusted to accelerate the convergence of the network topology.

Description

technical field [0001] The invention belongs to the technical field of location services, and more specifically relates to a decentralized service cluster system and a fault detection method for location services. Background technique [0002] The location service needs to query the nearby service users according to the latitude and longitude of a point. Many business services depend on location services. For the field of transportation and travel, it is necessary to find nearby drivers. The driver's position changes relatively greatly, and the accuracy requirements for the driver's position are relatively high, otherwise, it will lead to the driver's refusal to load and the customer's complaint. For the urban intelligent system, it is necessary to judge the congestion condition of the road, which also has very high requirements for the accuracy of the actual geographic location of the location service user. Therefore, the high availability of location services and the re...
