摘要： The present invention is designed such that the communication quality of a currently connected normal call is deteriorated and the transmission of the normal call is delayed in a network when an emergent call is set. As a result, the required bandwidth of the emergent call is successfully reserved. Furthermore, the present invention is designed such that a deteriorated normal call is detoured to a detour circuit to improve the communication quality of the normal call. In the detouring process, one or more detour circuits are managed for each normal call so that the possibility of a successful detour to a detour circuit can be raised. Additionally, in the normal call detouring process, a plurality of detour circuits guarantee a normal call its communication quality even if a single detour circuit is not enough to meet the required bandwidth of a normal call.

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.
