Abstract
In one aspect, a method for estimating the bandwidth requirements for a transmission between an input node and an output node of a network with access controls is provided. According to the method, with respect to a time period, the sum of the value of the average bandwidth of the traffic that has been transmitted between the nodes during the time period and the weighted value of the accumulated bandwidth of the declined reservation requests is calculated. An efficient, approximate determination of the traffic matrix of the network and thus an optimal new definition of the limits for the access controls is permitted. This provides particular advantages in terms of efficiency and resources for applications in networks with a dynamic adaptation of the access controls to modified traffic situations.
