A method for repairing multicast/broadcast content via peer to peer communications, which includes receiving at least a part of a file transmitted by a wireless multicast/broadcast service (WMBS) session via an access ndownetwork; exchanging, via a peer to peer network, completion messages between the UE device and peer UE devices upon completion of the WMBS session; identifying an amount of the file received at the UE device, and amounts of the file received at each of peer UE devices based on the exchanged completion messages; sending repair data to repair the file on each peer UE devices in response to identifying that the UE device received the entire file; and sending repair data via the peer to peer network, obtained from the access network, in response to identifying that the UE device received less than the entire file and more of the file than each of the group of peer UE devices.

Aspects of the disclosed subject matter are directed to facilitating peer-to-peer data exchange in a common domain. In accordance with one embodiment, a method is provided for obtaining content from one or more peers that are connected to the domain. The method includes registering a peer with a super-peer when a connection to the domain is established. Then, the connecting peer obtains data that describes various network conditions and identifies chunks of content available from other peers. In downloading content from other peers, heuristics are applied to select between available chunks that are potentially encoded at different bitrates. The heuristics account for the network conditions between peers and balance the potential need to quickly access content with the desire to obtain high quality content.

Systems and methods are provided for sending and receiving remote procedure calls (RPCs). Based on a message in a first RPC, a second set of RPCs are created by one or more computing devices, where each of the second set of RPCs includes a portion of the message in the first RPC. The message in the first RPC is replaced with a reference to each RPC of the second set of RPCs. The one or more computing devices send the first RPC with the references, and also send the second set of RPCs.

Aspects of the present disclosure involve a system and a method for performing operations comprising: storing, on a distributed storage system, a front-end (FE) instance and a plurality of real-time graph (RTG) instances, each of the plurality of RTG instances includes a plurality of device objects, the FE instance being configured to communicate with a client device associated with a first user; establishing a bi-directional streaming remote procedure call (RPC) connection between the FE instance and the plurality of RTG instances; receiving, by the FE instance, a status update from the client device; determining, by the FE instance, that a first device object corresponding to the client device is stored on a first RTG instance of the plurality of RTG instances; and transmitting a first message comprising the status update from the FE instance to the first RTG instance to update the first device object.

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.

An information management method includes: receiving an information import request sent by a first agent node, where the information import request includes a first identifier of a user; obtaining a second identifier of the user based on the information import request, and obtaining to-be-imported personal information corresponding to the second identifier of the user; and sending metadata of the user to a block chain node, to store the metadata of the user into the block chain system. In this way, personal information of the user is registered in the block chain system, so that security of the personal information can be effectively ensured, and the user can perform management of and provide external authorized access to the personal information of the user in a unified manner.

Methods and systems for decentralized storage are provided. To store a file in a decentralized network, a source node in the decentralized network first divides the file into a plurality of file portions. For each given file portion, a corresponding peer storage node is located in the decentralized network, where a distance between the corresponding peer storage node and the given file portion is below a given threshold, where the distance is computed based on an identifier of the corresponding peer storage node, and an identifier of the given file portion, and where the given threshold is associated with a storage capacity of the corresponding peer storage node. The source node then transmits each given file portion to the corresponding peer storage node, and generates a file identifier for the file, based on the identifiers of the plurality of file portions.

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.
