1. A method for monitoring network nodes with a minimum polling rate per round j, Rj, said method comprising the steps of:

  • polling said nodes during each round at said rate Rj where Rj equals R0 for said initial round;

    estimating congestion in said network experienced during said round j;

    adapting the polling rate for round j+1 based on said estimated congestion during round j, said adapted polling rate for round j+1 represented as Rj+1; and

    setting j=(j+1) and repeating said polling, estimating and adapting steps.
