    • The invention concerns a method for determining the load in a communication network (1) provided with network elements such as internal nodes (5, 6, 9) and links (10, 11, 12) and with access nodes (2, 3, 4), respectively, comprising an input node (21, 31, 41) and an output node (22, 32, 42), which derive and transfer data packets from connected terminals and/or other networks. The internal nodes and links form paths according to routing algorithms and the internal nodes provide data packets with a load-dependent marking (M). According to the invention, the output nodes separately count up the data packets arriving from the communication network and the markings contained therein according to paths, deriving therefrom a value for the relative load along the respective path, and the values derived from all output nodes are introduced as parameters into a system of equations describing the communication network with the internal nodes and access nodes, whereby the solution thereof occurs in a determined relative network element load. The respectively determined relative load can be corrected according to other determined incoming data throughput rates and overall data throughput rates of the network elements. Different marking algorithms can also be used by the internal nodes according to information contained in the header of the data packets.
    • 本发明涉及一种用于确定通信网络(1)中负载的方法,所述通信网络(1)具有诸如内部节点(5,6,11)和链路(10,11,12)之类的网络元件以及接入节点(2,3,4) ),其分别包括从连接的终端和/或其他网络导出和传送数据分组的输入节点(21,31,41)和输出节点(22,32,42)。 内部节点和链路根据路由算法形成路径,内部节点为负载依赖标记(M)提供数据包。 根据本发明,输出节点分别对从通信网络到达的数据分组和根据路径包含的标记进行计数,从而导出沿着相应路径的相对负载的值,并且从所有输出节点导出的值是 作为参数引入描述与内部节点和接入节点的通信网络的方程组,由此其解决方案以确定的相对网元负载发生。 可以根据其他确定的输入数据吞吐率和网络元件的总体数据吞吐速率来校正分别确定的相对负载。 不同的标记算法也可以根据包含在数据包头中的信息由内部节点使用。
