net.i2p  
net.i2p.client Implements the base I2P SDK for developing applications that communicate through I2P.
net.i2p.client.datagram Provides a standard way for reading and writing messages transferred over I2P so that the recipient has an authenticated mechanism to reply to it.
net.i2p.client.naming Provides a standard way for querying the local naming service to resolve a name into a Destination (without the complexity of JNDI).
net.i2p.crypto  
net.i2p.data These classes define the common data structures used by the various I2P protocols.
net.i2p.data.i2cp The Invisible Internet Client Protocol (I2CP) allows applications simplified access to the I2P network without requiring them to deal with the issues involved with the Invisible Internet Network Protocol (I2NP).
net.i2p.stat These classes define the statistics package used extensively throughout the I2P router - both for adaptive operation of the router and for debugging.
net.i2p.time  
net.i2p.util These classes define the several useful utilities used throughout the router and applications.

Streaming Library
net.i2p.client.streaming Implements a TCP-like (reliable, authenticated, in order) set of sockets for communicating over the IP-like (unreliable, unauthenticated, unordered) I2P messages.

 

Router
net.i2p.data.i2np The Invisible Internet Network Protocol (I2NP) is only a part of how an application can send messages over the network.
