Neil needed something different, with SSL tunnels and different views of the controller's addresses, and that why we improved Appia a little bit to allow more configurations.
Hi Nuno, Please see the comments below: I don't want to use multicast. Controllers can be on a WAN. So I'd rather use some form of unicast with gossip/epidemic protocols, while SSH tunnels and so on aren't all that important to me. > > Appia uses a gossip SERVICE to discover new members and merge concurrent membership views. This service runs in one of the protocols of all members and they only need some type of communication for the initial discovery messages. This can use a multicast address OR a simple server that only forwards discovery messages to other members that it knows. This server acts just like a proxy and can be replicated by running several instances in different machines. > Wonderful! That's what I need - an ability to run more that 1 gossip server with authomatic switch of clients if one of them is down and no multicast.
