Method Codel

core/utils/codel.h:71–81

Takes a drop function which is a function that should take a dropped object and handle it removing the object potentially including freeing the object. If there is no need to handle a dropped object, NULL can be passed instead. target is the target delay in nanoseconds and the window is the buffer time u in nanosecond before changing into drop state.

  // target is the target delay in nanoseconds and the window is the buffer time u
  // in nanosecond before changing into drop state.
  Codel(void (*drop_func)(T)= NULL, size_t max_entries=0, uint64_t target = kDefaultTarget,
      uint64_t window = kDefaultWindow)
      : delay_target_(target),
        window_(window),
        time_above_target_(0),
        next_drop_time_(NanoSecondTime() + window),
        drop_count_(0),
        dropping_(0),
        max_size_(max_entries),
        queue_(),
        drop_func_(drop_func) { }

  // deconstructor that drops all objects still left in the internal queue.
