  • Method of extending IPv4 address architecture, label switching method using the extended IPv4 address architecture and recording medium for the extended IPv4 address architecture
    Publication number: 20030212771
    Abstract: A method of extending an Internet Protocol version 4 (IPv4) address architecture, a method of switching labels using the extended IPv4 address architecture, and a recording medium for recording the extended IPv4 address architecture, are provided. In the IPv4 address architecture extending method, an Internet service provider (ISP) level aggregation label identifier for identifying an ISP is attached to an IPv4 address. A regional-level aggregation label identifier for identifying a region is attached to the IPv4 address to which the ISP-level aggregation label identifier has been attached. A national-level aggregation label identifier for identifying a nation is attached to the IPv4 address to which the ISP-level and regional-level aggregation label identifiers have been attached. According to such a method described above, running out of IPv4 addresses can be solved without changing all application programs on the nodes using conventional IPv4 addresses and installing an extra address transformer.
