| Package | Description | 
|---|---|
| io.netty.channel | The core channel API which is asynchronous and event-driven abstraction of
 various transports such as a
 NIO Channel. | 
| io.netty.channel.embedded | A virtual  Channelthat helps wrapping a series of handlers to
 unit test the handlers or use them in non-I/O context. | 
| io.netty.channel.epoll | Optimized transport for linux which uses EPOLL Edge-Triggered Mode
 for maximal performance. | 
| io.netty.channel.kqueue | BSD specific transport. | 
| io.netty.channel.local | A virtual transport that enables the communication between the two
 parties in the same virtual machine. | 
| io.netty.channel.nio | NIO-based channel
 API implementation - recommended for a large number of connections (>= 1000). | 
| io.netty.channel.oio | Old blocking I/O based channel API implementation - recommended for
 a small number of connections (< 1000). | 
| io.netty.channel.sctp.nio | NIO-based SCTP Channel
 API implementation - recommended for a large number of connections (>= 1000). | 
| io.netty.channel.sctp.oio | Old blocking I/O based SCTP channel API implementation - recommended for
 a small number of connections (< 1000). | 
| io.netty.channel.socket.nio | NIO-based socket channel
 API implementation - recommended for a large number of connections (>= 1000). | 
| io.netty.channel.socket.oio | Old blocking I/O based socket channel API implementation - recommended for
 a small number of connections (< 1000). | 
| io.netty.channel.udt.nio | UDT Transport for NIO Channels. |
