Emmanuel Lecharny commented on DIRMINA-539:
-------------------------------------------
What we can do is something like :
boolean isSetTrafficClassAvailable(Socket socket) {
try {
int tc = socket.getTrafficClass();
socket.setTrafficClass((~tc)&0x001E);
boolean supported = (tc != socket.getTrafficClass());
socket.setTrafficClass(tc);
return supported;
} catch (Exception e) {
return false;
}
}
but it seems a bit overkilling...

> Key: DIRMINA-539
> URL: https://issues.apache.org/jira/browse/DIRMINA-539
> Project: MINA
> Issue Type: Bug
> Affects Versions: 2.0.0-M1
> Environment: WinXP, RHEL5 (probably not important)
> Reporter: martin krivosik
> Assignee: Emmanuel Lecharny
> Fix For: 2.0.0-M4
>
> Original Estimate: 0.33h
> Remaining Estimate: 0.33h
>
> client sending datagrams without taking care to the trafficClas set in the
> config, so the ToS byte is not set in the packet sent from client.
> client code:
> NioDatagramAcceptor acceptor = new NioDatagramAcceptor();
> DatagramSessionConfig dcfg =
> ((NioDatagramAcceptor)acceptor).getSessionConfig();
> dcfg.setTrafficClass(tosByte);
> InetSocketAddress bindAddrPort = new InetSocketAddress(originatingIP,
> port);
> acceptor.bind(bindAddrPort);
> -> connecting to another computer with NioDatagramConnector.
> for me it looks like in the newHandle method of NioDatagramConnector is not
> cared about TrafficClass (like it is done in NioDatagramAcceptor.open())
> The server part with the accceptor is OK and the correct ToS byte is set in
> the packet.
> (the same problem may be in the socket, i have to check it)
