| 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.epoll | Optimized transport for linux which uses EPOLL Edge-Triggered Mode
 for maximal performance. | 
| io.netty.channel.rxtx | A serial and parallel port communication transport based on RXTX. | 
| io.netty.channel.sctp | Abstract SCTP socket interfaces which extend the core channel API. | 
| io.netty.channel.socket | Abstract TCP and UDP socket interfaces which extend the core channel API. | 
| 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 | UDT Transport. | 
| io.netty.channel.unix | Unix specific transport. |
