Problems solved by technology

The disadvantage of this method is: the load of the main service node is too high, the resources of the slave service nodes cannot be reasonably utilized, and adding service nodes to the cluster does not improve the performance of the overall service

Embodiment Construction

[0015] The present invention provides a method for realizing an object registration center cluster based on an object type and a hash ring, and the method includes:

[0016] Such as figure 1 As shown, a consistent hash algorithm is selected to construct a first-order hash ring. Use the node name, IP or supported object type as parameters to calculate the hash value of each node in the object registry cluster, and distribute the object registry nodes to the hash ring according to the location of the hash value, as shown in the figure 3 The distribution of object registry cluster nodes.

[0017] When the client initiates an access request, it first performs hash calculation on the requested keyword through the consistent hash algorithm, and maps the result of the hash calculation to figure 1 A point on the circle shown. If the point just hits a certain object registry cluster node, select this node to process the access request; otherwise, search in a clockwise direction unti...

Abstract

The invention discloses an object registration center service cluster implementation method based on an object type and a Hash ring. The method comprises the following steps that a consistent Hash algorithm is selected to establish the Hash ring, the Hash values of all object registration center service nodes are calculated, so that the object registration center service nodes are mapped to the Hash ring, and an object registration center service cluster is formed. An object access request of a client end is calculated through the same consistent Hash algorithm, and the corresponding object registration center service node is selected to process the request according to the position where a calculation result is mapped to the Hash ring.

Description

technical field [0001] The invention relates to an implementation method of an object registration center service cluster based on an object type and a hash ring in a smart grid operation system. Background technique [0002] The consistent hashing algorithm was proposed by MIT in 1997 to solve hotspot problems in the Internet. Consistent hashing proposes that in a dynamically changing cache environment, the hash algorithm should meet four conditions: balance, monotonicity, dispersion, and load. The hash ring is a virtual ring formed by the value space of the consistent hash algorithm. [0003] The object registration center is a unified management facility for global objects in the smart grid operation system. It manages the global naming, global coding and object types of professional application systems in production, monitoring, and office automation, ensuring effective data interaction between professional application systems. . Due to the large amount of total data ...
