Abstract

The invention discloses a network address layered structure design and maintenance method based on geographical administrative divisions, belonging to computer application technology field. The invention is to solve problem for effectively dividing network address of whole Internet under IPv6 network address condition and designs corresponding network router strategy based thereon. The principle is that network is managed and divided according to geographical administrative divisions layered structure and IP network address of user terminal can be divided into several segments; the routing mode is divided into three mechanisms of uplink, middlelink and downlink according to layering and data packet transmission direction. The layered structure of the invention enable the network data transmit in regularity, reduces unnecessary routing spending and promotes network efficiency, implements network positioning to a certain degree, strengthens network safety, reduces memory size of routing table, saves routing address time, and effectively avoids jam of middle and lower routing system.

Description

technical field

[0001] The invention relates to a method for designing and maintaining a hierarchical network address structure based on geographic administrative divisions, and belongs to the technical field of computer applications. Background technique

[0002] With the development of the Internet address system from the initial IPv4 to the IPv6 that is being perfected and promoted today, the addressing space is expanded from 32 bits to 128 bits, and the problem of insufficient IP address allocation of network equipment has been solved. The IPv6 network address system currently in use internationally has three address structures: unicast, multicast and anycast:

[0003] A unicast address is divided into two parts. The first part contains the address prefix and the second part contains the interface identifier. A unicast address is used to identify a single interface. Packets sent to this address are delivered to the identified interface. A unicast address is distinguish...
