[jboss-jira] [JBoss JIRA] (JGRP-726) GossipRouter: support GET and REGISTER via UDP datagram packets

[Bela Ban (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-726?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12643371#comment-12643371 ] 

Bela Ban commented on JGRP-726:
-------------------------------

I think we don't need to wait for the GR overhaul; all that's needed is
- The ability in GossipRouter to listen on a UDP socket (same port as the configured TCP port)
- The ability in RouterStub/RouterStubManager to create UDP sockets and listen for packets
- A flag in GossipRouter to enable TCP and/or UDP
- A flag in RouterStub/RouterStubManger/TCPGOSSIP to use TCP or UDP

> Currently, GossipRouter supports only TCP. If a GossipClient calls register() or getMembers(), then a TCP connection is established and torn down after the request. This is inefficient and leads to many sockets in TIME_WAIT states (which are cleaned up after 2 * MSL seconds).
> If we (in GossipRouter) add an additional listener, which listens on a UDP port, and provide the same for GossipClient, we would not use precious TCP sockets.
> Think about: we should separate the transport in GR from the processing logic, so we could support TCP, UDP, HTTP etc. Should we use JGroups (in unicast mode) for this ?
