摘要： In a home agent for designating a transmission period of a binding update packet transmitted from a mobile node, a central processing monitor detects a usage rate of a CPU for processing accompanied by a reception of a binding update packet from the mobile node or a binding renewal message among the binding update packets, a line usage rate monitor detects a line usage rate of a receiving interface accompanied by the processing or a transmitting interface, a BC number monitor detects a binding cache number, and a calculator calculates a transmission period of the binding renewal message of the mobile node based on the thus detected CPU usage rate, line usage rate, binding cache number, and a priority table of the mobile node.

摘要： A cell processing apparatus which executes processing for switching a short-packet in AAL Type 2 cell format has a separation processing unit and a restoration processing unit. The separation processing unit splits a short packet, which has a length greater than a length L (=48) bytes capable of being accommodated in one ATM cell, into two portions, accommodates significant data containing (1) one of the short-packet portions and (2) short-packet length information, in a payload area of the first ATM cell, accommodates remaining significant data including another short-packet portion, which could not be accommodated in the first ATM cell, in a payload area of the second ATM cell, and inputs the first and second ATM cells to an ATM switch. The restoration processing unit refers to the short-packet length information that has been accommodated in the first ATM cell output from the ATM switch, restores the original short packet, the length of which exceeds L bytes, using the short packet portions that have been accommodated in respective ones of the first and second ATM cells, and sends the restored short packet to a line in the AAL Type 2 cell format.

摘要： An ATM switching apparatus applicable to a short cell including an ATM-SW outputting a cell from an output path corresponding to a cell identifier, an interface unit, a demultiplexer, and a multiplexer. The interface unit sets, when a cell storing a plurality of short cells is inputted, the cell identifier so that the cell is transmitted from ATM-SW to the demultiplexer, and outputs the cell toward the ATM-SW. The demultiplexer receives the cell and produces a plurality of partial fill cells, and outputs them, while setting an identifier of each partial fill cell, the partial fill cell is outputted. The multiplexer receives a plurality of the partial fill cells, produces a cell storing a plurality of the short cells in accordance with the identifiers and outputs the cell to the ATM-SW.

摘要： Data from an STM (Synchronous Transfer Mode) network is converted into an ATM (Asynchronous Transfer Mode) cell by an interworking facility, and the ATM cell is input to the ATM network. If the input cell corresponds to a connection which requires voice processing, a voice processing trunk within a switch performs the processes such as an echo compensation process, an encoding process, a multiplexing process, etc. The switch outputs the cell to a trunk line of the ATM network.

摘要： A short cell multiplexer includes a sequence designating unit, in which reading intervals corresponding to QOS classes are set in respective reading interval setting registers. A counter memory is stored with the number of timings at which the short cells can be read. The sequence designating unit specifies the QOS class in which the number of timings reaches the reading interval on the basis of the reading interval and the number of timings, and gives to a reading unit an indication of reading the short cell belonging to this class.

摘要： A storage unit includes an alarm state/timer table, an alarm state table, an alarm state OR-representation table, an alarm state change OR-representation table, an alarm state latch circuit, and a statistical information memory. A collection unit extracts the identifier and data from a cell that passes through a switching unit. An update unit updates associated data in the storage unit. A readout unit reads the updated data and sends it to a call processing processor. An address generation section selectively generates the address for data needing to be updated. An adjustment section forces the readout unit to wait until a cell slot arrives in which no data is updated.
