Aaron Smuts commented on JCS-46:
--------------------------------
We will have to add this to the UDPDiscoverySender after we create the socket.
This will require changing the constructor to take in another variable.
public UDPDiscoverySender( String host, int port )
throws IOException
{
try
{
m_localSocket = new MulticastSocket();
> Allow TTL to be overridden for UDPDiscoverySender

> Project: JCS
> Issue Type: Improvement
> Components: TCP Lateral Cache
> Reporter: Lux Matic
> Assignee: Aaron Smuts
> Priority: Minor
>
> 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.
