[ https://issues.jboss.org/browse/JGRP-1880?page=com.atlassian.jira.plugin.... ] Bela Ban edited comment on JGRP-1880 at 9/23/14 6:38 AM: --------------------------------------------------------- Class {{DatagramChannel}} has the ability to set {{IP_MULTICAST_TTL}} as an option. Investigate whether we can use a {{DatagramChannel}} instead of a {{DatagramSocket}}. Perhaps we can create a {{DatagramChannel}}, but then call {{DatagramChannel.socket()}} to simply use the underlying {{DatagramSocket}} instead. Example: {code} DatagramChannel ch=DatagramChannel.open(); ch.setOption(StandardSocketOptions.IP_MULICAST_TTL, 8); // sets TTL to 8 DatagramSocket sock=ch.socket() // use sock {code} was (Author: belaban): Class {{DatagramChannel}} has the ability to set {{IP_MULICAST_TTL}} as an option.
