Abstract: Based on flowconservation law, a network traffic monitornode selection algorithm is proposed to effectively select the network traffic monitornode. The problem of the monitornode selection is regarded as a problem to find out the weak vertex cover of a graph. This algorithm marks all of the network nodes with the triple tags and recursively compares and replaces those triple tags. The network traffic monitornodes are selected by the final triple tags. Simulations show that the algorithm needs not to know the whole network topology. It can dynamically eliminate the unavailable network nodes to effectively solve the problem of the monitornode selection.
