Abstract

A node circuit for connecting a plurality of input lines to a plurality of output lines in a packet switching system. The circuit includes a switching network whose connections are stored as a link table whose entries are determined by a traffic control device based on estimated traffic information included in a signalling packet provided at the initial stage of a call. The traffic control device is coupled to the switching network through a switching control device. The traffic control device computes a necessary available traffic carrying capacity of an output line to be selected for the call. The device compares this value to the actual available traffic carrying capacity of the output lines which lead to the destination terminal to determine the most appropriate output line and stores the result in the link table. A traffic counting device is also provided in order to obtain a count of the actual traffic of the call. this count is then utilized as a replacement for the estimated traffic information by the traffic control device in determining the entries of the link table when a subsequent call from the same origination terminal to the same destination terminal and with the same estimated traffic information is received by the node circuit.
