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.

Abstract: An improved grant/seize processing method with respect to a Moreta-mode when converting an object-oriented CHILL to a CHILL which is capable of defining a syntax having a new characteristic which is capable of granting/seizing by the module unit with respect to a Moreta mode when converting the object-oriented CHILL into the CHILL and granting/seizing by the module unit in the CHILL with respect to the Moreta-mode by using the syntax, for thus achieving excellent effect for providing a function similar to the grant/seize of an actual Moreta-mode.
