Label switching method based on area coding

Abstract

The invention refers to a mark interchanging method based on area coding. The method divides the internet into different regions according to the administrative management region, allocates a fixed-length code as the mark of the region to each region, and uses the mark as one part of the net address. The group carry of source transmission, marks interchanging net and user the mark as route interchanging mark. The code of the region is divided into skeletal code and access code, the skeletal code is used to mark skeletal code of oversea code and national / region code; the access code is used tosign correspondent user access net region; the IP group needed to be transmitted to the region beyond the region.

Description

Technical field:

[0001] The invention relates to the technical field of communication, in particular to a label exchange method based on area coding, which is applicable to data communication and exchange of packet Internet. Background technique:

[0002] With the rapid development of Internet technology, people's demand for the Internet is increasing, so there is an urgent need for an Internet forwarding mechanism with high throughput and easy operation. However, most of the current Internet forwarding methods use routers to perform complex processing on Internet Protocol (IP) packet headers, and to perform cumbersome routing lookups in the huge IP routing table, which seriously limits the processing capacity and throughput of routers , affecting the quality of service (QOS), and the IP addresses of the Internet are also facing exhaustion, which have become bottlenecks restricting the development of the Internet. To this end, the International Organization for Standardizat...
