Definitions
- the object of the present invention is therefore to provide a method for determining the load in a
- a prerequisite for a reliable determination of the load is that the nodes carry out the frequency of the markings according to a constantly and strictly monotonically increasing function of the load.
- Equation is applied e capacity of the network element, 'Ln the determined relative load, t. , the transmitted data rate along a
- Fig. 1 shows schematically a communication network
- markings contain, for example, the data packets which are routed from the input node 21 via the internal nodes 5, 6 to the output node 32. If the internal nodes 5, 6 and their connections to one another and to the nodes 21 and 32 are overloaded, more of the data packets to be sent from the input node 21 to the output node 32 are routed via the internal nodes 8, 9.
- the markings M contained in the data packets received by the input node 21 are counted in the output node 32 in a predetermined time period.
- the bytes and the data packets are counted, which are transmitted from the input node 21 to the output node 32 in the predetermined time.
- the number of markers divided by the number of data packets gives a good measure of the load on the communication network with regard to the transmission between the input node 21 and the output node 32.
- the marking takes place with a probability m (L), where L is a relative load. For each pair connected by a path
- Both the relative load L and the overall data rate are measured regularly - for example at intervals of a few seconds.
- the newly determined values Ln and Un as well as the previous values La and Ua are used for each network element to form the corrected load Lk according to the following equation:
- the equations for calculating the marking rates can be derived as follows, where P is a number of data packets for which the relative number of marked data packets - ie the marking rate - is to be calculated. Furthermore, N is the number of ECT01, ECT10 and CE data packets. The other data packets (P-N) are irrelevant.
