Abstract: PURPOSE: A cross-point element structure for an ATM(Asynchronous Transfer Node) switch is provided to implement a switch having a self-routing function, remove necessity of an additional function for copying a cell, and prevent a time slot from being wasted when the cell is copied. CONSTITUTION: Output-group address inputs(AGN(15:0)) represent the output port grouping address information inputted from an external output address allocation part. Output-group address outputs(AGN(15:0)) are transferred to next switch element via a switch element. A path set status input(SIN) represents a path set status of an upper switch element in the same column. A path set status output(SOUT) informs a path set status output to a lower switch element in the same column. Input-cell address inputs(RGN(15:0)) is received by switch elements. Modification address outputs(MGN(15:0)) transfers the path set status of a switch element to a right switch element. A connection designator(GIN) transmits timing information in order to illustrate a final status.

Abstract: PURPOSE: The apparatus for removing lost packet data in order to prevent traffic congestion in an asynchronous transfer mode(ATM) system is provided to enable a stable ATM operation, and to guarantee the service with good quality for various types of service traffic, by preventing the traffic congestion in the system using minimum hardware logic. CONSTITUTION: A received cell processor(B2) generates a connection memory address(S2) related to a received cell(S1), a packet start signal and a packet end signal(S3). A connection table managing part(B3) manages an unnecessary cell designating signal(S5) and a negotiation parameter(S4). A negotiation violation checking part(B4) detects the cell that excesses a negotiated traffic rate, and sets the signal(S5) according to the result of the detection. An unnecessary cell processor(B5) combines the unnecessary cell designating signal(S5) received from the part(B3) with a negotiation violation signal(S6) applied from the part(B4), and thereby removes the unnecessary cell.

Abstract: PURPOSE: An apparatus for controlling connection acceptance to support multiple qos and method thereof are provided, considering properly traffic parameters such as peak cell rate, sustained cell rate, maximum burst size, minimum cell rate, etc., latency characteristics, service quality grades, etc., according to traffic kinds. CONSTITUTION: A traffic kind classification device(101) discriminates what kind of traffic characteristics the connection requested traffic has. A service quality grade classification device(102) determines a service quality grade that a connection requested variable bit rate(VBR) belongs to. An equivalent band calculator(103-105) gets equivalent bands to meet service qualities, based on the value of a peak cell rate(PCR). An equivalent band calculator(106) gets equivalent bands, based on the value of a minimum cell rate(MCR). A connection acceptance determination device(107) judges whether so much bands to approve the connection of the connection requested traffic remains.

Abstract: PURPOSE: A method for searching, creating and deleting a node in an MIT(Management Information Tree) using a multiple-balanced tree structure is provided to reduce a process load that is generated if the MIT is represented as a binary tree structure. CONSTITUTION: An input of a distinguished name as a search target is received(100). A root node of the MIT is searched, and then it is determined whether the root node exists(101). If the root node does not exist, a search failure is declared and a search procedure is ended(102). A child sub-tree of the root node is searched if the root node exists(103). If the child sub-tree thereof exists, a node corresponding to a relative distinguished name is searched in the child sub-tree(104). It is determined whether the relative distinguished name of the searched node is a final relative distinguished name which forms the distinguished name(105). If the relative distinguished name thereof is the final one, a value of the searched node is reported(106). If the relative distinguished name thereof is not the final one, the child sub-tree is searched again, and then the node corresponding to the relative distinguished name is searched repeatedly(102-105).
