Sample UDP transport using Raw Sockets

[satish viswanatham <sa...@gmail.com>]

Hi All,

I came across the following sample implementation. Is there better or
complete version of these sources?

I am only interested in the server (Acceptor) part, not worried about client
(Connector) part yet.

 For example the attached DatagramAcceptor.java  only receives the messages.
What about messages being written out? Starting another "WriterThread" seems
very crude implementation. I checked out the sources and looked at NIO
transport. I guess NIO design is slightly different because of its async
nature.

Even if I were to write another thread to receive "the writes done by the
server" , how does that thread get hold of the write requests.  Should I be
also implementing DatagramService? In that case will I get call back for the
writes?

I am planning to use
Saverese<http://www.savarese.org/software/vserv-tcpip/api/org/savarese/vserv/tcpip/IPPacket.html>
raw sockets. If you have a MINA transport (UDP) using these socket. Please
let me know.

MINA looks nice, wish it had raw transport as well, because with that we
wont be able to use MINA.

thanks
Satish
