Abstract: This invention is to enable appropriate routing based on transition prediction of network traffic. This routing control method includes: reading out predicted utilization transition data (e.g. utilization rate, or utilized bandwidth) associated with a received connection set-up request from a predicted utilization transition data storage storing said predicted utilization transition data for each resource (e.g. links between routers, or server) in a network in future; and selecting a resource satisfying a predetermined condition based on the read predicted utilization transition data. Thus, by using said predicted utilization transition data, an appropriate resource is identified in accordance with future time transition of the resource utilization rate, for example, and thereby, appropriate routing is possible.

Subsequently, the statistical-data collecting-and-providing apparatus collects statistical data based on the thus-received statistical-data acquisition criterion. Thereafter, the statistical-data collecting-and-providing apparatus delivers the thus-collected statistical data to a service-providing application server, which is the notification destination received through the statistical-data-acquisition-criterion setting interface.

Abstract: 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.
