Problems solved by technology

[0004] However, for asymmetric services, the data stored in each service node is different, and the service instance cannot be accurately obtained through the load balancing algorithm. Therefore, a discovery method applied to asymmetric services is urgently needed

Abstract

An embodiment of the present invention provides an asymmetric service discovery method and device, the method comprising: the routing node obtains a group routing table according to the field to which the query content corresponding to the query statement belongs, and the service nodes belonging to the same group are stored in the group routing table The service nodes belonging to the same group provide service instances in the same domain; the routing node obtains the corresponding hash value of the query statement according to the hash routing table corresponding to the group routing table and the hash value corresponding to the query statement. The target service node, the hash routing table stores the hash range of each service node in the packet routing table; the routing node finds the service instance corresponding to the query statement according to the target service node, and Quickly and accurately obtain asymmetric service nodes.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to an asymmetric service discovery method and device. Background technique [0002] In cloud-based microservice applications, the network addresses of service instances are dynamically allocated, and because the system can automatically adjust the size and upgrades and other factors, the number of running instances of the service is also dynamically changed. Therefore, the client needs to use a very fine-grained and accurate service discovery mechanism to obtain service instances. [0003] Among existing service discovery mechanisms, one discovery mechanism is a client discovery mechanism. In the specific implementation process, when using the client discovery method, the client obtains the actual network address (IP address and port number) of the available service by querying the service registration center. The network address can provide multiple service ...
