java.lang.Object | +--org.javagroups.stack.Protocol | +--org.javagroups.protocols.WANPIPE
Logical point-to-point link. Uses multiple physical links to provide a reliable transport. For example, if there are 2 physical links over different networks, and one of them fails, the WAN pipe will still be able to send traffic over the other link. Currently traffic is sent over the physical links round-robin, but this will be made configurable in the future. Example: 70% over first link, 30% over second, or packets are split and sent across both links (increasing the available bandwidth).

in class Protocol
public void start() throws java.lang.Exception
Protocol
Channel.connect(String)
. Starts work.
Protocols are connected and queues are ready to receive events.
Will be called from bottom to top. This call will replace
the START and START_OK events.
start
in class Protocol
java.lang.Exception
- Thrown if protocol cannot be started successfully. This will cause the ProtocolStack
to fail, so Channel.connect(String)
will throw an exceptionpublic void stop()
Protocol
Channel.disconnect()
. Stops work (e.g. by closing multicast socket).
Will be called from top to bottom. This means that at the time of the method invocation the
neighbor protocol below is still working. This method will replace the
STOP, STOP_OK, CLEANUP and CLEANUP_OK events. The ProtocolStack guarantees that
when this method is called all messages in the down queue will have been flushed
