Expand description
Common interface for different congestion controllers
Required Methods§
sourcefn on_congestion_event(
&mut self,
now: Instant,
sent: Instant,
is_persistent_congestion: bool,
lost_bytes: u64,
)
fn on_congestion_event( &mut self, now: Instant, sent: Instant, is_persistent_congestion: bool, lost_bytes: u64, )
Packets were deemed lost or marked congested
in_persistent_congestion
indicates whether all packets sent within the persistent
congestion threshold period ending when the most recent packet in this batch was sent were
lost.
lost_bytes
indicates how many bytes were lost. This value will be 0 for ECN triggers.
sourcefn on_mtu_update(&mut self, new_mtu: u16)
fn on_mtu_update(&mut self, new_mtu: u16)
The known MTU for the current network path has been updated
sourcefn clone_box(&self) -> Box<dyn Controller>
fn clone_box(&self) -> Box<dyn Controller>
Duplicate the controller’s state
sourcefn initial_window(&self) -> u64
fn initial_window(&self) -> u64
Initial congestion window
Provided Methods§
sourcefn on_sent(&mut self, now: Instant, bytes: u64, last_packet_number: u64)
fn on_sent(&mut self, now: Instant, bytes: u64, last_packet_number: u64)
One or more packets were just sent
