A system comprises a plurality of nodes coupled via a network. The plurality of nodes are configured to communicate by transmitting and receiving messages between the plurality of nodes. Each message comprises a first version identifier indicative of a first version of an object in a first node of the plurality of nodes, wherein the first node is the transmitter of the message. A second node of the plurality of nodes receives the message, and is configured to upgrade to the first version of the object responsive to the first version identifier indicating that the first version is newer than a second version in the second node (as indicated by a second version identifier in the second node). The second node is configured to include the first version identifier in subsequent messages transmitted by the second node.

Version upgrade via viral infection

Various embodiments of a system and method related to a topology and routing model for a peer-to-peer network are disclosed. A plurality of nodes may be coupled to each other to form a peer-to-peer network. A routing table may be created on each node in the peer-to-peer network. Each node may be operable to route messages to other nodes in the peer-to-peer network using information stored in the routing table. Messages may be propagated among nodes in the peer-to-peer network in a decentralized manner. For example, the peer-to-peer network may not utilize centralized servers of any kind. Each node in the peer-to-peer network may perform substantially the same routing functionality.

Topology and routing model for a computer network

An apparatus comprises a plurality of nodes interconnected as peers in a peer-to-peer network. At least some nodes are configured to update an object, thereby generating a plurality of versions of the object. Any of the plurality of nodes is configured to detect a conflict between a first version and a second version of the plurality of versions, and any of the plurality of nodes is configured to provide an indication of a resolution of the conflict to other ones of the plurality of nodes. Each version may be identified by a version descriptor that includes a version identifier (ID) and a parent version ID. If the version is the result of a conflict resolution, the version descriptor may also include a resolved version ID identifying the losing version. The resolved version ID may be used to prevent the raising of the same conflict after it has been resolved.
