See: Description
| Interface | Description |
|---|---|
| FragmentHandler.DefragmentedReceiver |
Receive messages out of the tunnel endpoint.
|
| IVValidator |
Provide a generic interface for IV validation which may be implemented
through something as simple as a hashtable or more a complicated
bloom filter.
|
| TunnelGateway.QueuePreprocessor |
Interface for preprocessing queued tunnel messages.
|
| TunnelGateway.Receiver |
Interface for receiving encrypted tunnel data.
|
| TunnelGateway.Sender |
Interface for sending preprocessed tunnel data.
|
| Class | Description |
|---|---|
| BatchedPreprocessor |
Batching preprocessor that will briefly delay the sending of a message if it
doesn't fill up a full tunnel message, in which case it queues up an additional
flush task.
|
| BatchedRouterPreprocessor |
Honor the 'batchFrequency' tunnel pool setting or the 'router.batchFrequency'
router config setting, and track fragmentation.
|
| BloomFilterIVValidator |
Manage the IV validation for all of the router's tunnels by way of a big
decaying bloom filter.
|
| DummyValidator |
IV validator that accepts all initialization vectors without validation.
|
| FragmentedMessage |
Gather fragments of I2NPMessages at a tunnel endpoint, making them available
for reading when complete.
|
| FragmentHandler |
Handle fragments at the endpoint of a tunnel, peeling off fully completed
I2NPMessages when they arrive, and dropping fragments if they take too long
to arrive.
|
| HopConfig |
Defines the general configuration for a hop in a tunnel.
|
| HopProcessor |
Take a received tunnel message, verify that it isn't a
duplicate, and translate it into what the next hop will
want.
|
| InboundEndpointProcessor |
Receive the inbound tunnel message, removing all of the layers
added by earlier hops to recover the preprocessed data sent
by the gateway.
|
| InboundGatewayProcessor |
Override the hop processor to seed the message with a random
IV.
|
| InboundGatewayReceiver |
Handle messages at the IBGW.
|
| InboundMessageDistributor |
When a message arrives at the inbound tunnel endpoint, this distributor
honors the instructions (safely)
|
| InboundSender |
Receive the preprocessed data for an inbound gateway, encrypt it, and forward
it on to the first hop.
|
| OutboundGatewayMessage |
Stores all the state for an unsent or partially-sent message
|
| OutboundGatewayProcessor |
Turn the preprocessed tunnel data into something that can be delivered to the
first hop in the tunnel.
|
| OutboundMessageDistributor |
When a message arrives at the outbound tunnel endpoint, this distributor
honors the instructions.
|
| OutboundReceiver |
We are the outbound gateway - we created this outbound tunnel.
|
| OutboundSender |
Receive the preprocessed data for an outbound gateway, encrypt all of the
layers, and forward it on to the first hop.
|
| OutboundTunnelEndpoint |
We are the end of an outbound tunnel that we did not create.
|
| PendingGatewayMessage |
Stores all the state for an unsent or partially-sent message
|
| PumpedTunnelGateway |
This class represents a tunnel gateway with multiple hops that accepts messages,
then coalesces and fragments them before sending them down the tunnel.
|
| ThrottledPumpedTunnelGateway |
Specialized pumped tunnel gateway for inbound gateways (IBGWs) that throttles messages
by checking bandwidth usage before queuing them.
|
| TrivialPreprocessor |
Do the simplest thing possible for preprocessing - for each message available,
turn it into the minimum number of fragmented preprocessed blocks, sending
each of those out.
|
| TunnelCreatorConfig |
Coordinate the info that the tunnel creator keeps track of, including what
peers are in the tunnel and what their configuration is
See PooledTunnelCreatorConfig for the non-abstract class
|
| TunnelDispatcher |
Handle the actual processing and forwarding of messages through the various tunnels.
|
| TunnelGateway |
Serve as the gatekeeper for a tunnel, accepting messages, coalescing and/or
fragmenting them before wrapping them up for tunnel delivery.
|
| TunnelGatewayPumper |
TunnelGatewayPumper runs a pool of threads that process PumpedTunnelGateway instances which need
messages pushed through preprocessing and sending.
|
| TunnelGatewayZeroHop |
Serve as the gatekeeper for a tunnel with no hops, either inbound or outbound.
|
| TunnelParticipant |
Participates in a tunnel at an intermediate hop (not gateway or endpoint).
|
| Enum | Description |
|---|---|
| TunnelDispatcher.Location |
Location in the tunnel for RED logic
|
Core tunnel management, message processing, and encryption for I2P's anonymous routing system.
This package provides the complete implementation of I2P's tunnel system, which forms the backbone of anonymous communication in the I2P network. Tunnels provide bidirectional, encrypted paths through multiple routers, ensuring both anonymity and message delivery reliability.
