Abstract:
Provided is a Multi-layer Internet Protocol (MLIP) for peer-to-peer service of a private Internet and a method for transmitting/receiving a MLIP packet through IPv4 backbone network. The Multi-layer Internet Protocol (MLIP) packet comprises a source address field for saving a public Internet address of the source; a destination address field for saving a public Internet address of the destination; and an option field including, an option class field for saving data indicating that the information on a private Internet address is saved in the option field; an option length field for saving data on the length of the private Internet address information; a source sub-address field for saving the private Internet address information of the source; and a destination sub-address field for saving the private Internet address information of the destination. According to the MLIP and the method for transmitting/receiving the MLIP packet, addresses are expanded according to IPv4 within the private Internet without impacting on the internal router in the existing Internet. Therefore, an IPv4 router need not be replaced. All the access networks use the currently-defined private Internet addresses including one A class, 16 B classes and 255 C classes, providing peer-to-peer services between private Internet.
Abstract:
PURPOSE: A telephone number DNS(Domain Name System) on the Internet network and an operating method thereof are provided to mange a telephone number system with the DNS widely used over the Internet, as a unique identifying system in the world. CONSTITUTION: In a telephone number DNS client(200), a telephone number inputting part(201) receives a telephone number inputted from a user. A domain name converting part(202) converts the inputted telephone number to a domain name. An address requesting part(203) requests an IP(Internet Protocol) address corresponding to the converted domain name. And the first storing part(204) stores the converted domain name. In at least one telephone number DNS domain server(210), an address searching part(212) searches an IP address upon the request of the IP address requesting part(203). And an address responding part(214) delivers the searched IP address to the telephone number DNS client(200).
Abstract:
PURPOSE: A method for extending Internet protocol address in an Internet edge router is provided to accept all existing IPv4 services and extend to a new service by using an IPv4 address extension scheme. CONSTITUTION: A message is received from a network interface(100). If a destination address of the message is identical to the its IP(102), it is determined that there are control information(110). If so, Internet control message protocol packet is processed(112). If there are not control information(110), a packet address and connection information are stored(114). If a type of the packet is UDP(User Datagram Protocol(116), UDP packet is processed(118). If a type of the packet is TCP(Transport Control Protocol)(116), TCP packet is processed(120).
