Is this not because peer discovery needs to take place and if the message expires too quickly this peer discovery may not take place?

Subject: About NonBlockingWireOutputPipe's TTL Setting
Sent: May 11, 2010 07:31
Hello JXTA Dev Team
Hello GF Shoal Dev Team
Sorry for interrupting you.
I come from Fujitsu China and have sth doubt about TTL(time to live) setting
in JXTA's implementation(JXSE).
[Problem]
jxse-src-2.5\impl\src\net\jxta\impl\pipe\NonBlockingWireOutputPipe.java
------------------------------------------------------------
public boolean send(Message message) throws IOException {
... ...
WireHeader header = new WireHeader();
header.setPipeID(getPipeID());
header.setTTL(destPeers.isEmpty() ? 200 : 1); //★My Problem
... ...
}
------------------------------------------------------------
★My Problem:
Is there any special purpose to set TTL to 200 when destPeers is empty?
#why not be set to any other number?
[Background of Problem]
If TTL is set to a big number, I think it may lead bad influence to the overhead
of network. To put down the overhead of network, may I set a number less than 200
for TTL when destPeers is empty?
Could you please give me any comment or suggestion? Any help will be appreciated.
Best Regard
Wu Jie
