37 results about "Peer to peer computing" patented technology

Methods, systems, and products are provided for peer-to-peer computer software installation. Embodiments include receiving, by an observing install agent running on an observing host from a test install agent running on a test host, performance information describing the performance of software installed on the test host; determining, by the observing install agent, whether the performance information meets performance criteria for the observing host; and if the performance information meets the performance criteria for the observing host, installing the software on the observing host. In some embodiments, determining, by the observing install agent, whether the performance information meets performance criteria for the observing host is carried out by determining, whether the performance information meets performance criteria for the observing host in dependence upon a rule.

The present invention permits performance adjustment in a virtual universe. In particular, the invention proposes a mixed server-based / peer-to-peer approach, in which transmission responsibilities are shifted towards peer-to-peer computing as the number of avatars within a region increases. The invention may foster fluid business transactions (e.g., sales) during times of high avatar load.

The invention discloses a method for carrying out evaluation and authorization to nodes in a peer-to-peer network by applying a certificate, which provides a safety-oriented authorization scheme in the peer-to-peer network, takes advantage of the features such as the strong dynamism of the peer-to-peer network and the strong independence of the nodes, etc., adopts the authorization scheme that associates evaluation with permission and essentially solves the problem of safe authorization in distributed computation. The method of the invention comprises the steps that: according to the levels of the authority certificate hold by the nodes and the levels of resources that are asked to be accessed by resource requesters, authorized decision-making is carried out by a resource provider; after transaction is finished, the resource providers and the resource requesters directly adopt the certificate to evaluate the performance of the other party; when a node logs in next time, the obtained evaluation certificate and the left authorization certificates are exchanged on a super node firstly so as to obtain the timestamp of a new certificate, continue the afterwards transaction, and improveevaluation rationality and authorization security carried out to node behavior in the peer-to-peer computing field. Compared with other evaluation and authorization schemes, the scheme of the invention is characterized by simplicity and safety, etc..
