Abstract

A service registration method and usage method, and a related apparatus are used to reduce risks generated when a service of an AP-type service providing node cannot be registered and a CP-type service providing node provides a service since distributed characteristics of a service providing node are not distinguished in a network partition scenario. The method is: obtaining, by a registration service node, network partition information, and receiving a registration request of a service providing node, where the registration request carries a distributed characteristic of the service providing node, and the distributed characteristic meets both consistency and partition tolerance, or meets both availability and partition tolerance; and determining, by the registration service node according to the network partition information and the distributed characteristic of the service providing node, whether registration of a service provided by the service providing node is allowed.

First claim

The invention claimed is:

1. A service registration method, comprising:
obtaining, by a registration service node, network partition information, and receiving a registration request of a service providing node, wherein the registration request carries a distributed characteristic of the service providing node, and the distributed characteristic meets both consistency and partition tolerance, or meets both availability and the partition tolerance; and
determining, by the registration service node according to the network partition information and the distributed characteristic of the service providing node, whether registration of a service provided by the service providing node is allowed;
wherein the consistency indicates that all nodes have same data at same time, the availability indicates that a response to each request is ensured regardless of success or failure, the partition tolerance indicates that separated systems function properly when there is a network partition.

2. The method according to claim 1 , wherein the determining, by the registration service node according to the network partition information and the distributed characteristic of the service providing node, whether registration of a service provided by the service providing node is allowed comprises:
when the registration service node determines, according to the network partition information, that a registration service node cluster to which the registration service node belongs has the network partition, determining that the registration of the service provided by the service providing node is prohibited if determining that the distributed characteristic of the service providing node meets both consistency and partition tolerance; and determining that the registration of the service provided by the service providing node is allowed if determining that the distributed characteristic of the service providing node meets both availability and partition tolerance.

3. The method according to claim 1 , wherein the determining, by the registration service node according to the network partition information and the distributed characteristic of the service providing node, whether registration of a service provided by the service providing node is allowed comprises:
according to the network partition information and the distributed characteristic of the service providing node, determining, by the registration service node, that the registration of the service provided by the service providing node is prohibited if determining that the distributed characteristic of the service providing node meets both consistency and partition tolerance and a service providing node cluster to which the service providing node belongs has the network partition; and determining that the registration of the service provided by the service providing node is allowed if determining that the distributed characteristic of the service providing node meets both availability and partition tolerance.

4. The method according to claim 3 , wherein the obtaining, by a registration service node, network partition information comprises:
receiving, by the registration service node, the network partition information reported by the service providing node, wherein the network partition information is reported by the service providing node when the service providing node determines that communication between service providing nodes in the service providing node cluster to which the service providing node belongs is interrupted.

5. A registration service node device, comprising:
a memory, a program stored in the memory, and a processor;
wherein the processor is configured to read the program and execute the program to perform:
obtaining network partition information, and receiving a registration request of a service providing node, wherein the registration request carries a distributed characteristic of the service providing node, and the distributed characteristic meets both consistency and partition tolerance, or meets both availability and the partition tolerance; and
determining, according to the network partition information and the distributed characteristic of the service providing node, whether registration of a service provided by the service providing node is allowed;
wherein the consistency indicates that all nodes have same data at same time, the availability indicates that a response to each request is ensured regardless of success or failure, the partition tolerance indicates that separated systems function properly when there is a network partition.

6. The device according to claim 5 , wherein the processor is configured to further perform:
when determining, according to the network partition information, that a registration service node cluster to which the registration service node belongs has the network partition, determining that the registration of the service provided by the service providing node is prohibited if determining that the distributed characteristic of the service providing node meets both consistency and partition tolerance; and
determining that the registration of the service provided by the service providing node is allowed if determining that the distributed characteristic of the service providing node meets both availability and partition tolerance.

7. The device according to claim 5 , wherein the processor is configured to further perform:
according to the network partition information and the distributed characteristic of the service providing node, determining that the registration of the service provided by the service providing node is prohibited if determining that the distributed characteristic of the service providing node meets both consistency and partition tolerance and a service providing node cluster to which the service providing node belongs has the network partition; and
determining that the registration of the service provided by the service providing node is allowed if determining that the distributed characteristic of the service providing node meets both availability and partition tolerance.

8. The device according to claim 7 , wherein the processor is configured to further perform:
receiving the network partition information reported by the service providing node, where the network partition information is reported by the service providing node when the service providing node determines that communication between service providing nodes in the service providing node cluster to which the service providing node belongs is interrupted.

9. A registration service node device, comprising:
a memory, a program stored in the memory, and a processor;
wherein the processor is configured to read the program and execute the program to perform:
obtaining network partition information, and receiving a query request of a service using node, wherein the query request carries an identifier of a requested service;
determining a service providing node that provides a service indicated by the identifier of the service and a distributed characteristic of the service providing node, wherein the distributed characteristic meets both consistency and partition tolerance, or meets both availability and the partition tolerance; and
determining, according to the network partition information and the distributed characteristic of the service providing node, whether use of the service provided by the service providing node is allowed;
wherein the consistency indicates that all nodes have same data at same time, the availability indicates that a response to each request is ensured regardless of success or failure, the partition tolerance indicates that separated systems function properly when there is a network partition.
