Abstract
Embodiments of a distributed index mechanism for indexing and searching for presence information in peer-to-peer networks. In one embodiment, a distributed index may be used to store presence information in a decentralized manner on a plurality of peer nodes. In one embodiment, a notification service may be implemented on top of the distributed index to notify peers of other peers joining a peer-to-peer session. Participating peers may query the distributed index to detect the presence of other participating peers registered in the distributed index. One embodiment of a distributed index of presence information may be implemented in peer-to-peer networks implemented according to a peer-to-peer platform including one or more peer-to-peer platform protocols for enabling peer nodes to discover each other, communicate with each other, and cooperate with each other to form peer groups and share network resources.
