Methods and systems for a reciprocal backup of data, including files, directories, and application data are provided. Example embodiments provide a Reciprocal Backup System (“RBS”), which enables users of two or more computer systems connected over a network to engage each other for automated reciprocal backup needs using peer-to-peer computing techniques. The peer computer systems negotiate a reciprocal backup relationship where each provides the other with backup storage in a secure fashion. The intermittent nature of some partners is handled automatically by the RBS, which supports fully automated and scheduled backups as well as immediate backup and restoration of data objects. In one embodiment, the RBS comprises reciprocal backup system partner support and one or more storage repositories. The RBS partner support includes a reciprocal backup manager and scheduler and a reciprocal backup agent. These components cooperate to provide the backup and restoration operations of the RBS.

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..

The invention relates to a method for achieving a real-time video monitoring system based on an internet protocol television top-set box, which is a method for achieving the function of real-time video monitoring on the internet protocol television (IPTV) top-set box. Based on an added-value extended function provided by an IPTV peer-to-peer computing top-set box developed on a dual-core development platform TMS320DM6446 (Vinci digital platform), the invention provides the method for achieving the real-time video monitoring system based on the internet protocol television top-set box for achieving a household real-time video monitoring system on the IPTV top-set box developed on the basis of the DM6446 platform so as to solve the problems of the read-write operations driven by a video capture device, the call of a DSP MPEG-4 coding interface, the transmission and the control of a RTP (Real-time Transport Protocol) data pack, the achievement of MPEG-4 decoding, and the multimedia interface display based on SDL. The proposal has the advantages of novelty, flexibility, easy expansibility, easy operability, low cost and the like.

The invention discloses authentication system and method based on a peer-to-peer computing network. The authentication system comprises a super node, and the super node is used for receiving an authentication request of a user node and authenticating a user which corresponds to the user node according to locally stored authentication information. The invention achieves the effect of enhancing resource utilization rate.
