FYI, If you have thoughts on how anycast should work w/ applications, now would be a good time to state them :-)
I think the discussion is probably best done only on the magma list. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks. Security. -- George R.R.

Hello, Has anyone given any thought to whether there should be any (IPv6) anycast addressing API for _applications_? As background, anycast support has usually been implemented either using: 1) an "anycast" flag when configuring an address with system administration -level tools like "ifconfig", or 2) some vendor-specific API which applications can use to signal that they would like to join an anycast "group". As you may note, this is very similar to how multicast works -- which is natural because the model is similar. I know a couple of implementations: most do 1), unofficial anycast support for Linux does 2). I'd be interested if there are other ways to make anycast addressing usable. The advantage of 2) is that it gets closer to applications: when an application using an anycast address (e.g. DNS server software) e.g. crashes, the anycast address automatically gets removed. Of course, there are still failure modes, but I believe this closer to the usage model if we want anycast to be usable for applications, and want to use it robustly. Of course, for some cases, 1) is also useful -- but they are not exclusive, I think. Comments are very much welcome. Should we try to document some simple API for anycast for applications, for example? -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks.
