Network address design method and data resource scheduling method based on geographic SOT (GeoSOT) subdivision codes

Abstract

The invention discloses a network address design method and a data resource scheduling method based on geographic SOT (GeoSOT) subdivision codes, and belongs to the field of geographic space information organizations, geographic information systems and computer networks. The network address design method comprises the steps of obtaining a binary system one-dimensional GeoSOT code containing the smallest GeoSOT subdivision surface patch of a geographic range of user host machine management data resources, obtaining a 64-bit host machine code, enabling a hierarchy where the subdivision surface patch is located to be converted to be a 5-bit binary system code, obtaining a subdivision hierarchy code, combining the subdivision hierarchy code and the host machine code to be a geographic internet protocol (GeoIP) code which serves as rear 69 bits in an internet protocol version 6 (IPv6) address, obtaining a GeoIP address, conducting subnet division on the GeoIP address, and setting a subnet mask. The data resource scheduling method comprises the steps of designing a GeoIP address of a user host machine, confirming a GeoIP address of a receiving host machine by a sending host machine according to the geographic space range which the obtained data relate to, packaging the data and the GeoIP address of the receiving host machine to be a GeoIP data packet, and transmitting the GeoIP data packet to the receiving host machine. The network address design method and the data resource scheduling method based on GeoSOT subdivision codes are applicable to space-time organizations of network space data resources.

Description

technical field [0001] The invention relates to a network address design method and a data resource scheduling method based on GeoSOT subdivision coding, and belongs to the fields of geographic space information organization, geographic information system and computer network. Background technique [0002] Usually, the form of original remote sensing image recording is: first record the observation time, and then sequentially record the observation value of each reflection point within the field of view. This "spatial-temporal recording" method profoundly affects the operation of all aspects of the spatial information management system. For example: We often divide image records into three storage states of "online, near-line, and offline" in chronological order. In the space-time record system, data records received at different times are stored in different files, and data resources When scheduling, it is usually necessary to schedule data according to the area range of t...
