G2 Network Size
|Leaves per Hub
|Hubs per Leaf
- Hub nodes form the core of the G2 network.
They accept connections from hundreds of
leaves and a handful of hubs. They receive searches from neighbors and forward
them to other neighbors. Hubs are the only node type that the crawler indexes.
Hubs provide information about their connected leaves to the crawler. From this
information the crawler learns about the approximate size of the network and
other interesting statistics.
- Leaf nodes are the most common node type
on the network. They have no special responsibilities and do not form a
working part of the network infrastructure. They connect to hubs and send
searches to hubs which will forward their searches to more hubs and leaves.
- Unique nodes is the number of actual users
that are on the network. The number of leaves is an overcount because leaves
connect to more than one hub (usually two) and so each hub counts them as their
own. But the Unique nodes count removes all the duplicates and
returns the real size of the network.
- Leaves per hub is a simple ratio of the
number of leaves divided by the number of hubs.
- Hubs per leaf is the average number of
hubs that each leaf is connected to. Shareaza defaults to connecting to two
hubs in leaf mode so this average should stay around two.
