Interface Summary

Interface	Description
CongestionControl	Strategy for applying congestion control to determine the receiver window length of the Status Messages.
CongestionControlSupplier	Supplier of CongestionControl algorithm implementations to be used by receivers.
DriverManagedResource	Common behaviour supported for driver resources such as publications and images.
FeedbackDelayGenerator	Feedback delay generator.
FlowControl	Strategy for applying flow control to the Sender on each stream.
FlowControlSupplier	Supplier of FlowControl strategies to be employed by senders for publications.
LossHandler	Handler for dealing with detected loss on a message stream.
NameResolver	Interface to allow resolving a name to an InetAddress.
ReceiveChannelEndpointSupplier	Supplier of channel endpoints which extend ReceiveChannelEndpoint to add specialised behaviour for the receiver.
RetransmitSender	Handler for sending a retransmit
SendChannelEndpointSupplier	Supplier of channel endpoints which extend SendChannelEndpoint to add specialised behaviour for the sender.
Subscribable	Stream source that can be observed by subscribers which identify themselves the position they have read up to.
TerminationValidator	Validate if the driver should terminate based on the provided token.

Class Summary

Class	Description
AbstractMinMulticastFlowControl	Abstract minimum multicast sender flow control strategy.
Configuration	Configuration options for the MediaDriver.
DataPacketDispatcher	Handling of dispatching data packets to PublicationImages streams.
DefaultAllowTerminationValidator	Default implementation of TerminationValidator that always allows termination.
DefaultCongestionControlSupplier	Supplier of congestion control algorithms which is aware of channel URI params otherwise defaults to StaticWindowCongestionControl.
DefaultDenyTerminationValidator	Default implementation of TerminationValidator that always denies termination.
DefaultMulticastFlowControlSupplier	Default supplier of FlowControl strategies for multicast streams which supports defining the strategy in the channel URI as a priority over Configuration.MULTICAST_FLOW_CONTROL_STRATEGY_PROP_NAME.
DefaultNameResolver	Use the default host name resolver via InetAddress.
DefaultReceiveChannelEndpointSupplier	Supply the default implementation of the ReceiveChannelEndpoint.
DefaultSendChannelEndpointSupplier	Supply the default implementation of the SendChannelEndpoint.
DefaultUnicastFlowControlSupplier	Default supplier of FlowControl strategies for unicast streams via Configuration.UNICAST_FLOW_CONTROL_STRATEGY_PROP_NAME.
DriverConductor	Driver Conductor that takes commands from publishers and subscribers and orchestrates the media driver.
DriverConductorProxy	Proxy for sending commands to the DriverConductor.
IpcPublication	Encapsulation of a stream used directly between publishers and subscribers for IPC over shared memory.
LossDetector	Detecting and handling of gaps in a message stream.
MaxMulticastFlowControl	Default multicast sender flow control strategy.
MaxMulticastFlowControlSupplier	Supplier of MaxMulticastFlowControl strategy implementations.
MediaDriver	Main class for JVM-based media driver
MediaDriver.Context	Context for the MediaDriver that can be used to provide overrides for Configuration.
MinMulticastFlowControl	Minimum multicast sender flow control strategy.
MinMulticastFlowControlSupplier	Supplier of MinMulticastFlowControl strategy implementations.
NetworkPublication	Publication to be sent to connected subscribers.
OptimalMulticastDelayGenerator	Feedback delay used for NAKs as well as for some retransmission use cases.
PreferredMulticastFlowControl	Deprecated Use TaggedMulticastFlowControl instead
PreferredMulticastFlowControlSupplier	Deprecated Use TaggedMulticastFlowControlSupplier instead
PublicationImage	State maintained for active sessionIds within a channel for receiver processing
Receiver	Receiver agent for JVM based media driver, uses an event loop with command buffer
RetransmitHandler	Tracking and handling of retransmit request, NAKs, for senders, and receivers.
Sender	Agent that iterates over NetworkPublications for sending them to registered subscribers.
StaticDelayGenerator	Delay generator that simply returns a constant value (such as 0)
StaticWindowCongestionControl	Congestion control algorithm which uses the min of MediaDriver.Context.initialWindowLength() or half a term length as a static window.
SubscriptionLink	Subscription registration from a client used for liveness tracking
TaggedMulticastFlowControl	Minimum multicast sender flow control strategy only for tagged members identified by a receiver tag or ASF key.
TaggedMulticastFlowControlSupplier	Supplier of TaggedMulticastFlowControl implementation strategies.
UnicastFlowControl	Default unicast sender flow control strategy.

Enum Summary

Enum	Description
ThreadingMode	Threading mode to be employed by the Agents in the MediaDriver.

Package io.aeron.driver Description

The MediaDriver manages sending and receiving from the underlying media and handling request from the Aeron clients. The media driver can run in-process, or out of process, from the Aeron clients.
