In some embodiments, a distributed computer network has a server node, a leader node, and a plurality of participant nodes that communicate via a communications network. During a first phase, the leader node generates a leader performance, each participant node receives and renders the leader performance and generates a corresponding participant performance, and the server node receives the leader performance and the participant performances and generates one or more group performances, each including multiple, synchronized performances. During a second phase, the server node transmits the one or more group performances to the participant nodes, and each participant node receives and renders a group performance, thereby allowing a corresponding participant at each participant node to perform along with the rendering of the corresponding group performance. In some implementations, the server node generates different partial group performances, where each participant node receives a partial group performance that excludes the corresponding participant performance.

Disclosed are examples of systems, apparatus, devices, computer program products, and methods implementing aspects of a decentralized content fabric. In some implementations, one or more processors are configured to execute a software stack to define a fabric node of a plurality of fabric nodes of an overlay network situated in an application layer differentiated from an internet protocol layer. The defined fabric node is configured to: obtain a request for digital content from a client device; obtain, from one or more of the plurality of fabric nodes, a plurality of content object parts of a content object representing, in the overlay network, at least a portion of the digital content; generate consumable media using: raw data stored in the content object parts, metadata stored in the content object parts, and build instructions stored in the content object parts; and provide the consumable media to the client device. In some instances, the consumable media is further generated using a digital contract stored in a blockchain.

A method for downloading a data resource includes: at the beginning of downloading a target data resource, determining, by a first device, a plurality of candidate devices storing data slices of the target data resource and slice serial numbers of data slices of the target data resource stored by each of the plurality of candidate devices; acquiring, by the first device, a total number of slices for data slices of a same type of data resources as the target data resource that have been downloaded from each of the plurality of candidate devices; and downloading, by the first device, the data slices of the target data resource according to the slice serial numbers, the total number of slices downloaded from each of the plurality of candidate devices, and a preset time-length for overtime switch.

A system designed for increasing network communication speed for users, while lowering network congestion for content owners and ISPs. The system employs network elements including an acceleration server, clients, agents, and peers, where communication requests generated by applications are intercepted by the client on the same machine. The IP address of the server in the communication request is transmitted to the acceleration server, which provides a list of agents to use for this IP address. The communication request is sent to the agents. One or more of the agents respond with a list of peers that have previously seen some or all of the content which is the response to this request (after checking whether this data is still valid). The client then downloads the data from these peers in parts and in parallel, thereby speeding up the Web transfer, releasing congestion from the Web by fetching the information from multiple sources, and relieving traffic from Web servers by offloading the data transfers from them to nearby peers.

The present disclosure provides a method for requesting resources and a terminal. The terminal sends a first resource acquisition request for a target resource to each of first edge nodes, determines each of second edge nodes based on each first amount of the target resource returned by each of the first edge nodes, and sends a second resource acquisition request for the target resource to each of the second edge nodes.

A computer-implemented method of caching multi-session data communications in a computer network, includes the steps of: (a) receiving, intercepting, or monitoring one or more data sessions between a client executing a multi-session application for retrieving a desired content object and one or more metadata services, said client communicating with the one or more metadata services to discover metadata for the content object; (b) analyzing queries and responses exchanged between the client and the one of more metadata services to discover metadata for the content object; (c) receiving or intercepting subsequent data sessions between the client and content sources; (d) identifying a data protocol used by the client and identifying data queries within the data sessions; (e) identifying the content object or portions thereof requested by the client in the data queries; and (f) determining if the content object or portions thereof are stored in cache and, if so, sending the content object or portions thereof stored in cache to the client, and, if not, sending the data queries to the content sources, storing data responses from the content sources, and sending the data responses to the client.

Disclosed are examples of systems, apparatus, devices, computer program products, and methods implementing aspects of a decentralized content fabric. In some implementations, one or more processors are configured to provide fabric nodes of an overlay network, including one or more fabric nodes that receive a client’s request to access digital content on the overlay network. The request includes an authorization token digitally signed by or on behalf of a user of the client. The fabric node(s) extract a user identifier (ID) from the authorization token, then determine that one or more rules maintained on the overlay network are satisfied. The one or more rules condition access to the digital content upon the extracted user ID matching an ID associated with an owner of a digital instrument. The digital instrument, which can be a non-fungible token, is stored in a blockchain ledger as a unique representation of the digital content.
