Peer Identification

A Tonido peer identification system needs to satisfy several requirements.

Peer ID Requirements

• A physical peer connection needs to be uniquely identified from all other peers so that messages/traffic can be routed correctly
• A PeerID should be independent of the actual network address of the peer (i.e. independent of the IP address of the peer)
• A PeerID should be globally unique
• A PeerID should contain some human usable information
• A PeerID should have enough information for any other Peer to discover it

So a PeerID in Tonido is composed of the following:

nickname@Domain

Domain is the Tonido Domain Server to which the Peer is attached. The Domain part is generally a string which is of the form of Host:Port. Note that the Host can be a IPv4 address, (future IPv6 address) or a resolvable host name (like www.yahoo.com).

Nickname is an optional user chosen handle. This is also a variable length string.
