Abstract

A traffic control method and apparatus for simplifying declaration of a traffic parameter and improving the utilization rate of a network having a plurality of nodes. Each of the nodes monitors a queuing delay of a cell and periodically sends a monitoring result to a network management system. The network management system stores monitoring results in a data base, estimates an average cell rate and peak cell rate by using delay information in a route, a declared peak cell rate, and the maximum data frame length obtained from the data base, decides whether to accept connection set-up, and generates a policing parameter when new connection set-up request is sent through a terminal. Each of the nodes monitors the peak cell rate and average cell rate for each connection. If an average cell rate monitoring result is extremely different from the above policing parameter request to the network management system. The network management system estimates an average cell rate again by using the database to update policing parameters.
