Abstract

A network comprises routers, wherein at least some of the routers are configured to receive a number of datastreams and to output an aggregated datastream. Subject to the precondition that a limiting bit rate ri and a number of burst bits bi can be quoted for each datastream i supplied to a router from outside the network, such that the number Aiin(t1, t2) of data bits which are received at an input of the routers, between a time t1 and a later time t2, satisfies the relationship Aiin(t1, t2)≦ri*(t2−t1)+bi, each router j controls the output of data packets in the aggregated datastream ia(j) such that, for a limiting bit rate Ria(j)ag and for a predeterminable burst bit number Bia(j), the number Aia(j)out(t1, t2) of data bits output in the aggregated datastream ia(j) satisfies the relationship Aia(j)out(t1, t2)≦Ria(j)ag*(t2−t1)+Bia(j), wherein Ria(j)ag and Bia(j) are independent of the observation time period.
