摘要： Various embodiments can utilize a distributed solution for scheduling connections between peers in a file sharing environment. In accordance with at least some embodiments, individual nodes in a peer-to-peer system include scheduling software that enables the nodes to make scheduling decisions with regard to how, when and where connections are made with other peers. Scheduling decisions can be based on a number of different parameters. In at least some embodiments, a synchronization negotiation manager is embodied with logic that drives the negotiation and scheduling process. This logic is represented by an innovative state machine that is designed to implement the negotiation and synchronization process.

摘要： Content synchronization in a file sharing environment is described. A node in a circle share maintains a version vector that represents that node's knowledge of file synchronization events. Version vector data may be transmitted between nodes of the circle share via a presence service in the form of short notification messages. The version vector data is compared to identify one or more nodes to be synchronized. A resource-aware overlay representing the circle share is computed, and is used to initiate communication to determine which of the available nodes with which to synchronize will provide the most synchronization value to other nodes in the circle share.

摘要： Systems and methods for security against corruption for networked storage are described. In one aspect, a destination device receives a linear combination of packets. The linear combination of packets represents digitally signed blocks of content and public information used to digitally sign segmented blocks of content. The destination device recombines the linear combination of packets to compute new valid signatures as linear combinations of received homomorphic digital signatures. The new valid signatures are for verifying by a requesting computing device recovering data associated with at least a subset of the linear combination of packets, integrity of the at least a subset. This provides the requesting node with security against corruption of data in networked storage.

摘要： A content distribution method and system for distributing content over a peer-to-peer network such that the full potential throughput of the network is achieved. The content distribution method divides the content to be distributed into many small blocks. Each of the content blocks then is assigned to a node, which can be a content-requesting node, a non-content-requesting node or a source node. Content is assigned based on a capacity of the node, where nodes having a larger capacity are assigned a greater number of content blocks and nodes having a smaller capacity are assigned a fewer content blocks. The capacity generally is defined as the upload bandwidth of the node. Redistribution queues are employed to control the throughput of the distribution. This bandwidth control strategy ensures that upload bandwidths of the peer and source nodes are fully utilized even with network anomalies such as packet losses and delivery jitters.

摘要： A particular method includes receiving a request from a client at a server and sending a global traffic management identifier in response to the request from the client. The global traffic management identifier is determined based on an attribute of the client. In response to the client requesting access to a service based on a modified hostname of the service, a data center associated with the service is identified based on the modified hostname of the service. The modified hostname identifies the global traffic management identifier, and the identified data center is useable by the client to access the service.

摘要： A plurality of network addresses from a distributed client is obtained, at least a first portion of the obtained network addresses including resolved network address responses to distributed client requests for resolved network addresses corresponding to one or more network location indicators associated with a first web service. Test content is obtained, based on one or more of the network addresses included in the first portion. It is determined whether the obtained test content includes unauthorized content.

摘要： Described is a technology by which a content server downloads an active content measuring tool object to a client request for a page. When loaded, the measuring tool object makes network measurements, including by direct socket access, and return measurement results. As part of its operations, the measuring tool object may request measurement assignments from a central controller, and/or return those results to the central controller. Measurement assignments may be directed towards determining a round trip time/latency, measuring throughput, packet loss rate, detecting in-fight modification of content and/or detecting the presence of a middle box, including the presence of a caching proxy server middle box. The measurement results may be used to evaluate hypothetical deployment of a number of servers and/or geographic locations for those servers.
