Abstract:
PURPOSE: An Internet string code address system structure and a hierarchical label switching method during packet routing by using an Internet string code address system are provided to apply a domain name address system to an address ID of the Internet when using a string code address system in an Internet network, thereby supplying a more convenient address system as resolving an address exhaustion problem. CONSTITUTION: A structural diagram(600) of an Internet string code address system consists of 24 bytes including 5 fields in total. Initial 3 bytes of the address system are used as a TLA SCID(Top Level Aggregation String Code Identifier)(610). The rest bytes are used by setting an address plan for an Internet provider assigned with an address. The rest bytes include a node name(620), an ISP string code identifier(630), a domestic regional string code identifier(640), and a national string code identifier(650).

PURPOSE: A method for extending an IPv4 address system, a method for switching a label using the extended IPv4 address system, and a recording medium storing the same are provided to solve a matter of exhaustion of IPv4 addresses without modification for all the application programs on a node using an existing IPv4 address system. CONSTITUTION: A HIPv4(Hybrid IPv4) address system, 96 bits, consists of a TLA LID(Top Level Aggregator Label Identifier) field(410), a country aggregator label ID field(420), a domestic area aggregator label ID field(430), an ISP aggregator label ID field(440), and an IPv4 address field(450). The TLA LID field(410) is not used in marking a generic address, but used in discriminating between a generic packet, anycast packet, and a multicast packet on the Internet. A character ':' is used to discriminate between the label ID fields and the IPv4 address field. Each label ID field is 16 bits, and marked 2 bits by 2 bits in a dotted hexa method. The IPv4 address field is marked 1 bit by 1 bit in a dotted decimal method.
Abstract:
PURPOSE: A system for managing an event for minimizing a load in a distributed processing system and a method thereof are provided to reduce a network load and execute a transmission rapidly by selecting events only wanted by an event consumer and transmitting the events from an event provider directly. CONSTITUTION: A registration unit(110) registers a name of an event and a pattern conditional expression of the event from event providers. A condition search unit(130) searches event names received from event consumers and a pattern conditional expression of an event. An information transmission unit(150) transmits information with respect to an event provider who satisfies the event conditional expression searched in the condition search unit(130) to the event consumer. A storage(120) stores the event providers, event names received from the event consumers, and the event pattern conditional expression. A complex event creation unit(140) creates a complex event pattern corresponded to information received from the event consumer.
Abstract:
PURPOSE: A method for simulating a parallel program is provided to simulate a parallel program in a simplex system by connecting a process management and control routine which an operation system of each processor supports to each execution block. CONSTITUTION: An execution time support system is connected to each execution block(300). Each execution block recognizes information of a processor(302). Each execution block generates a process on the basis of the information of the processor(304). Each process confirms whether an execution code is terminated(306). In case that the execution code isn't terminated, each process confirms whether the present execution code is a distributed process execution statement(308). In case that the present execution code is the distributed process execution statement, the relevant distributed process execution statement is performed(312). In case that the present execution code is a general execution statement, the general execution statement is performed(310).

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. Also, an IPv4 address processing level can design a network using all conventional IPv4 addresses. Thus, network designing is easy.
Abstract:
PURPOSE: A method for performing an intersection debugging of a chill program using a debugger master is provided to effectively debug a program by enabling two users to simultaneously execute and debug a program using a debugger master in a host system. CONSTITUTION: The first debugger transmits a debug request message including a user identifier of the first debugger and an IP address to the second debugger(101). The second debugger transmits a debug response message including a user identifier of the second debugger and an IP address to the first debugger(102). The first and the second debugger respectively transmit a common debugging connection request message including the user identifiers to a chill debugger master(103,104). The debugger master respectively transmits a response message including user instance values to the first and the second debugger(105,106). The first debugger transmits a channel connection request message including a program name to the debugger master(107). The debugger master transmits the same message, which the first debugger transmits to the second debugger(108). Simultaneously, the connection message including the program name is transmitted to a remote debugger server(109). The remote debugger server transmits a connection response message to the debugger master(110). The debugger master respectively transmits the connection response message to the first and the second debugger(111).
