Systems and methods are provided that may be implemented to adjust or otherwise vary the number of simultaneous and separate connections that are employed for downloading separate data chunks of a single data file across a network from a single backend data source. A common file hashing algorithm may be extended to provide hashing by parts on multiple sets of data bytes, and may be implemented together with connection logic executing on a frontend client system and the leveraging of backend components.

A set of computers can be grouped into a first group and second group of computers to receive a file object. The first group of computers are commanded to perform a peer-to-peer download of the file object from a source. The second group of computers are commanded to perform a peer-to-peer download of the file object from a computer in the first group of computers.

A unique bag identifier is generated for digital objects to be stored in object storage. A unique download identifier is generated for downloading of these objects and a unique upload identifier is generated for uploading of the objects; all three identifiers are associated in a database. The identifiers are distributed verbally, by electronic mail, by text message, etc. Any holder of these identifiers may access the digital objects without a user account and without installing an application on a computing device other than using a browser. A QR code or alphanumeric code is displayed on a computing device in order to allow another device to access the objects. Objects may be uploaded via electronic mail. Uploading or downloading is protected by an owner-generated password. Digital objects are sealed by calculating their hashes, placing these hashes in a file and calculating a hash for that file. This file hash is submitted to a block chain and a transaction identifier is returned.

Some embodiments of the present application disclose a method, system, device, and server for determining transmission quality of a node, wherein the method comprises: acquiring data transmission information of a preset number of data slices transmitted from a first peer node to a second peer node and before a first slice in the data slices (S11); determining, according to the data transmission information, a data transmission success rate factor corresponding to the first slice (S12); determining, according to the data transmission information, a transmission speed factor corresponding to the first slice (S13); and determining, according to the transmission success rate factor and the transmission speed factor, transmission quality of data transmission from the first peer node to the second peer node (S14). The technical solutions provided by embodiments of the present application can timely judge the transmission quality of the node and improve the transmission efficiency of P2P.

Disclosed herein are a variety of systems, operations, MAC primitives, and procedures for context-aware Peer-to-Peer communications and multi-application Peer-to-Peer communications. An example system for a context-aware Peer-to-Peer communications system may include a physical and Medium Access Control (PHY/MAC) layer and an upper layer above the PHY/MAC layer. The PHY/MAC layer may include at least one of a discovery function, an association function, a data transceiving function, a channel management function, a general scan function, a synchronization function, a power control function, or management and reporting function. The upper layer may be one of a service layer or an application layer.

A system and method for seamless access to remotely manage documents using synchronization of locally stored documents are provided. In some embodiments, a content management server stores documents in a cache on the user's computer. Documents can thus be accessed and edited using the document in the local file system of the user and synchronized with the content management server asynchronously to access the documents on the local files system. Advantageously, the teachings of embodiments as described can be used in conjunction with content management systems for providing faster access to documents in conjunction with editing and for enabling offline work on such documents.

A computer implemented method embodied in a computer program stored in non-transient memory and executed by a computer processor for providing peer to peer content delivery of a live video stream includes delaying delivery of a live stream to a second client to serve that client from a first client that has previously received the live stream. The computer implemented method may further include switching between bad content sources (first clients) to good content sources based on heuristics.

Embodiment includes of a method and a system of network based operation of an unmanned aerial vehicle is disclosed. One system includes a drone user machine, a drone control machine, and a drone control console. The drone control machine is interfaced with the drone user machine through a network. The drone control machine is interfaced with a drone through the drone control console. The drone control machine operates to receive user commands from the drone user machine through the network, and generate drone control commands which are provided to the drone control console for controlling the drone, wherein the drone control commands are generated based on the user commands, and based on virtual flight assistance constraints.

Disclosed are a method and a device for uploading user information, as well as a computer-readable storage medium. The method for uploading user information includes: in response to detection of a user information uploading request, obtaining the user information to be uploaded; storing the user information to be uploaded in an intermediate interface table of an uploading system; selecting the user information to be uploaded from the intermediate interface table at intervals of a predetermined time period, and uploading the user information to be uploaded that is selected to a target user information pool in batches.

A method of facilitating peer-to-peer connection involves transmitting, by a first peer device, an identification of the first peer device and information regarding its capabilities. The information regarding its capabilities including a list of transmission channels that the first peer device is capable of supporting, an indication of which transmission channels the first peer device is capable of supporting as a group owner, and/or an indication of which transmission channels the first peer device is capable of supporting as a client. The first peer device receives from a second peer device, an identification of the second peer device and information regarding its capabilities including a list of transmission channels that the second peer device is capable of supporting. The first peer device and the second peer device then negotiate which of the first and second peer devices should be the group owner and which should be the client.
