to be in trouble when your business grows up exponentially and your server
starts to serve tens of thousand clients simultaneously. You could
start with NIO, but it might take much longer time to implement due to
the complexity of the NIO Selector API, hindering your business.

Netty has a central interface called &Channel;. &Channel; abstracts away
all operations required to point-to-point communication. That is, once
you wrote your application on one Netty transport, your application can
run on other Netty transports in most cases. Netty provides the following
transports via this universal I/O API:

provides a number of essential transports via one universal API:

For instance, you could start to write your application with OIO-based
UDP/IP transport first, add TCP/IP support using the OIO-based TCP/IP
transport, and then replace the OIO-based TCP/IP transport with the
NIO-based TCP/IP transport to handle more concurrent connections, all by
replacing just a couple lines of constructor calls in the source code.
Switching from one transport from the other usually takes just a couple
lines of changes such as choosing a different &ChannelFactory;
implementation.

Also, you will even be able to take advantage of a new transport which is
going to be added to Netty, again by replacing just a couple lines of
constructor calls.
not written yet, serial port communication transport for instance, again
by replacing just a couple lines of constructor calls. Moreover, you can
write your own transport by extending the core API because it is highly
extensible.
