CongestionController class - udx library

Constructors

CongestionController.new({required PacketManager packetManager, int? initialCwnd})

cwnd → int: The current congestion window size in bytes.
no setter
hashCode → int: The hash code for this object.
no setterinherited
inflight → int: The number of bytes in flight.
no setter
isInRecoveryForTest → bool: Flag indicating if the controller is in a fast recovery phase.
no setter
latestRttForTest → Duration: The latest RTT sample, exposed for testing.
no setter
maxPtoRetries ↔ int: Maximum number of PTO retries before considering connection issues
getter/setter pair
minRtt → Duration: The minimum RTT observed so far.
no setter
onFastRetransmit ↔ void Function(int sequence)?: Callback for fast retransmit.
getter/setter pair
onProbe ↔ void Function()?: Callback for when a probe packet should be sent.
getter/setter pair
pacingController → PacingController: The packet pacer.
final
packetManager → PacketManager: final
pto → Duration: The Probe Timeout (PTO) duration.
no setter
rttVar → Duration: The RTT variation.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
smoothedRtt → Duration: The smoothed round-trip time.
no setter
ssthresh → int: The slow start threshold.

onPacketAcked(int bytes, DateTime sentTime, Duration ackDelay, bool isNewCumulativeAck, int currentFrameLargestAcked) → void: Called when a packet is acknowledged. bytes is the size of the acknowledged packet. sentTime is the time the acknowledged packet was sent. ackDelay is the delay the receiver waited before sending the ACK. isNewCumulativeAck true if the ACK frame advanced the highest cumulative ACK point. currentFrameLargestAcked the 'largest_acked' value from the current ACK frame.
onPacketLost(int bytes, List<UDXPacket> lostPackets) → void: Called when a packet is considered lost.
onPacketSent(int bytes) → void: Called when a packet is sent.
processDuplicateAck(int frameLargestAcked) → void: Called by UDXStream when an ACK frame is received that does not advance the _highestProcessedCumulativeAck. frameLargestAcked is the 'largest_acked' value from this duplicate ACK frame.
setRttVar(Duration rttVar) → void: Sets the RTT variation for testing purposes.
setSmoothedRtt(Duration rtt) → void: Sets the smoothed RTT for testing purposes.
toString() → String: A string representation of this object.
