Package net.i2p.client.streaming.impl
Implementation of a TCP-like (reliable, authenticated, in order) set of sockets for communicating over the IP-like (unreliable, unauthenticated, unordered) I2P messages. This is the streaming implementation (moved for ticket #1135 to here). For the API (which you probably want), see ministreaming. Clients should not need to access anything in this package directly. Use the interfaces and factory in net.i2p.streaming. Note that this class is split across two jars, streaming.jar and ministreaming.jar. The interfaces and some code are in ministreaming.jar, but the real work gets done in streaming.jar. Clients must have both jars in their classpath. Most clients will require (only) streaming.jar, ministreaming.jar, and i2p.jar in their classpath to communicate with the router.

Interface Summary Interface Description ConnectionManager.PingNotifier The callback interface for a pong.MessageOutputStream.DataReceiver Define a component to receive data flushed from this streamMessageOutputStream.WriteStatus Define a way to detect the status of a writeTaskScheduler Coordinates what we do 'next'. -
Class Summary Class Description Connection Maintain the state controlling a streaming connection between two destinations.ConnectionDataReceiver Receive data from the MessageOutputStream, build a packet, and send it through a connection.ConnectionHandler Receive new connection attempts Use a bounded queue to limit the damage from SYN floods, router overload, or a slow clientConnectionManager Coordinate all of the connections for a single local destination.ConnectionOptions Define the current options for the con (and allow custom tweaking midstream) TODO many of these are not per-connection options, and should be migrated somewhere so they aren't copied for every connectionConnectionPacketHandler Receive a packet for a particular connection - placing the data onto the queue, marking packets as acked, updating various fields, etc.ConnThrottler Count how often we have received an incoming connection This offers basic DOS protection but is not a complete solution.I2PServerSocketFull Bridge to allow accepting new connectionsI2PSocketFull Bridge between the full streaming lib and the I2PSocket APII2PSocketManagerFull Centralize the coordination and multiplexing of the local client's streaming.I2PSocketOptionsImpl Define the configuration for streaming and verifying data on the socket.MessageHandler Receive raw information from the I2PSession and turn it into Packets, if we can.MessageInputStream Stream that can be given messages out of order yet present them in order.MessageOutputStream A stream that we can shove data into that fires off those bytes on flush or when the buffer is full.Packet This contains solely the data that goes out on the wire, including the local and remote port which is embedded in the I2CP overhead, not in the packet itself.PacketHandler receive a packet and dispatch it correctly to the connection specified, the server socket, or queue a reply RST packet.PacketLocal This is the class used for outbound packets.PacketQueue Queue out packets to be sent through the session.PcapWriter Write a standard pcap file with a "TCP" packet that can be analyzed with standard tools such as wireshark.RetransmissionTimer Per-destination timerSchedulerChooser Examine a connection's state and pick the right scheduler for it.SchedulerClosed Scheduler used for after both sides have had their close packets ACKed, but the final timeout hasn't passed.SchedulerClosing Scheduler used for after both SYNs have been ACKed and both sides have closed the stream, but either we haven't ACKed their close or they haven't ACKed ours.SchedulerConnectedBulk Scheduler used for after our SYN has been sent and ACKed but one (or more) sides haven't closed the stream yet.SchedulerConnecting Scheduler used once we've sent our SYN but it hasn't been ACKed yet.SchedulerDead Scheduler used for after the final timeout has passed or the connection was reset.SchedulerHardDisconnected Scheduler used after we've locally done a hard disconnect, but the final timeout hasn't passed.SchedulerImpl Base schedulerSchedulerPreconnect Scheduler used for locally created connections where we have not yet sent the initial SYN packet.SchedulerReceived Scheduler used after receiving an inbound connection but before we have sent our own SYN.SimpleBandwidthEstimator A Westwood+ bandwidth estimator with a first stage anti-aliasing low pass filter based on RTT, and the time-varying Westwood filter based on inter-arrival time.StandardServerSocket Bridge to I2PServerSocket.StandardSocket Bridge to I2PSocket.TCBShare Share important TCP Control Block parameters across Connections to the same remote peer. -
