Systems and methods of parallel uniform resource identifier resource extraction are provided. A tracking uniform resource identifier (URI) generation component can generate a first uniform resource locator (URL) that, responsive to actuation by a client computing device, causes the client computing device to send a content item identifier of a content item and a device identifier of the client computing device, via a computer network, to a records server at a first network location identified by the first URL. A resource URI generation component can generate a second URL that, responsive to actuation by the client computing device, causes the client computing device to retrieve, via the computer network, a first resource from a second network location identified by the second URL for display by the client computing device. A content item packaging component can generate the content item.

There is provided an information processing system. A terminal device includes a parameter transmission unit that transmits a parameter being used for designating processing which is performed by using a first file; an instruction data transmission unit that transmits instruction data for storing a second file which is a duplicate of the fast file; a control data memory that store control data which includes the parameter and storing location information of the second tile. A control data transmission unit transmits the stored control data, acquires the second file by requiring transmission of the second file based on the storing location information, and transmits the acquired second file to the information processing apparatus which performs processing designated by the parameter included in the control data.

In various implementations, a network device receives a packet from a content producer. The packet includes data and further includes a signature generated by the content producer, based on the data, using a private key of the content producer. The network device modifies the packet without affecting the signature and forwards the modified packet toward a user device. The network device also sends the user device a manifest specifying how the packet was modified. The user device receives the packet and manifest, restores the packet's original data based on the manifest, and verifies the original data using the signature and a public key corresponding to the private key of the content producer. In response to verification of the original data, an application on the user device is allowed to use the data.

A method implemented at a network entity during an instant messaging communication session conducted between a plurality of user terminals over a communications network, the method comprising: receiving a request over the communications network from one of said user terminals, the request comprising a uniform resource indicator that has been exchanged in an instant message during the instant messaging communication session; retrieving media content associated with the uniform resource indicator from a further network entity connected to said network; storing the retrieved media content in a data store connected to said network; and transmitting a response to said user terminal, the response comprising one of (i) at least one identifier of a location in the data store where the retrieved media content was stored; and (ii) the retrieved media content.

A method, an apparatus and a system for migrating application data between terminals are provided. The method includes steps that: the application runs on a first terminal device; a first terminal receives a migration instruction, and acquires resource data of a first state of the application running on the first terminal device, where the first state is a state of the application from starting to receiving the migration instruction; the resource data is stored according to a predetermined storage address; a second terminal device is determined as a migration destination of the resource data, where the second terminal device is provided with the application; and the storage address of the resource data is sent to the second terminal device, so that the second terminal device acquires the resource data by visiting the storage address, and loads the resource data.

The disclosure discloses a method and an apparatus for realizing load balance in a DHT network, wherein the method comprises: determining the quantity Z of first virtual identifiers according to the node planning of the DHT network and a preset threshold of load unbalance degree, wherein Z is a natural number; equally dividing the whole load space of the DHT network into Z portions, and each portion of the load space is respectively identified by a different first virtual identifier; allocating the Z first virtual identifiers to each node according to the ability of each node so that each node is in charge of the load space corresponding to the first virtual identifier allocated to the node. The disclosure can reduce workload for managing and transferring virtual identifiers while realizing data storage load balance in the DHT network.

A server receives a request to upload a file form a user device. The server may generate a unique file ID associated with the file based on the request, and transmit the file ID to the user device. The user device may divide the file to generate multiple slice files and their corresponding slice IDs. From the user device, the server receives the multiple slice files and the slice IDs. Based on the slice IDs, the server may determine storage addresses at which to store the multiple slice files in a distributed storage system using a consistent hash algorithm. The multiple slice files may be stored based on the corresponding storage addresses of the distrusted storage system.

Techniques of network virtualization of containers in cloud-based system are disclosed herein. In one embodiment, a method includes receiving a selection of a host in the computer system to instantiate a container in response to a request from a user. In response to the received selection, the method includes identifying parameters of network operations on the selected host to instantiate the requested container and assigning a network address to the container to be instantiated on the selected host in the computer system, the assigned network address is addressable from outside of the selected host without network name translation. The method can then include transmitting an instruction to the selected host to instantiate the requested container based on the assigned network address.

Systems and methods for performing face recognition and image searching are provided. A system for face recognition and image searching includes an ingestion system, a search system, a user device, and a database of galley files that include feature vectors. The ingestion system crawls the internet starting with a seed URL to scrape image files and generate feature vectors. Feature vectors of images input by a user may be compared by the search system to feature vectors in the gallery files. A method for generating feature vectors includes landmark detection, component aligning, texture mapping, vector computation, comparing cluster centers defined by vectors stored in a database with vectors generated based on an input image, linear discriminant analysis, and principal component analysis.

A replica service of a Content Centric Network can host content published by various publishers, without having to explicitly advertise a name prefix associated with these various publishers. Consumers across CCN can generate an Interest that includes a location-independent name associated with a replica service that hosts content for a given publisher, and includes a hash of the desired Content Object. CCN nodes can forward the Interest to the corresponding replica service based on the Interest's name, and the replica service can return a nameless Content Object whose hash matches the Interest's hash value. It may be possible for nameless Content Objects from various publishers to have matching hash values from time to time. CCN nodes can reduce collisions of nameless Content Objects by using a Publisher ID specified in an Interest to find a matching Content Object that was published by a desired publisher.
