Detailed Description
The technical scheme of the invention is specifically described below with reference to the accompanying drawings.
The invention provides a network architecture of a geospatial grid domain name, which is used for providing a support architecture for a geospatial grid domain name registration and resolution service, orienting to ubiquitous location information, determining a server logic relationship of the geospatial grid domain name registration and resolution by organizing domain names and regional domain names, and providing domain name naming authorization, information interaction and registration resolution addressing support; including the geospatial grid domain name distribution service, the geospatial grid domain name global registration resolution service G2RS-GGRN, and the geospatial grid domain name local registration resolution service L2RS-GGRN.

The following is a specific implementation procedure of the present invention.
1. Geospatial grid domain name network architecture
The geospatial grid domain name network architecture (Network Architecture ofGeospatial Grid Region Name, for short, NA-GGRN) is a support architecture for a geospatial grid domain name registration and resolution service, is oriented to ubiquitous location information, determines a server logical relationship of geospatial grid domain name registration and resolution by organizing domain names and regional domain names, and provides domain name naming authorization, information interaction and registration resolution addressing support. The geospatial grid domain name network architecture adopts a spatially extensible and physically distributed system structure, and associates the geospatial grid domain name registration and resolution service components by an open protocol specification, namely the geospatial grid domain name protocol. The geospatial grid domain name network architecture is a data model and topology pointer system for registration and analysis of ubiquitous location information, and the architecture diagram is shown in figure 1.
The geospatial grid domain name network architecture includes a geospatial grid domain name distribution service, a geospatial grid domain name global registration resolution service (Global Registration and Resolution Service of Geospatial Grid Region Name, abbreviated as G2 RS-GGRN), and a geospatial grid domain name local registration resolution service (Local Registration and Resolution Service ofGeospatial GridRegionName, abbreviated as L2 RS-GGRN).
The geospatial grid domain name distribution service specifically includes open protocol specifications, hierarchical namespaces, and distribution of protocols and names, among others. The open protocol specification enables a distributed computing system to store and apply a geospatial grid domain name network architecture for resolving, addressing and locating ubiquitous location information. The open protocol specification comprises four parts of a splitting layer, a management layer, a correlation layer and an application layer, and specifically comprises a grid splitting sub-protocol, a grid coding sub-protocol, a global space grid domain name organization sub-protocol, a global space grid domain name mapping sub-protocol, a global space grid domain name naming authority sub-protocol, a global space grid domain name based transcoding sub-protocol, a global space grid domain name interoperation sub-protocol, a global space grid domain name registration sub-protocol, a global space grid domain name resolution sub-protocol and the like. The geospatial grid domain name namespaces have a hierarchical relationship, the hierarchical namespaces including an organization domain name namespace, a regional domain name namespace, and a proprietary domain name namespace, the hierarchical namespaces providing efficient data organization management. The distribution of protocols and naming is to grant specific open protocol specifications and hierarchical namespace rights for different geospatial grid domain name registration and resolution phases. The geospatial grid domain name distribution service may be applied to a geospatial grid domain name global registration resolution service and a geospatial grid domain name local registration resolution service.
The global registration resolution service of the geospatial grid domain name is responsible for locating and domain name authorization management of all universal position information in the geospatial. The local registration resolution service for the geospatial grid domain name ensures that each L2RS-GGRN can access the G2RS-GGRN, so that any local geospatial grid domain name registration resolution request can access the global registration resolution service, and the local registration resolution service can be accurately positioned on a server providing the geospatial grid domain name registration resolution service. In addition, because the namespaces of the geospatial grid domain names have hierarchical relationships, the local registration and analysis service of the geospatial grid domain names responsible for domain name naming authority has multi-layer upper and lower relationships. Each geospatial mesh domain name local registration resolution service is made up of a plurality of registration resolution service nodes L2RS-ServSite, which can be considered as mirror images because of their identical functionality. The service node configuration of the geospatial mesh domain name local registration resolution service L2RS-GGRN is described below.
Wherein n is the number of local registration resolution services for the geospatial grid domain name, and m i is the number of registration resolution service nodes corresponding to the i-th local registration resolution service for the geospatial grid domain name.
2. Geospatial grid domain name server layer structure
The geospatial grid domain name server is used as a distributed database which can map the geospatial grid domain name and grid address with each other and register and analyze, and can enable people to conveniently access ubiquitous location information without memorizing the grid coding address facing machine identification. The geospatial grid domain name server cluster comprises a root domain name server, an organization domain name server, a regional domain name server, a coding server, a data server and the like. The organization domain name server, the regional domain name server, the encoding server, the data server, etc. all store mapping records of the geospatial mesh root domain name server. The organizing domain name server and the regional domain name server do not need to store the information of all subordinate organizing domain names or regional domain names, only need to record the geospatial grid domain names of the managing range, and save the storage space of the server while guaranteeing the integrity of the geospatial grid domain name system. As shown in fig. 2, the correspondence between the domain name space layer and the server layer from the organization sub domain name server to the data server is shown.
2.1 Root domain name server
The geospatial mesh root domain name server is a core server storing geographic metadata organizing the domain name servers, i.e., the domain name identifiers and organization codes of all organizing domain name servers, and all domain names and organization codes inside the organizing domain name servers. When the organization domain name server cannot normally analyze the domain name of the geospatial grid, a request can be sent to the root domain name server of the geospatial grid to assist in analyzing the domain name.
2.2 Organization Domain name Server
The organization domain name server is mainly responsible for managing all organization domain names registered on the organization domain name server, and responds to requests sent by the geospatial grid domain name system according to the domain name mapping relation. The earth space grid root domain name server and the organization domain name server solve the uniqueness of domain names outside the industry.
The organizing domain name server comprises an organizing root domain name server and an organizing sub domain name server. The organization root domain name server stores and backs up index metadata of the organization sub domain name servers. The organizing sub-domain name server uses internal domain names to save storage space corresponding to an organizing domain name space, such as a hosting root node of a hosting industry.
2.3 Regional Domain name Server
The regional domain name server is responsible for resolving the domain name containing the space position information sent by the geospatial grid domain name system and returning the expression form of the grid code set corresponding to the regional domain name space.
The regional domain name servers include a regional root domain name server and a regional subdomain name server. The regional root domain name server stores and backs up index metadata of the regional sub domain name servers, corresponding to level 1 of the regional domain name space, such as a posting Chinese node of a posting industry. The regional subdomain name servers correspond to the 2 nd to 5 th levels of the regional domain name space, such as Jiangsu nodes of the consignment industry.
2.4 Encoding Server
The coding server generates an organization domain name code, namely an organization code, a regional domain name code, namely a grid code set and a proprietary domain name code, namely a proprietary code, through ubiquitous location information provided by a user application.
2.5 Data Server
The data server corresponds to the 5 th level of the regional domain name space, is managed by organization units in various places, such as street level post offices of the posting industry, stores a large index table of the domain name of the geospatial grid of the street area, and associates the universal position information entities through the large index table.
The invention relates to a network architecture and a server layer structure of a geospatial grid domain name, which comprises the following specific implementation modes:
(1) Building a domain name network architecture of the geospatial grid; (2) geospatial mesh root domain name server deployment; (3) geospatial mesh organizing domain name server deployment; (4) deployment of a domain name server in the geospatial grid area; (5) geospatial trellis encoding server deployment; (6) geospatial grid data server deployment.
The above is a preferred embodiment of the present invention, and all changes made according to the technical solution of the present invention belong to the protection scope of the present invention when the generated functional effects do not exceed the scope of the technical solution of the present invention.
