Vladimir Blagojevic commented on JGRP-430:
------------------------------------------

Is GR list at RouterStub static or dynamic? Do we update the list with push or pull?

> Multiple GossipRouters can only be used for lookups, not for routing... However, since all traffic to the GR goes out via TUNNEL (as JGroups transport), and TUNNEL uses a RouterStub to send a message to the GR, we could do the following:
>    * the RouterStub is currently configured with the address of *one* GR
>    * a Stub.send() succeeds in connecting to the GR and sending the
>      message, or goes into a state where it tries to reconnect *forever*
>    * I could simply change that to configure the RouterStub with
>      multiple GRs:
>          o for send(), we iterate through the GRs until send() returns
>            true 
> EFFECT: a GossipRouter is not a single point of failure any longer
