  • Publication number: 20170324680
    Abstract: Embodiments of the present invention disclose a data transmission method and apparatus for a terminal. The terminal exchanges data of an application with a server through a first port by using a first access node; when one port in a second port set is in an enabled state, the terminal accesses one access node in a candidate access node set through the enabled port in the second port set, and exchanges, based on the Multipath TCP, the data of the application with the server by using an access node corresponding to the enabled port.

  • Patent number: 9723521
    Abstract: A network handover method, a terminal, a controller, a gateway, and a system. The method includes: when a terminal accesses a first network, converting data including an initial TCP four-tuple into data including a first TCP four-tuple, and sending the data to a gateway; and after handing over from the first network to a second network, converting data including the initial TCP four-tuple into data including a second TCP four-tuple, and sending the data including the second TCP four-tuple to the gateway. This achieves objectives of preventing a connection from being interrupted before and after the network handover, improving use experience, and reducing complexity of a network handover process.

  • Patent number: 9501225
    Abstract: The present disclosure introduces a method and an apparatus of shrinking virtual hard disk image file. The present techniques search a garbage data block in a file and revise a record of the garbage data block in a block allocation table (BAT). The file includes one or more data blocks and a BAT that records information of each data block. The garbage data block is a data block that does not store effective data. The present techniques move an effective data block subsequent to the garbage data block, revise a record of the effective data block in the BAT after the moving, and shrink a size of the file after the movement.

  • Publication number: 20150142760
    Abstract: A method and a device is described for de-duplicating a web page. The method includes: extracting at least one core sentence from a target web page; mapping each core sentence to a unique numeric value to form a first numeric value set; determining an intersection set of the first numeric value set and each second numeric value set, and the number of numeric values included in each intersection set, and determining a maximum number of numeric values included in each intersection set; and when a ratio of the maximum number to a total number of numeric values in the first numeric value set is greater than a set threshold, processing the target web page as a duplicate web page. In embodiments of the present invention, during web page de-duplication processing, accuracy can be improved, an anti-noise capability can be enhanced, and a calculating scale can be reduced.

  • Publication number: 20140108661
    Abstract: The present disclosure discloses a system, a method and an apparatus of data interaction under load balancing to solve the problem of heavy workload of a server load balancer under existing technologies. The system includes a server load balancer, a real server, and a conversion apparatus. A data package, which is sent from a client to a real server, is processed and sent by the server load balancer to the real server. A data package, which is sent from the real server to the client, is processed and sent by the conversion apparatus to the client. Since the traffic flowing from the real server to the client does not pass through the server load balancer but is processed and sent by the conversion apparatus to the client in the above system that is provided by the embodiments of the present disclosure, the workload on the server load balancer is thus effectively reduced.
