Y::Notifier - Specification - The network topology

---

• Y::Notifier consists of a client library and a server application (which is itself a library)
• There are multiple local clients per Notifier server
• There is one Notifier server per host
• Every Notifier server is directly connected to every other Notifier server in a mesh topology
• (earlier implementations had only one server, period)
• Ergo there are n(n - 1)/2 connections between n servers, but each server itself has only n - 1 connections
