For links that use RED gateways, there are additional trace records as follows: where := [Qap] Q=queue size, a=average queue size, p=packet droppingprobability := simulation time in seconds := valueTrace records for link dynamics are of the form: where := [v] := simulation time in seconds := [link-up | link-down] := first node address of link := second node address of link243
