viska VS memberlist

rsip is part of my Rust Voip stack, along with rsip-dns that I have recently been building through viska, a SIP server. SIP protocol is quite tricky to implement, because it's completely P2P so it has some interesting edge cases compared to HTTP which is way more simple. Viska is wip, needed a good SIP library to be productive there, but now that rsip is kinda done, I am gona move back to it :)

I noticed this: https://github.com/vasilakisfil/viska I have not looked at it at all :-) It seems to have been updated fairly recently. Looking at the Readme, there is still a fair way to go, but they've made pretty good progress.

i already found someone with a github repo building a SIP server here: https://github.com/vasilakisfil/viska

That said, there's this, which looks to be on the road already! https://github.com/vasilakisfil/viska

I use lightweight https://github.com/hashicorp/memberlist to build initial cluster skeleton (find out what are nodes constituting it)

Does https://github.com/hashicorp/memberlist count? It’s a gossip-based eventual consistency protocol based on SWIM.

An equivalent of golang's memberlist would be awesome.

I don't know the engineer that did it but I know what happened. There's a library that a bunch of foundational Amazon services use called DFDD. It uses a gossip protocol to handle service discovery and health checking. The open source equivalent is Hashicorp memberlist. To remove a node from the cluster, you have to send a command to an arbitrary node that says a node is dead.

serf uses memberlist which uses the SWIM failure detection protocol (https://www.cs.cornell.edu/projects/Quicksilver/public_pdfs/SWIM.pdf) with the Lifeguard extensions (https://arxiv.org/pdf/1707.00788.pdf).

Fairly idiomatic/clean

This algorithm assumes you're doing that separately using some sort of membership protocol (e.g. SWIM), and you pass in the membership list that you are keeping up to date with that protocol. If you're curious about those, HashiCorp memberlist and HashiCorp Serf are really good to look at. I believe Consul uses those libraries under the hood.
