摘要： In a load balancer preserving a function of server consistency maintenance during communications even if a terminal is a mobile terminal, identifying information specific to a mobile IP terminal is extracted from an arrival packet, and a destination server to be connected is determined based on the identifying information. Also, a home agent or a terminal is requested to notify a change of the care-of address when the care-of address of the terminal has changed, and a destination server to be connected is determined by regarding the notified care-of address as identifying information.

摘要： In a node device which is part of a communication system with a terminal and a location registering server, a node device on a receiving side transfers, to a destination node device, a received inter-node packet, based on destination terminal location information stored in its storage portion or based on a location registering server, directly or through other devices, or the destination node device notifies a former node device (on the receiving side) of an address of its own device and the destination terminal directly or through other devices. Also, the node device on the receiving side or the destination node device notify a source node device of the address of the destination node device and the destination terminal directly or through other devices, based on a predetermined address stored in the storage portion of the terminal, the node device, or the location registering server.

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： The present invention discloses a load decentralization method for decentralizing load centralized to a MAP of a hierarchical domain in a network where packets destined to mobile nodes in the network are transmitted to the mobile nodes via the MAP, in which the MAP includes a table part for managing a corresponding relation of home addresses and Care-of-Addresses of the mobile nodes in the hierarchical domain. The method includes the steps of providing a same function as the MAP to at least a portion of routers situated in the hierarchical domain of the MAP, moving one of the elements in the table part to the portion of the routers when a congestion of the MAP is detected, and actuating the portion of the routers to operate as a substitute of the MAP.

摘要： A first header converting section outputs, when partial fill cells are inputted to the first header converting section the partial fill cells, while converting a VPI of each of the partial fill cells into a value that is a unit of a multiplexing process at a short cell multiplexing section and converting a VCI of each of the partial fill cells into a value to be a CID which is to be stored in a short cell at the short cell multiplexing section. The short cell multiplexing section receives a plurality of the partial fill cells from the first header converting section to multiplex a plurality of the short cells within the partial fill cells for every VPI of the partial fill cells, and produces an AAL Type 2 cell in which the VCIs of the partial fill cells are stored as CIDs and the VPIs of the partial fill cells are stored as VCIs. A second header converting section receives the AAL Type 2 cell from the short cell multiplexing section and outputs the AAL Type 2 cell while converting the VPI/VCI of the AAL Type 2 cell into given values.

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.
