byte communication using tcp client

[이희승 (Trustin Lee)]

The protocol looks like an ASCII text line protocol. I'd suggest you to refer to the telnet example as a starting point.

Hi Christian,
The transmission of data between DAC and client application is using tcp. So thought of using netty for that.

Thanks,
Rajiv.

Hi Rajiv,

if these DAC are not accessible via a network interface and the wire
protocol you're describing isn't acting on top of TCP or UDP, there is
no support for that in "out-of-the-box" Netty. You can, of course,
implement access to that controllers as a "transport" in Netty and
after that utilize Nettys good API and (possibly) benefit from
exchangeable transports of your protocol.


hth,

christian!
