Abstract
A method is described to estimate the current datapacket rate CCR.sub.i called herein current cell rate, of a connection out of a plurality of connections which are carrying datapackets via a multiplexed transmission channel in a communication network. The method includes the steps of storing in a buffer (B) incoming datapackets of the connections, determining the total number of datapackets BC.sub.TO in the buffer (B), determining the number of datapackets of the connection BC.sub.i in the buffer (B), measuring an aggregate input datapacket rate C.sub.IN of the buffer and estimating the current datapacket rate CCR.sub.i via the formulae: ##EQU1##
