Description

MulticastSocket defaults TTL for DatagramPackets to 1. This limits usefulness of the feature. There should be a way to override the TTL through configuration - i.e.: jcs.auxiliary.LTCP.attributes.UdpTTL=4

Assuming m_ttlOverride is available as a member variable - the change boils down to setting the ttl before the packet is sent - something like:

m_localSocket.setTimeToLive(m_ttlOverride);
m_localSocket.send( packet );

See MulticastSocket for more details.
