## Package net.i2p.router

The I2P router application handles the I2P network communication.

Description

Interface Summary
HandlerJobBuilder: Defines a class that builds jobs to handle a particular message - these builders are registered with the InNetMessagePool for various I2NP message types, allowing immediate queueing of a handler job rather than waiting for a polling job to come pick it up.
Job: Defines an executable task
MessageSelector: Define a mechanism to select what messages are associated with a particular OutNetMessage.
PeerManagerFacade: Manage peer references and keep them up to date so that when asked for peers, it can provide appropriate peers according to the criteria provided.
ProfileManager
ReplyJob: Defines an executable task that can be fired off in reply to a message
RouterThrottle: Gatekeeper for deciding whether to throttle the further processing of messages through the router.
Service: Define the manageable service interface for the subsystems in the I2P router
TunnelInfo: Defines the information associated with a tunnel
TunnelManagerFacade: Build and maintain tunnels throughout the network.

Class Summary
Blocklist: Manage blocking by IP address, in a manner similar to the Shitlist, which blocks by router hash.
ClientManagerFacade: Manage all interactions with clients
ClientMessage: Wrap a message either destined for a local client or received from one.
ClientMessagePool: Manage all of the inbound and outbound client messages maintained by the router.
ClientTunnelSettings: Wrap up the client settings specifying their tunnel criteria
CommSystemFacade: Manages the communication subsystem between peers, including connections, listeners, transports, connection keys, etc.
DummyClientManagerFacade: Manage all interactions with clients
DummyNetworkDatabaseFacade
DummyPeerManagerFacade: Manage peer references and keep them up to date so that when asked for peers, it can provide appropriate peers according to the criteria provided.
DummyTunnelManagerFacade: Build and maintain tunnels throughout the network.
InNetMessagePool: Manage a pool of inbound InNetMessages.
JobImpl: Base implementation of a Job
JobQueue: Manage the pending jobs according to whatever algorithm is appropriate, giving preference to earlier scheduled jobs.
JobQueueRunner: a do run run run a do run run
JobStats: glorified struct to contain basic job stats
JobTiming: Define the timing requirements and statistics for a particular job
KeyManager: Maintain all of the key pairs for the router.
LeaseSetKeys: Wrap up the keys given to the router when a destination connects to it
MessageHistory: Simply act as a pen register of messages sent in and out of the router.
MessageReceptionInfo: Wrap up the details of how a ClientMessage was received from the network
MessageStateMonitor: Keep track of the inbound and outbound messages in memory.
MessageValidator: Singleton to manage the logic (and historical data) to determine whether a message is valid or not (meaning it isn't expired and hasn't already been received).
MultiRouter: Fire up multiple routers in the same VM, all with their own RouterContext (and all that entails).
MultiRouterBuilder: Build a set of config files suitable for use by the multirouter as a simulation, as well as a pair of scripts for running the simulation.
NetworkDatabaseFacade: Defines the mechanism for interacting with I2P's network database
OutNetMessage: Wrap up an outbound I2NP message, along with the information associated with its delivery and jobs to be fired off if particular events occur.
OutNetMessagePool: Maintain a pool of OutNetMessages destined for other routers, organized by priority, expiring messages as necessary.
PeerSelectionCriteria: Defines the criteria for selecting a set of peers for use when searching the PeerManager
PersistentKeyRing: ConcurrentHashMap with backing in the router.config file.
Router: Main driver for the router.
RouterClock: Alternate location for determining the time which takes into account an offset.
RouterContext: Build off the core I2P context to provide a root for a router instance to coordinate its resources.
RouterDoSThrottle: Deprecated. unused
RouterLaunch: This is the class called by the runplain.sh script on linux and the i2p.exe launcher on Windows.
RouterThrottleImpl: Simple throttle that basically stops accepting messages or nontrivial requests if the jobQueue lag is too large.
RouterVersion: Expose a version string
RouterWatchdog: Periodically check to make sure things haven't gone totally haywire (and if they have, restart the JVM)
Shitlist: Routers are shitlisted only if none of our transports can talk to them or their signed router info is completely screwy.
Shitlist.Entry
StatisticsManager: Maintain the statistics about the router
TunnelPoolSettings: Wrap up the settings for a pool of tunnels (duh)

## Package net.i2p.router Description

The I2P router application handles the I2P network communication.

It encompasses sending and receiving messages, building up tunnels, encrypting and decrypting (on multiple levels) where applicable, and so on.
