Claim:
1. A method for controlling traffic congestion in a network, the network comprising a plurality of interconnected nodes including a source node, intermediary nodes and a destination node, wherein at least two nodes with congestion mitigation mechanism that are connected with at least one link, said link using adaptive modulation mechanism, the method comprising: collecting at least buffer sizes at each device, type of congestion control mechanisms available, modulation used, and time stamp of each event in modulation from each node in the network; storing the at least buffer sizes at each device, type of congestion control mechanisms available, modulation used, and time stamp of each event in modulation collected from each node in the network as collected information and parameters in a database; computing network statistics from at least one of the contemplated collected information thereby reflecting the probabilities of changing modulation at a specific state, wherein computing network statistics includes calculating per radio link to reflect probabilities of changing modulation at a given specific state; computing optimal parameters of specific congestion mitigation mechanisms associated with the plurality of nodes; configuring each node's specific congestion mitigation mechanism, wherein for each mechanism the method calculates the optimal parameter configuration per node; collecting adaptive channel modulation data in predetermined intervals or ad-hoc; observing at each node if there is any change in the network condition; and updating the observed data in the data base for computing optical parameters.
