摘要： PURPOSE: To reduce a broadcast message and to improve the efficiency of a network by arranging one or more address solving devices in the network and preventing address solving requests from being transferred to all connected terminating terminals. CONSTITUTION: An address request recognition part 1 of the arranged address solving device 5 recognizes whether a message received from a transmission terminal 6 through an ATM switch is a guide solving request message or not. An address memory part 2 retrieves a physical address corresponding to a logical address which requires address solution. An address solving response message generation part 3 generates a solving response message to which a destination physical address is added and transfers it to the transmission terminal through a message routing part 4. When it cannot be detected even if it is retrieved, it is transferred to another address solving device. When it is recognized that the received message is not the address solving request message, it is directly transferred to the transmission terminal or another device through the routing part 4.

摘要： PURPOSE: To provide various ATM exchanges provided with a multi-casting function. CONSTITUTION: Header converters 111 -11N provided in incoming highways #1 in-#Nin add tag information for specifying plural outgoing highways #1out-#Nout to inputted ATM cells, replace VCIs with internal identifiers and perform output. A switching part 12 routes the ATM cells to the plural outgoing highways based on the tag information of the ATM cells and the header converters 131 -13N provided in the respective outgoing highways convert the internal identifiers of the ATM cells to the normal VCIs and perform transmission (an internal copying system). Also, a copy server 331 is provided, plural copy cells are outputted by the copy server, one copy cell is recursively returned to the copy server, the remainder is transmitted to the outgoing highways and the copy cells are recursively routed to the copy server 331 until the required number of the copy cells are multi-casted (a recursive copy type trunk system).

摘要： PROBLEM TO BE SOLVED: To efficiently transmit cells without exceeding the limit of a band parameter by integrally controlling peak cell rate(PCR) and sustainable cell rate(SCR) on a cell transmission-side. SOLUTION: A band control part 4 judges the transmission time of the cell in a buffer 1 based on the band parameter and cell transmission history and indicates the transmission of the cells to a read control part 3. The read control part 3 reads the cells from the buffer 1 in accordance with an indication from a band control part 3 and transfers them to the cell transmission part of a cell transmission device. The most efficient cell transmission control for satisfying the conditions of PCR control and SCR control becomes possible in the transmission-side from a terminal to a network or a transmission-side from the network to the other network. Thus, cell abolishment caused by the judgment of non-conformity by an UPC/NPC(usage parameter control/network parameter control) function at the entrance of the network in a transmission destination can be prevented. Since PCR control and SCR control are integrated, buffers for accumulating the cells are not necessary to be separately provided, and the quantity of hardware can be reduced.

摘要： PURPOSE:To miniaturize individual parts by separating a line correspondence part for housing plural lines into the individual parts and a common part and processing a part of the functions of the individual parts provided for the respective lines altogether in the common part. CONSTITUTION:This exchange 10 is the exchange for performing the exchange processing of a fixed length composed of transmission data and a cell header and is provided with the line correspondence part 3 for housing the plural lines and processing information from the respective lines by a cell unit. The line correspondence part 3 is provided with the individual parts 31 and the common part 32 and the individual parts 31 are respectively connected to the plural respective housed lines and respectively perform a cell processing. The common part 32 is connected to the respective individual parts 31 and processes cells processed in the respective individual parts 31 altogether. Also, it is also valid to provide a termination part 12, a cell synchronization part 13 and an interface part 38 in the individual parts 31 as additional components.

摘要： PURPOSE:To make the size of the line associated operation device small. CONSTITUTION:A line associated operation section 3 processes information from a subscriber terminal equipment 1 connecting to a subscriber terminal equipment 1 in th unit of cells. An SDH termination section 12 terminals a synchronization digital hierarchy multiplexing hierarchically the capacity of a transmission line through which an electric signal converted by a photoelectric conversion section 11 is sent. A cell synchronization section 13 detects a synchronizing signal of a cell by applying error control to the cell based on header error control information written in a cell header. A header conversion section 18 converts a virtual path identifier written in the cell header into a virtual path identifier being a destination by referencing a conversion table 180a storing the virtual path identifier written in the cell header and a destination virtual path identifier with cross reference.

摘要： PURPOSE: To make it possible to efficiently use the band of a network line and to effectively use the resouces by receiving the information request from a user, storing the information request for the same information over the period till a determined delivery time and performing a multicast of information via a network when a delivery time comes, by an information providing origin. CONSTITUTION: An information providing origin device 21 and the information storage device 23 that each user installs are connected via a network 22. The information providing origin device 21 successively receives the requests for information A by plural users and stores these requests when the requests are performed, for instance, performs the scheduling of a delivery time to deliver the information A by the transmission of one time for these requests and transmits the information A to the network 22 by defining each request user as a destination when the delivery time reaches. In the network 22, each exchange on a transmission route performs the multicast according to destination information. The information A for which the multicast is performed is received by each user and is stored in the information storage device 23.

摘要： PURPOSE:To surely detect a faulty cell processing section or an extracted cell processing section included in a line adaptor section. CONSTITUTION:A signal sent from a subscriber terminal equipment 1 is converted into a cell by a line adaptor section 3 as a cell processing unit. The cell is transferred to a switch 4 as a cell transfer section and when the line adaptor section 3 is normal, the cell is transferred to a destination terminal equipment through the switch 4. When the line adaptor section 3 is faulty or withdrawn and no cell is sent to the switch 4, a line adaptor section interface being a detection section detects the untransmission of the cell when a cell frame signal is not continuously changed over a cell period time or over at least in the normal state.
