distributed network / peer discovery #15

Open Raynos opened 11 years ago

Raynos commented 11 years ago

If your creating a peer to peer network. How do you discover the initial topology of the network?

Do you use a fixed list of trackers? Do you have a centralized third party service that maintains meta data about the network topology?

Also how do you solve the chicken and egg problem of you need to connect to a peer to get information about the network shape from him BUT you need to get information about the network shape to know how to connect to the peer.

For joining I guess you always need some point of reference.

You could have as much of those as possible and keep a list of nodes to check when joining.

there can be a set of domains for this! join[0-9a-z].com so you just scan that range.

and always check multiple nodes since they can be corrupt

The question is also what transport medium you use. If it's not tcp/ip, if it's something build for p2p where every node kind of is a router, you wouldn't need to care about that.
