Abstract: A method of operating a communication system comprises receiving a plurality of traffic, processing each traffic of the plurality of traffic to determine if a delay of the traffic exceeds a delay limit, discarding the traffic if the delay exceeds the delay limit, retaining the traffic if the delay does not exceed the delay limit, incrementing a late counter from a base amount of the late counter when the delay exceeds the delay limit, incrementing a retained counter from a base amount of the retained counter when the delay does not exceed the delay limit, returning the late counter to the base amount of the late counter when the delay does not exceed the delay limit and when the delay of a previous traffic exceeded the delay limit, clearing the retained counter to the base amount of the retained counter when the delay exceeds the delay limit and when the previous traffic did not exceed the delay limit, increasing the delay limit when the late counter exceeds a late limit, and decreasing the delay limit when t
