ESTIMATION OF BANDWIDTH REQUIREMENTS IN A COMMUNICATIONS NETWORK WITH ACCESS CONTROLS

摘要

The invention relates to a method for estimating the bandwidth requirements for a transmission between an input node (i) and an output node (k) of a network with access controls. According to said 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 (i, k) during said time period and the weighted value of the accumulated bandwidth of the declined reservation requests is calculated. The invention permits an efficient, approximate determination of the traffic matrix of the network and thus an optimal new definition of the limits for the access controls. 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.
