UDP Configuration
- mcast_send_buf_size :
- mcast_recv_buf_size :
- ucast_send_buf_size :
- ucast_recv_buf_size : Network buffer sizes for receiver DatagramSockets and sender MulticastSockets. The bigger the better, because we can avoid packets dropped due to network buffer overflow.
- mcast_port : multicast port number
- mcast_addr : multicast address
- receive_on_all_interfaces : enable receiving multicasts on all interfaces or
- receive_interfaces : list of interfaces for receiving multicasts
- send_on_all_interfaces : enable sending multicasts on all interfaces or
- send_interfaces : list of interfaces for sending multicasts
- bind_addr : the interface to use for unicast or for multicast when [send|receive_interfaces] are not set . If bind_addr is not set, JGroups will pick the first non-loopback NIC
- loopback : Place outgoing packets into the incoming queue (loopback)
- use_incoming_packet_handler : use a separate thread to process incoming messages
- use_outgoing_packet_handler : use a separate thread to process outgoing messages
- ip_ttl : Time-to-live for IP Multicast packets.
- enable_bundling : enable bundling
- max_bundle_size : if 'enable_bundling' is true, specifies the amount of bytes to accumulating
- max_bundle_timeout : if 'enable_bundling' is true, specifies the amount of time to waiting
- diagnostics_addr : multicast addr used for diagnostic messages. By default : 224.0.0.75
- diagnostics_port : multicast port used for diagnostic messages. By default : 7500
- enable_diagnostics : false for disabling the diagnostics

<!--
PING Discovery Protocol
- timeout : The time interval, in milliseconds, to wait for initial membership replies. If the parameter is unspecified, the default value is 3000 milliseconds.
- num_initial_members : Wait for at most 2 initial membership replies, but not longer than "timeout" milliseconds. If the parameter is unspecified, the default value is 2.
-->
<PING timeout="2000"
num_initial_members="3"/>
<!--
MERGE2 Merging Protocol
- max_interval : max nb of seconds to send out a MERGE msg
- min_interval : min nb of seconds to send out a MERGE msg
Interval is a random number between min and max secs.
-->
<MERGE2 max_interval="10000"
min_interval="5000"/>
<!--
FD Failure Detection Protocol
- timeout : nb of msec to wait for the responses to the are-you-alive msg
- max_tries : nb of missed are-you-alive msg from a node before the node is suspected
- shun : true whether a failed node will be shunned
-->
<FD timeout="2000"
max_tries="3"
shun="true"/>
<!--
VERIFY_SUSPECT
Verifies that a suspected member is really dead by pinging that member once again.
- timeout : timout
-->
<VERIFY_SUSPECT timeout="1500"/>
<!--
NAKACK
Lossless and FIFO delivery of multicast messages, using negative acks.
- max_xmit_size : max size of a retransmission
- use_mcast_xmit : specifies whether the sender should send the retransmission to the entire cluster
- gc_lag : nb of msg to keep in the retransmit buffer.
- retransmit_timeout : retransmission time out
-->

<!--
UNICAST Unicast Message
- timeout : retransmission time out
-->
<UNICAST timeout="600,1200,2400,3600"/>
<!--
pbcast.STABLE Distributed garbage collection
- desired_avg_gossip: periodically sends STABLE messages around. 0 disables this
- max_bytes: max number of bytes received from anyone until a STABLE message is sent. Use either this or
desired_avg_gossip, but not both ! 0 disables it.
- stability_delay: range (number of milliseconds) that we wait until sending a STABILITY message.
This prevents STABILITY multicast storms. If max_bytes is used, this should be set to a low value (> 0 though !).
-->
<pbcast.STABLE stability_delay="1000"

<!--
FRAG fragments messages
- frag_size : max frag size in bytes. Messages larger than that are fragmented
- down_thread :
- up_thread :
-->
<FRAG2 frag_size="8192" />
<!--
VIEW_SYNC view reconciliation
- avg_send_interval : period to broadcast the view
- down_thread :
- up_thread :
-->
<VIEW_SYNC avg_send_interval="60000" down_thread="false" up_thread="false" />
<!--
pbcast.GMS Group Member Ship
- print_local_addr : print the node address to the output
- join_timeout : max nb of ms to wait for a new node JOIN request to succeed
- join_retry_timeout : max nb of ms to wait after a failed node joint to re-submit it
- shun : true whether a node should shun itself if it receives a cluster view that it is not a member node
