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 network topology information and various parameters from each nodes in the network, wherein the collected information includes length of links, buffer sizes at each device, type of congestion control mechanisms available, modulation used, time stamp of each event in modulation; storing the 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 er 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; and configuring each node's specific congestion mitigation mechanism, wherein for each mechanism the method calculates the optimal parameter configuration per node.
