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 device for distributing loads based on an SIP(Session Initiation Protocol) and a method therefor are provided to be installed on a front end of many proxy servers for processing SIP calls, and to consider load degrees for registering a terminal and processing a call for a call routing service, thereby dynamically distributing loads. CONSTITUTION: A system controller(200) controls overall operations of a device. A server list table(240) manages a list of a proxy server in accordance with a destination address of a user. A management factor list table(250) manages the user in accordance with the destination address of a registration message. An input unit(220) inputs a message transmitted from a terminal. A processor(230) decodes the message of the input unit(220), and distributes the registration message to a specific proxy server according to load degrees of each proxy server if the decoded message is the registration message. If the decoded message is a call processing request message or a call complete message, the processor(230) manages overall loads of each proxy server by increasing/decreasing loads in the corresponding proxy servers. An output unit(260) outputs processed results to the proxy servers. A timer task unit(210) periodically checks the server list table(240) and the management factor list table(250), and deletes an expiring list.

Abstract: PURPOSE: An ATM firewall switch device with a call admission control structure and a parallel cell screen structure and a method therefor are provided to minimize the deterioration of an ATM switch and delay of a cell processing time when adopting a virtual connection or packet level security policy. CONSTITUTION: A signal cell filter(200) extracts a signal cell from cells introduced into a screened input unit(102). A management cell filter(201) extracts a management cell from cells which have passed the signal cell filter(200). A parallel cell screen unit(202) reduces a cell processing time delay according to a screen policy application. A header converter(205) adds switch information to a user cell which has passed the parallel cell screen unit(202), and outputs it to a cell switching unit(104). A VP(Virtual Path)/VC(Virtual Connection) table(206) stores allocated VPI(Virtual Path Indicator)/VCI(Virtual Connection Indicator) information and policy information on a virtual line. A security policy cash(207) is referred to determine a security policy. A cell duplicator(203) duplicates introduced user cell as many as the user cell filters(204) and transfers it to a cell filter(204). The user cell filter(204) filters only the cells allocated to itself by referring a VPI(Virtual Path Indicator).

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).
