/*
The relay package contains the components necessary to implement the "autorelay"
feature.
Warning: the internal interfaces are unstable.
System Components:
- A discovery service to discover public relays.
- An AutoNAT client used to determine if the node is behind a NAT/firewall.
- One or more autonat services, instances of `AutoNATServices`. These are used
by the autonat client.
- One or more relays, instances of `RelayHost`.
- The AutoRelay service. This is the service that actually:
AutoNATService: https://github.com/libp2p/go-libp2p-autonat-svc
AutoNAT: https://github.com/libp2p/go-libp2p-autonat
How it works:
- `AutoNATService` instances are instantiated in the bootstrappers (or other
well known publicly reachable hosts)
- `AutoRelay`s are constructed with `libp2p.New(libp2p.Routing(makeDHT))`
They passively discover autonat service instances and test dialability of
their listen address set through them. When the presence of NAT is detected,
they discover relays through the DHT, connect to some of them and begin
advertising relay addresses. The new set of addresses is propagated to
connected peers through the `identify/push` protocol.
