Abstract:
1. In a method for determining the load in a telecommunications network with network elements such as internal nodes and links, and with access nodes, whereby each of the access nodes consists of an ingress node and an egress node, and pass data to or from terminal devices and/or other networks whereby the internal nodes and links form paths according to routing algorithms by means of which the data packets are routed from an ingress node to an egress node, and whereby the internal nodes provide data packets with load-dependent marking, the improvement wherein the egress nodes count the data packets from the communications network and the marks contained therein by separate paths, and derive a value for the relative load along a particular path, and wherein the values derived from all egress nodes are entered as parameters into a linear equation system that describes the communications network, and its solution produces the determined relative load of the network elements, said equation system being as follows: for all i and j, whereby L n is the relevant load of an network element, m(L) is a function for calculation of mark probability between 0 and 1 for a relative load L, and M(P i,j ) is the derived relative load of a path p between an ingress node i and an egress node j, and whereby the sum of all network elements of the specific path P i,j is formed.
