Generic means of SACK/NACK transmission for partially or fully received messages
Base queue for messages not yet packetized
Blocking thread that is given peers by the inboundFragment pool, sending out any outstanding ACKs.
Since the TimedWeightedPriorityMessageQueue.add() was disabled by jrandom in UDPTransport.java on 2006-02-19, and the choke/unchoke was disabled at the same time, all of TWPMQ is pointless, so just do this for now.
Coordinate the establishment of new sessions - both inbound and outbound.
Data for a new connection being established, where the remote peer has initiated the connection with us.
Hold the raw data fragments of an inbound message.
Keep track of inbound and outbound introductions.
Get the MTU for the network interface of an address.
Data for a new connection being established, where we initiated the connection with a remote peer.
Coordinate the outbound fragments and select the next one to be built.
Maintain the outbound fragmentation for resending, for a single message.
Blocking thread to grab new messages off the outbound queue and plopping them into our active pool.
Big ol' class to do all our packet formatting.
Class for passing multiple fragments to buildPacket()
Pull inbound packets from the inbound receiver's queue, figure out what peer session they belong to (if any), authenticate and decrypt them with the appropriate keys, and push them to the appropriate handler.
Blocking thread to grab new packets off the outbound fragment pool and toss 'em onto the outbound packet queues.
Contain all of the state about a UDP connection to a peer.
Entry points are runTest() to start a new test as Alice, and receiveTest() for all received test packets.
Track the state of a peer test.
Unique ID for a peer - its IP + port, all bundled into a tidy obj.
Comparators for various columns
Weighted priority queue implementation for the outbound messages, coupled with code to fail messages that expire.
basic helper to parse out peer info from a udp address
Coordinate the low-level datagram socket, creating and managing the UDPSender and UDPReceiver.
Basic delivery unit containing the datagram.
To read a packet, initialize this reader with the data and fetch out the appropriate fields.
Lowest level component to pull raw UDP datagrams off the wire as fast as possible, controlled by both the bandwidth limiter and the router's throttle.
Lowest level packet sender, pushes anything on its queue ASAP.
The SSU transport
The UDP transport (also known as 'SSU transport') allows passing I2P messages on top of UDP.
