Abstract: PURPOSE: A method for scheduling a cell securing a priority of a switch having an input queue is provided to secure both priorities and fairness with a cell scheduler for processing the priorities in a switch having an input queue, thereby expanding applied ranges by efficiently retrieving the priorities. CONSTITUTION: A switch starts from a time slot '0'(400), and creates a cell input table(405). The switch determines 'a' and 'b' values after creating the cell input table(410). The switch selects one 'x' value(415). A generalized diagonal line is produced(420). When the diagonal line is produced, the switch retrieves priorities at the cell input table(425), makes a transmission matrix from a cell having the highest priority, and updates the transmission matrix(430). Until a selected 'x' frequency becomes 'N'(435), the switch changes the 'x' value(440). If only cells having general priorities remain, the switch re-applies an SFCS(Self-Firing Cell Scheduler) algorithm(445), and updates the transmission matrix(450). The switch transmits the cell of the transmission matrix(455).

Abstract: PURPOSE: A method for managing the addresses of a buffer operated by a linked list in an ATM exchange is provided to restore a temporarily generated linked list error and to offer services without executing resetting and restarting additionally by detecting and deleting a duplicated address and finding and recovering a lost address, in the process of requesting address storage to an address pool or storing addresses in the address pool. CONSTITUTION: If an address pool receives an address storage request from a buffer management part(S210), the address pool checks whether the test state is under the test(S220). In case that the present state is under the test, the address pool confirms whether the requested address is a test address(S230). If the requested address is a test address, the address pool discards the requested address after reporting that the requested address is a duplicated address(S240). However, in case that the requested address is not a test address, the address pool adds '1' to the number of stored addresses and stores the requested address in the address pool(S250). Meanwhile, if the test state is not under the test, the address pool sets the start time to '0'(S260). Then the address pool stores the requested address and adds '1' to the number of stored addresses(S270).

CONSTITUTION: A physical layer processing unit(110) extracts an ATM(Asynchronous Transfer Mode) cell from an input signal to transmit the extracted ATM cell to an ATM layer, and converts an ATM cell received from the ATM layer to output the converted ATM cell. A transmitting unit(100) adds an FM cell including performance information about a block just transmitted until a performance block of the ATM cell received from the physical layer processing unit(110) is completed, and transmits the ATM cell and the FM cell through 1+N connections. A receiving unit(101) compares the ATM cell with the FM cell received through the 1+N connections, detects an error, and transmits a cell in which the error is not generated to the physical layer processing unit(110). An interface unit(190) transmits the 1+N ATM cells received from the transmitting unit(100) to the outside, and transmits the 1+N ATM cells received from the outside to the receiving unit(101). A connection retriever(150) judges whether the ATM cell received from the physical layer processing unit(110) and the interface unit(190) is valid, and designates a connection index about the ATM cell.

Abstract: PURPOSE: A method for controlling a permanent virtual connection(PVC) of a frame relay interlocking device is provided to connect a conventional frame relay network to an ATM network to transmit a frame data by receiving a frame relay subscriber register and connection register request and an ATM and frame relay interconnection setting request and providing an ATM switch system internal path to a frame relay subscriber. CONSTITUTION: If an ATM connection setting request IPC(Inter Processor Communication) is received from a SPVCF(Semi-permanent Point-to-Point Virtual Connection Control), it is checked whether a connection type is a VCC(Virtual Channel Connection)(404). If the connection type is not the VCC, an ATM connection setting failure response IPC is transmitted to the SPVCF(417). If the connection type is the VCC, a line number from a receiving IPC buffer, an input VPI(Virtual Path Identifier), and an input VCI(Virtual Channel Identifier) are registered in a CAM(Content Addressable Memory) and a transmission connection identifier(405). It is checked whether the generated transmission connection identifier is normal or abnormal(406). If the generated transmission connection identifier is normal, the line number is defined as a module VPI and a value for adding 100 of a hexadecimal number to the transmission connection identifier as a module VCI, and the line number, the module VPI, and the module VCI are registered in the receiving CAM for generating a receiving connection identifier(407). It is checked whether the generated receiving connection identifier is normal or abnormal(408). If the generated receiving connection identifier is normal, a line number, an output VPI, an output VCI, and a routing tag are stored in a receiving header converting table corresponding to the receiving connection identifier(409). A line number, a module VPI, a module VCI, and an FRIA(Frame Relay Interface Apparatus) number are stored in a transmitting header converting table corresponding to a transmitting connection identifier(410).
