RE: [ssm] IGMPv3/SSM API for Java ?

["James Lingard" <James.Lingard@dataconnection.com>]

Toerless,

I'm pretty sure you're right that there's no SSM API, though I can't =
confirm that there's no implicit way of triggering (S,G) membership =
reports.  The following RFE has been raised in Sun's Java bug database =
for this issue (though you may need to register in order to view this =
page):

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=3D4403551

The standard way of encouraging Sun to get bugs fixed is for lots of =
people to vote for them.  See:

http://bugs.sun.com/bugdatabase/top25_bugs.do
http://bugs.sun.com/bugdatabase/top25_rfes.do

I think they do actually pay attention to these.  Currently this RFE has =
only 2 votes (of which one is mine), but if we could encourage lots =
(i.e. >100) of IETF multicast folks to vote for this bug, something =
might happen :)

Other than that, there is something called the Java Community Process =
(see http://jcp.org/en/home/index) by which new APIs and language =
features are often developed, although I'm no expert on how this works.

It also seems that for the next release (J2SE 6.0), Sun are soliciting =
externally contributed code (see =
http://java.sun.com/developer/technicalArticles/J2SE/peabody/).  So if =
there's someone out there with the time to work on this, this route may =
well be the fastest.

Hope that helps,
James.

Looking at

  http://java.sun.com/j2se/1.5.0/docs/api/java/net/MulticastSocket.html

it looks as if Java does NOT have any SSM API, eg: nothing like
JoinSourceGroup(). Can anyone more aware of Java confirm this ? Or
would any Java implementation implicitly trigger at least an IGMPv3
INCLUDE({S},G) membership report whenever a connected datagram socket
was bound to a group (get the source address from connect(), get the
group from JoinGroup() ?) ... I wouldn't think so.. ?

So, assuming the Java world has ignored SSM so far, what can be done
to change this ? I wouldn't even know who defines the API (within ?
outside of Sun ??)

Thanks
