摘要： Control messages for securing a communication quality are exchanged via a dedicated connection within an ATM network when a sending terminal in an IP network delivers data to a receiving terminal in another IP network via the ATM network. A resource reservation message sent from the receiving terminal is parsed by a boundary device located at the boundary between the IP and the ATM network, and a data transfer connection is established within the ATM network based on the information of the resource reservation message.

摘要： In a first UPC, a PCR is set as a monitor rate for each connection. If a transfer rate of a cell exceeds the PCR set for the connection, the cell is discarded. In a second UPC, an ACR is set as a monitor rate for each connection. If the transfer rate of the cell exceeds the ACR set for the connection, a lower priority is assigned to that cell. Additionally, with a configuration where one UPC monitors a varying rate, a parameter change process is controlled by obtaining a time between a passage time of a detected B-RM cell and an arrival of a user cell and comparing the obtained time with maximum and minimum delay standard values. A parameter table including some parameters is provided. A header of an arrived cell in a forward direction is extracted, and it is determined whether or not the arrived cell is a violation cell using the leaky bucket algorithm, etc. If the arrived cell is a violation cell, it is discarded. An RM cell in a backward direction is received and extracted, and the parameter table is updated by calculating the minimum cell interval, etc. based on data included in a payload of the RM cell.

摘要： A boundary apparatus on the transmission side provided on the boundary between an IP network accommodating a transmitting terminal and an ATM network separates the requests for bandwidth which are received from receiving terminals via boundary apparatuses on the reception side into a plurality of groups on the basis of a required bandwidth, establishes a point-multipoint connection between the boundary apparatus on the transmission side and each of the boundary apparatuses on the reception side for each group, and transmits the data from the transmitting terminal to each of the receiving terminals via the connection. When there is a change in the number of the requests for bandwidth due to the delivery of a new request for bandwidth or the interruption of a flow of requests, the boundary apparatus on the transmission side calculates the effective bandwidth allocation ratio of the group in which there is a change in the number of the requests for bandwidth, and if the effective bandwidth allocation ratio is not more than a preset value, the boundary apparatus separates the requests belonging to the group into two groups, and establishes a connection for each group.

摘要： An ATM connection is a virtual communication path specified by VPI/VCI. A plurality of ATM connections that are directed to the same output line is defined as an ATM connection group. A connection UPC (Usage Parameter Control) facility is provided for each of the ATM connections and a connection group UPC facility is provided for the ATM connection group. The connection UPC facilities and the connection group UPC facility are operated in either the monitor mode or the control mode. In the monitor mode, when the rate of flow of packets into a network exceeds a threshold, a control unit is informed of it, but cells are allowed to enter the network as they are. In the control mode, when the rate of flow of cells into the network exceeds the threshold, cells the flow rate of which exceeds the threshold are discarded.

摘要： An L bit for notifying another router of whether a self-router belongs to a connection-oriented network is newly provided in the options field of a conventional OSPF packet and the OSPF packet, including L bit is transmitted to another router. In this way, each router belonging a network can automatically recognize a router belonging to a connection-oriented network by detecting L bit. Then, by generating a routing tree, a connection-oriented network device can be identified in the routing tree and mapping between a connection-oriented network and a connectionless network can be performed in an edge device.
